About SecureStack C2 Switch Operation in a Stack The SecureStack C2 products are stackable switches that can be adapted and scaled to help meet your network needs. These switches provide a management platform and uplink to a network backbone for a stacked group of up to eight SecureStack C2 switches. Note: You can mix SecureStack C2 and C3 switches in a single stack, although only the lowest common denominator of functionality will be supported in a mixed stack. Refer to “Issues Related to Mixed Type Stacks”...
Installing a New Stackable System of Up to Eight Units • The console port on the manager switch remains active for out‐of‐band (local) switch management, but the console port on each member switch is deactivated. This enables you to set the IP address and system password using a single console port. Now each switch can be configured locally using only the manager’s console port, or inband using a remote device and the CLI set of commands described in this section. Once a stack is created (more than one switch is interconnected), the following procedure occurs: By default, unit IDs are arbitrarily assigned on a first‐come, first‐served basis. Unit IDs are saved against each module. Then, every time a board is power‐cycled, it will initialize with the same unit ID. This is important for port‐specific information (for example: ge.4.12 is the 12th Gigabit Ethernet port on Unit # 4). The management election process uses the following precedence to assign a management switch: Previously assigned / elected management unit b. Management assigned priority (values 1‐15) Hardware preference level d. Highest MAC Address Use the following recommended procedures when installing a new stackable system or adding a new unit to an existing stack. Important The following procedures assume that all units have a clean configuration from manufacturing. When adding a new unit to an already running stack, it is also assumed that the new unit is using the same firmware image version as other units in the stack.
Use the show switch command to redisplay stacking information. If the new member displays as unit 2, you can proceed to repeat this step with the next unit. b. If the new member displays a different unit number, you must: Renumber the stack using the set switch renumber command as described in “set switch” on page 2‐9, then (2) Clear the original unit number using the clear switch member command. Repeat Step 6 until all members have been renumbered in the order you desire. After the stack has been reconfigured, you can use the show switch unit command (“show switch” on page 2‐6) to physically confirm the identity of each unit. When you enter the command with a unit number, the MGR LED of the specified switch will blink for 10 seconds. The normal state of this LED is off for member units and steady green for the manager unit. Adding a New Unit to an Existing Stack Use the following procedure for installing a new unit to an existing stack configuration. This procedure assumes that the new unit being added has a clean configuration from manufacturing and is running the same firmware image version as other units in the stack. Ensure that power is off on the new unit being installed. Use one of the following methods to complete stack cable connections: – If the running stack uses a daisy chain topology, make the stack cable connections from the bottom of the stack to the new unit (that is, STACK DOWN port from the bottom unit of the running stack to the STACK UP port on the new unit). – If the running stack uses a ring stack topology, break the ring and make the stack cable connections to the new unit to close the ring. Apply power to the new unit. SecureStack C2 Configuration Guide 2-3...
Creating a Virtual Switch Configuration Creating a Virtual Switch Configuration You can create a configuration for a SecureStack C2 switch before adding the actual physical device to a stack. This preconfiguration feature includes configuring protocols on the ports of the “virtual switch.” To create a virtual switch configuration in a stack environment: Display the types of switches supported in the stack, using the show switch switchtype command (page 2‐7). Using the output of the show switch switchtype command, determine the switch index (SID) of the model of switch being configured. Add the virtual switch to the stack using the set switch member command (page 2‐11). Use the SID of the switch model, determined in the previous step, and the unit ID that you want to assign to this switch member. Proceed to configure the ports of the virtual switch as you would do for physically present devices. The following example adds a C2G124‐24 mode to a stack as unit 2 of the stack. The first port on that virtual switch is then associated with VLAN 555.

• Use clear ip address to remove the IP address of the stack. • Use clear license to remove an applied license from a switch. Configuration parameters and stacking information can also be cleared on the master unit only by selecting the “restore configuration to factory defaults” option from the boot menu on switch startup. This selection will leave stacking priorities on all other units. Issues Related to Mixed Type Stacks Feature Support Because the SecureStack C2 and C3 switches have different hardware architectures, the functionality supported by the two switch types is different. When the two types of switches are mixed in a stack, the functionality supported will be the lowest common denominator of features supported on all platforms. Refer to the firmware Release Notes for information about supported features. Configuration Common Firmware Version Mixed stacking is only supported by SecureStack C2 firmware version 5.00.xx and higher. In order to mix SecureStack C3 switches with C2 switches, you must install the C2 firmware (version 5.00.xx or higher) on the C3 switch. You can install the C2 firmware first, with the C3 switch in stand‐alone mode, or you can add the C3 switch to the stack and then copy the C2 firmware to the C3 switch using the set switch copy‐fw command (page 2‐10). After copying the C2 firmware to the C3 switch, you must reset the stack. Switch Manager It is recommended that a SecureStack C3 switch be made the manager of a mixed stack. Use the set switch movemanagement command (page 2‐11) to change the manager unit. SecureStack C2 Configuration Guide 2-5...

Managing Switch Configuration and Files Managing Switch Configuration and Files Configuration Persistence Mode The default state of configuration persistence mode is “auto,” which means that when CLI configuration commands are entered, or when a configuration file stored on the switch is executed, the configuration is saved to NVRAM automatically at the following intervals: • On a stand‐alone unit, the configuration is checked every two minutes and saved if there has been a change. • On a stack, the configuration is saved across the stack every 30 minutes if there has been a change. If you want to save a running configuration to NVRAM more often than the automatic intervals, execute the save config command and wait for the system prompt to return. After the prompt returns, the configuration will be persistent. You can change the persistence mode from “auto” to “manual” with the set snmp persistmode command. If the persistence mode is set to “manual,” configuration commands will not be automatically written to NVRAM. Although the configuration commands will actively modify the running configuration, they will not persist across a reset unless the save config command has been executed. Purpose To set and view the persistence mode for CLI configuration commands, manually save the running configuration, view, manage, and execute configuration files and image files, and set and view TFTP parameters. Commands For information about... Refer to page... show snmp persistmode 3-37 set snmp persistmode...

Defaults If all is not specified, stacking configuration parameters will not be cleared. Mode Switch command, read‐write. Usage Executing this command will clear the configuration in both NVRAM and on the memory card, if one is installed on the switch. This command will not clear the IP address of the switch. Use the clear ip address command to clear the IP address. When using the clear config command to clear configuration parameters in a stack, it is important to remember the following: • Use clear config to clear configuration parameters without clearing stack unit IDs. This command WILL NOT clear stack parameters and avoids the process of re‐numbering the stack. • Use clear config all when it is necessary to clear all configuration parameters, including stack unit IDs (if applicable) and switch priority values. • Use the clear ip address command to clear the IP address. Configuration parameters and stacking information can also be cleared on the master unit only by selecting option 10 (restore configuration to factory defaults) from the boot menu on switch startup. This selection will leave stacking priorities on all other units, if applicable. Example This example shows how to clear configuration parameters (including stacking parameters, if applicable): C2(su)->clear config all Using and Configuring WebView Purpose By default, WebView (The Enterasys Networks embedded web server for switch configuration and management tasks) is enabled on TCP port number 80 on the SecureStack C2 switch.

Instructs attached phone to allow the device connected to it to transmit traffic containing any CoS or Layer 2 802.1p marking. This is the default value. Instructs attached phone to overwrite the 802.1p tag of traffic transmitted by the device connected to it to 0, by default, or to the value configured with the cos parameter. cos value Instructs attached phone to overwrite the 802.1p tag of traffic transmitted by the device connected to it with the specified value, when the trust mode of the port is set to untrusted. Value can range from 0 to 7, with 0 indicating the lowest priority. port‐string Specifies the port(s) on which status will be set. Defaults Status: enabled Voice VLAN: none Trust mode: trusted CoS value: 0 Mode Switch mode, read‐write. Usage The following points describe how the Cisco DP extended trust settings work on the switch. • A Cisco DP port trust status of trusted or untrusted is only meaningful when a Cisco IP phone is connected to a switch port and a PC or other device is connected to the back of the Cisco IP phone. • A Cisco DP port state of trusted or untrusted only affects tagged traffic transmitted by the device connected to the Cisco IP phone. Untagged traffic transmitted by the device connected to the Cisco IP phone is unaffected by this setting. • If the switch port is configured to a Cisco DP trust state of trusted (with the trusted yes parameter of this command), this setting is communicated to the Cisco IP phone instructing it to allow the device connected to it to transmit traffic containing any CoS or Layer 2 802.1p marking. SecureStack C2 Configuration Guide 4-11...
clear ciscodp • If the switch port is configured to a Cisco DP trust state of untrusted (trusted no), this setting is communicated to the Cisco IP phone instructing it to overwrite the 802.1p tag of traffic transmitted by the device connected to it to 0, by default, or to the value specified by the cos parameter of this command. • There is a one‐to‐one correlation between the value set with the cos parameter and the 802.1p value assigned to ingressed traffic by the Cisco IP phone. A value of 0 equates to an 802.1p priority of 0. Therefore, a value of 7 is given the highest priority. Note: The Cisco Discovery Protocol must be globally enabled using the set ciscodp status command before operational status can be set on individual ports. Examples This example shows how to set the Cisco DP port voice VLAN ID to 3 on port .1.6 and enable the port operational state. C2(rw)->set ciscodp port status enable vvid 3 ge.1.6 This example shows how to set the Cisco DP extended trust mode to untrusted on port ...
Configuring Link Layer Discovery Protocol and LLDP-MED Overview The Link Layer Discovery Protocol (LLPD) is similar to the Enterasys Discovery Protocol and the Cisco Discovery Protocol in that it provides an industry standard, vendor‐neutral way to allow network devices to advertise their identities and capabilities on a local area network, and to discover that information about their neighbors. LLDP‐MED is an enhancement to LLDP that provides the following benefits: • Extended and automated power management of Power over Ethernet endpoints • Inventory management, allowing network administrators to track their network devices and to determine their characteristics, such as manufacturer, software and hardware versions, and serial or asset numbers The information sent by an LLDP‐enabled device is extracted and tabulated by its peers. The communication can be done when information changes or on a periodic basis. The information tabulated is aged to ensure that it is kept up to date. Ports can be configured to send this information, receive this information, or both send and receive. Either LLDP or LLDP‐MED, but not both, can be used on an interface between two devices. A switch port uses LLDP‐MED when it detects that an LLDP‐MED‐capable device is connected to it. LLDP information is contained within a Link Layer Discovery Protocol Data Unit (LLDPDU) sent in a single 802.3 Ethernet frame. The information fields in LLDPDU are a sequence of short, variable‐length, information elements known as TLVs — type, length, and value fields where: • Type identifies what kind of information is being sent • Length indicates the length of the information string in octets • Value is the actual information that needs to be sent The LLDP standard specifies that certain TLVs are mandatory in transmitted LLDPDUs, while others are optional. You can configure on a port‐specific basis which optional LLDP and LLDP‐ MED TLVs should be sent in LLDPDUs. Purpose To review and configure LLPD and LLPD‐MED.

What It Displays... System Priority System priority value which determines aggregation precedence. Only one LACP system priority can be set on a SecureStack C2 device, using either the set lacp asyspri command (page 5-37), or the set port lacp command...
set lacp aadminkey Parameters asyspri Sets the system priority to be used in creating a LAG (Link Aggregation Group) ID. Valid values are 0 to 65535. value Specifies a system priority value. Valid values are 0 to 65535, with precedence given to lower values. Defaults None. Mode Switch command, read‐write. Usage LACP uses this value to determine aggregation precedence. If there are two partner devices competing for the same aggregator, LACP compares the LAG IDs for each grouping of ports. The LAG with the lower LAG ID is given precedence and will be allowed to use the aggregator. Example This example shows how to set the LACP system priority to 1000: C2(su)->set lacp asyspri 1000 set lacp aadminkey Use this command to set the administratively assigned key for one or more aggregator ports.

6-28 Creating a Basic SNMP Trap Configuration 6-36 SNMP Configuration Summary SNMP is an application‐layer protocol that facilitates the exchange of management information between network devices. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. SecureStack C2 devices support three versions of SNMP: • Version 1 (SNMPv1) — This is the initial implementation of SNMP. Refer to RFC 1157 for a full description of functionality. • Version 2 (SNMPv2c) — The second release of SNMP, described in RFC 1907, has additions and enhancements to data types, counter size, and protocol operations. • Version 3 (SNMPv3) — This is the most recent version of SNMP, and includes significant enhancements to administration and security. SNMPv3 is fully described in RFC 2571, RFC 2572, RFC 2573, RFC 2574, and RFC 2575. SNMPv1 and SNMPv2c The components of SNMPv1 and SNMPv2c network management fall into three categories: • Managed devices (such as a switch). • SNMP agents and MIBs, including SNMP traps, community strings, and Remote Monitoring (RMON) MIBs, which run on managed devices. SecureStack C2 Configuration Guide 6-1...
SNMP Configuration Summary • SNMP network management applications, such as the Enterasys NetSight application, which communicate with agents to get statistics and alerts from the managed devices. SNMPv3 SNMPv3 is an interoperable standards‐based protocol that provides secure access to devices by authenticating and encrypting frames over the network. The advanced security features provided in SNMPv3 are as follows: – Message integrity — Collects data securely without being tampered with or corrupted. – Authentication — Determines the message is from a valid source. – Encryption — Scrambles the contents of a frame to prevent it from being seen by an unauthorized source. Unlike SNMPv1 and SNMPv2c, in SNMPv3, the concept of SNMP agents and SNMP managers no longer apply. These concepts have been combined into an SNMP entity. An SNMP entity consists of an SNMP engine and SNMP applications. An SNMP engine consists of the following four components: • Dispatcher — This component sends and receives messages. • Message processing subsystem — This component accepts outgoing PDUs from the dispatcher and prepares them for transmission by wrapping them in a message header and returning them to the dispatcher. The message processing subsystem also accepts incoming messages from the dispatcher, processes each message header, and returns the enclosed PDU to the dispatcher. • Security subsystem — This component authenticates and encrypts messages. • Access control subsystem — This component determines which users and which operations are allowed access to managed objects. About SNMP Security Models and Levels An SNMP security model is an authentication strategy that is set up for a user and the group in ...
Using SNMP Contexts to Access Specific MIBs By default, when operating from the switch CLI, SecureStack C2 devices allow access to all SNMP MIBs or contexts. A context is a collection of MIB objects, often associated with a particular physical or logical device. If no optional context parameters are configured for v1 and v2 “community” names and v3 “user” groups, these groups are able to access all SNMP MIB objects when in switch mode. Specifying a context parameter when setting up SNMP user group would permit or restrict the group’s switch management access to the MIB(s) specified by the context (MIB object ID) value. All SNMP contexts known to the device can be displayed using the show snmp context command as described in “show snmp context” on page 6‐20. Example This example permits the “powergroup” to manage all MIBs via SNMPv3: C2(su)->set snmp access powergroup security-model usm Configuration Considerations Commands for configuring SNMP on the SecureStack C2 device are independent during the SNMP setup process. For instance, target parameters can be specified when setting up optional notification filters — even though these parameters have not yet been created with the set snmp targetparams command.

Configuring SNMP Notification Parameters Configuring SNMP Notification Parameters About SNMP Notify Filters Profiles indicating which targets should not receive SNMP notification messages are kept in the NotifyFilter table. If this table is empty, meaning that no filtering is associated with any SNMP target, then no filtering will take place. “Traps” or “informs” notifications will be sent to all destinations in the SNMP targetAddrTable that have tags matching those found in the NotifyTable. When the NotifyFilter table contains profile entries, the SNMP agent will find any filter profile name that corresponds to the target parameter name contained in an outgoing notification message. It will then apply the appropriate subtree‐specific filter when generating notification messages. Purpose To configure SNMP notification parameters and optional filters. Notifications are entities which handle the generation of SNMP v1 and v2 “traps” or SNMP v3 “informs” messages to select management targets. Optional notification filters identify which targets should not receive notifications.

The following configuration example shows how to use CLI commands to associate SNMP notification parameters with security and authorization criteria (target parameters), and map the parameters to a management target address. Note: This example illustrates how to configure an SNMPv2 trap notification. Creating an SNMPv1 or v3 Trap, or an SNMPv3 Inform notification would require using the same commands with different parameters, where appropriate.
C2(su)->set snmp notify entry1 tag TrapSink C2(su)->set snmp targetaddr tr 192.168.190.80 param v2cExampleParams taglist TrapSink How SNMP Will Use This Configuration In order to send a trap/notification requested by a MIB code, the SNMP agent requires the equivalent of a trap “door”, a “key” to unlock the door, and a “procedure” for crossing the doorstep. To determine if all these elements are in place, the SNMP agent proceeds as follows: Determines if the “keys” for trap “doors” do exist. In the example configuration above, the key that SNMP is looking for is the notification entry created with the set snmp notify command which, in this case, is a key labeled entry1. Searches for the doors matching such a key. For example, the parameters set for the entry1 key shows that it opens only the door TrapSink. Verifies that the specified door TrapSink is, in fact, available. In this case it was built using the set snmp targetaddr command. This command also specifies that this door leads to the management station 192.168.190.80, and the “procedure” (targetparams) to cross the doorstep is called v2ExampleParams. Verifies that the v2ExampleParams description of how to step through the door is, in fact, there. The agent checks targetparams entries and determines this description was made with the set snmp targetparams command, which tells exactly which SNMP protocol to use and what community name to provide. In this case, the community name is mgmt. Verifies that the mgmt community name is available. In this case, it has been configured using the set snmp community command. Sends the trap notification message. SecureStack C2 Configuration Guide 6-37...
Otherwise, the proper operation of the network could be at risk. Spanning Tree Configuration Summary Overview: Single, Rapid, and Multiple Spanning Tree Protocols The IEEE 802.1D Spanning Tree Protocol (STP) resolves the problems of physical loops in a network by establishing one primary path between any two devices in a network. Any duplicate paths are barred from use and become standby or blocked paths until the original path fails, at which point they can be brought into service. RSTP The IEEE 802.1w Rapid Spanning Protocol (RSTP), an evolution of 802.1D, can achieve much faster convergence than legacy STP in a properly configured network. RSTP significantly reduces the time to reconfigure the network’s active topology when physical topology or configuration parameter changes occur. It selects one switch as the root of a Spanning Tree‐connected active topology and assigns port roles to individual ports on the switch, depending on whether that port is part of the active topology. RSTP provides rapid connectivity following the failure of a switch, switch port, or a LAN. A new root port and the designated port on the other side of the bridge transition to forwarding through an explicit handshake between them. By default, user ports are configured to rapidly transition to forwarding in RSTP. MSTP The IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) builds upon 802.1D and RSTP by optimizing utilization of redundant links between switches in a network. When redundant links exist between a pair of switches running single STP, one link is forwarding while the others are SecureStack C2 Configuration Guide 7-1...
Spanning Tree Configuration Summary blocking for all traffic flowing between the two switches. The blocking links are effectively used only if the forwarding link goes down. MSTP assigns each VLAN present on the network to a particular Spanning Tree instance, allowing each switch port to be in a distinct state for each such instance: blocking for one Spanning Tree while forwarding for another. Thus, traffic associated with one set of VLANs can traverse a particular inter‐switch link, while traffic associated with another set of VLANs can be blocked on that link. If VLANs are assigned to Spanning Trees wisely, no inter‐switch link will be completely idle, maximizing network utilization. For details on creating Spanning Tree instances, refer to “set spantree msti” on page 7‐12. For details on mapping Spanning Tree instances to VLANs, refer to “set spantree mstmap” on page 7‐14. Note: MSTP and RSTP are fully compatible and interoperable with each other and with legacy STP 802.1D. Spanning Tree Features The SecureStack C2 device meets the requirements of the Spanning Tree Protocols by performing the following functions: • Creating a single Spanning Tree from any arrangement of switching or bridging elements. •...
• Communicating port non‐forwarding status through traps and syslog messages • Disabling a port based on frequency of failure events Port forwarding state in the designated port is gated by a timer that is set upon BPDU reception. It is analogous to the rcvdInfoWhile timer the port uses when receiving root information in the root/ alternate/backup role. There are two operational modes for Loop Protect on a port. If the port is connected to a device known to implement Loop Protect, it uses full functional mode. Otherwise the port operates in limited functional mode. Connection to a Loop Protect switch guarantees that the alternate agreement mechanism is implemented. This means the designated port can rely on receiving a response to its proposal regardless of the role of the connected port, which has two important implications. First, the designated port connected to a non‐root port may transition to forwarding. Second, there is no ambiguity when a timeout happens; a Loop Protect event has occurred. In full functional mode, when a type 2 BPDU is received and the port is designated and point‐to‐ point, the timer is set to 3 times helloTime. In limited functional mode there is the additional requirement that the flags field indicate a root role. If the port is a boundary port the MSTIs for that port follow the CIST, that is, the MSTI port timers are set according to the CIST port timer. If the port is internal to the region then the MSTI port timers are set independently using the particular MSTI message. Message age expiration and the expiration of the Loop Protect timer are both Loop Protect events. A notice level syslog message is produced for each such event. Traps may be configured to report these events as well. A syslog message and trap may be configured for disputed BPDUs. It is also configurable to force the locking of a SID/port for the occurrence of one or more events. When the configured number of events happen within a given window of time, the port is forced into blocking and held there until it is manually unlocked via management. Configuring Spanning Tree Bridge Parameters Purpose To display and set Spanning Tree bridge parameters, including device priorities, hello time, maximum wait time, forward delay, path cost, and topology change trap suppression.

Syntax set spantree mstcfgid {cfgname name | rev level} Parameters cfgname name Specifies an MST configuration name. rev level Specifies an MST revision level. Valid values are 0 ‐ 65535. Defaults None.
Defaults If sid is not specified, priority will be set on Spanning Tree 0. Mode Switch command, read‐write. Usage The device with the highest priority (lowest numerical value) becomes the Spanning Tree root device. If all devices have the same priority, the device with the lowest MAC address will then become the root device. Depending on the bridge priority mode (set with the set spantree bridgeprioritymode command described in “set spantree bridgeprioritymode” on page 7‐10, some priority values may be rounded up or down. Example This example shows how to set the bridge priority to 4096 on SID 1: C2(su)->set spantree priority 4096 1 clear spantree priority Use this command to reset the Spanning Tree priority to the default value of 32768. Syntax clear spantree priority [sid] Parameters (Optional) Resets the priority on a specific Spanning Tree. Valid values are 0 ‐ 4094. If not specified, SID 0 is assumed. Defaults If sid is not specified, priority will be reset on Spanning Tree 0. Mode Switch command, read‐write. SecureStack C2 Configuration Guide 7-17...
set spantree hello Example This example shows how to reset the bridge priority on SID 1: C2(su)->clear spantree priority 1 set spantree hello Use this command to set the device’s Spanning Tree hello time, This is the time interval (in seconds) the device will transmit BPDUs indicating it is active. Syntax set spantree hello interval Parameters interval Specifies the number of seconds the system waits before broadcasting a bridge hello message (a multicast message indicating that the system is active). Valid values are 1 ‐ 10. Defaults None. Mode Switch command, read‐write. Example This example shows how to globally set the Spanning Tree hello time to 10 seconds: C2(su)->set spantree hello 10 clear spantree hello Use this command to reset the Spanning Tree hello time to the default value of 2 seconds. Syntax clear spantree hello Parameters None.
Specifies the maximum number of seconds that the system retains the information received from other bridges through STP. Valid values are 6 ‐ Defaults None. Mode Switch command, read‐write. Usage The bridge maximum aging time is the maximum time (in seconds) a device can wait without receiving a configuration message (bridge “hello”) before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STP information provided in the last configuration message becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network. Example This example shows how to set the maximum aging time to 25 seconds: C2(su)->set spantree maxage 25 clear spantree maxage Use this command to reset the maximum aging time for a Spanning Tree to the default value of 20 seconds. Syntax clear spantree maxage Parameters None. Defaults None. Mode Switch command, read‐write. SecureStack C2 Configuration Guide 7-19...
set spantree fwddelay Example This example shows how to globally reset the maximum aging time: C2(su)->clear spantree maxage set spantree fwddelay Use this command to set the Spanning Tree forward delay. Syntax set spantree fwddelay delay Parameters delay Specifies the number of seconds for the bridge forward delay. Valid values are 4 ‐ 30. Defaults None. Mode Switch command, read‐write. Usage The forward delay is the maximum time (in seconds) the root device will wait before changing states (i.e., listening to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result. Example This example shows how to globally set the bridge forward delay to 16 seconds: C2(su)->set spantree fwddelay 16 clear spantree fwddelay Use this command to reset the Spanning Tree forward delay to the default setting of 15 seconds. ...
Example This example shows how to display the status of the backup root function on SID 0: C2(rw)->show spantree backuproot Backup root is set to disable on sid 0 set spantree backuproot Use this command to enable or disable the Spanning Tree backup root function on the switch. Syntax set spantree backuproot sid {disable | enable} Parameters Specifies the Spanning Tree instance on which to enable or disable the backup root function.Valid values are 0 ‐ 4094. disable | enable Enables or disables the backup root function. Defaults None. Mode Switch command, read‐write. SecureStack C2 Configuration Guide 7-21...
clear spantree backuproot Usage The Spanning Tree backup root function is disabled by default on the SecureStack C2. When this feature is enabled and the switch is directly connected to the root bridge, stale Spanning Tree information is prevented from circulating if the root bridge is lost. If the root bridge is lost, the backup root will dynamically lower its bridge priority so that it will be selected as the new root over the lost root bridge. Example This example shows how to enable the backup root function on SID 2: C2(rw)->set spantree backuproot 2 enable clear spantree backuproot Use this command to reset the Spanning Tree backup root function to the default state of disabled. Syntax clear spantree backuproot sid Parameters Specifies the Spanning Tree on which to clear the backup root function.Valid values are 0 ‐ 4094. Defaults None. Mode Switch command, read‐write. Example This example shows how to reset the backup root function to disabled on SID 2: C2(rw)->clear spantree backuproot 2 show spantree tctrapsuppress Use this command to display the status of topology change trap suppression on Rapid Spanning ...
{disable | enable} Parameters disable | enable Disables or enables topology change trap suppression. Defaults None. Mode Switch command, read‐write. Usage By default, RSTP non‐edge (bridge) ports that transition to forwarding or blocking cause the switch to issue a topology change trap. When topology change trap suppression is enabled, which is the device default, edge ports (such as end station PCs) are prevented from sending topology change traps. This is because there is usually no need for network management to monitor edge port STP transition states, such as when PCs are powered on. When topology change trap suppression is disabled, all ports, including edge and bridge ports, will transmit topology change traps. Example This example shows how to allow Rapid Spanning Tree edge ports to transmit topology change traps: C2(rw)->set spantree tctrapsuppress disable clear spantree tctrapsuppress Use this command to clear the status of topology change trap suppression on Rapid Spanning Tree edge ports to the default state of enabled (edge port topology changes do not generate traps). Syntax clear spantree tctrapsuppress SecureStack C2 Configuration Guide 7-23...
set spantree protomigration Parameters None. Defaults None. Mode Switch command, read‐write. Example This example shows how to clear topology change trap suppression setting: C2(rw)->clear spantree tctrapsuppress set spantree protomigration Use this command to reset the protocol state migration machine for one or more Spanning Tree ports. When operating in RSTP mode, this forces a port to transmit MSTP BPDUs. Syntax set spantree protomigration <port-string> Parameters port‐string Reset the protocol state migration machine for specific port(s). For a detailed description of possible port‐string values, refer to “Port String Syntax Used in the CLI” on page 5‐2. Defaults None. Mode Switch command, read‐write. Example This example shows how to reset the protocol state migration machine on port 20: C2(su)->set spantree protomigration ge.1.20 show spantree spanguard Use this command to display the status of the Spanning Tree SpanGuard function.
{enable | disable} Parameters enable | disable Enables or disables the SpanGuard function. Defaults None. Mode Switch command, read‐write. Usage SpanGuard is designed to disable, or lock out an “edge” port when an unexpected BPDU is received. The port can be configured to be re‐enabled after a set time period, or only after manual intervention. A port can be defined as an edge (user) port using the set spantree adminedge command, described in “set spantree adminedge” on page 7‐37. A port designated as an edge port is expected to be connected to a workstation or other end‐user type of device, and not to another switch in the network. When Spanguard is enabled, if a non‐loopback BPDU is received on an edge port, the Spanning Tree state of that port will be changed to “blocking” and will no longer forward traffic. The port will remain disabled until the amount of time defined by set spantree spanguardtimeout (“set spantree spanguardtimeout” on page 7‐26) has passed since the last seen BPDU, the port is manually unlocked (set or clear spantree spanguardlock, “clear / set spantree spanguardlock” on page 7‐28), the configuration of the port is changed so it is not longer an edge port, or the SpanGuard function is disabled. SpanGuard is enabled and disabled only on a global basis (across the stack, if applicable). By default, SpanGuard is disabled and SpanGuard traps are enabled. Example This example shows how to enable the SpanGuard function: C2(rw)->set spantree spanguard enable SecureStack C2 Configuration Guide 7-25...

set spantree lp set spantree lp Use this command to enable or disable the Loop Protect feature per port and optionally, per SID. The Loop Protect feature is disabled by default. See “Loop Protect” on page 2. for more information. Syntax set spantree lp port-string {enable | disable} [sid sid] Parameters port‐string Specifies port(s) on which to enable or disable the Loop Protect feature. enable | disable Enables or disables the feature on the specified port. sid sid (Optional) Enables or disables the feature for specific Spanning Tree(s). Valid values are 0 ‐ 4094. If not specified, SID 0 is assumed. Defaults If no SID is specified, SID 0 is assumed. Mode Switch command, read‐write. Usage Loop Protect takes precedence over per port STP enable/disable (portAdmin). Normally portAdmin disabled would cause a port to go immediately to forwarding. If Loop Protect is enabled, that port should go to listening and remain there. Note: The Loop Protect enable/disable settings for an MSTI port should match those for the CIST port.
Parameters port‐string Specifies port(s) for which to clear the Loop Protect feature status. sid sid (Optional) Specifies the specific Spanning Tree(s) for which to clear the Loop Protect feature status. Valid values are 0 ‐ 4094. If not specified, SID 0 is assumed. Defaults If no SID is specified, SID 0 is assumed. Mode Switch command, read‐write. Example This example shows how to return the Loop Protect state on .2.3 to disabled: C2(rw)->clear spantree lp port ge.2.3 show spantree lplock Use this command to display the Loop Protect lock status per port and/or per SID. A port can become locked if a configured number of Loop Protect events occur during the configured window of time. See the set spantree lpthreshold and set spantree lpwindow commands. Once a port is forced into blocking (locked), it remains locked until manually unlocked with the clear spantree lplock command. Syntax show spantree lplock [port port-string] [sid sid] SecureStack C2 Configuration Guide 7-41...
clear spantree lplock Parameters port‐string (Optional) Specifies port(s) for which to display the Loop Protect lock status. sid sid (Optional) Specifies the specific Spanning Tree(s) for which to display the Loop Protect lock status. Valid values are 0 ‐ 4094. If not specified, SID 0 is assumed. Defaults If no port‐string is specified, status is displayed for all ports. If no SID is specified, SID 0 is assumed. Mode Switch command, read‐only. Example This example shows how to display Loop Protect lock status on .1.1: C2(rw)->show spantree lplock port ge.1.1 The LoopProtect lock status for port ge.1.1 , SID 0 is UNLOCKED clear spantree lplock Use this command to manually unlock a blocked port and optionally, per SID. The default state is unlocked.
Mode Switch command, read‐write. Usage The default value for Loop Protect capable partner is false. If the port is configured with a Loop Protect capable partner (true), then the full functionality of the Loop Protect feature is used. If the value is false, then there is some ambiguity as to whether an Active Partner timeout is due to a loop protection event or is a normal situation due to the fact that the partner port does not transmit Alternate Agreement BPDUs. Therefore, a conservative approach is taken in that designated ports will not be allowed to forward unless receiving agreements from a port with root role. This type of timeout will not be considered a loop protection event. Loop protection is maintained by keeping the port from forwarding but since this is not considered a loop event it will not be factored into locking the port. Example This example shows how to set the Loop Protect capable partner to true for .1.1: C2(rw)->set spantree lpcapablepartner ge.1.1 true show spantree lpcapablepartner Use this command to the Loop Protect capability of a link partner for one or more ports. Syntax show spantree lpcapablepartner [port port-string] Parameters port‐string (Optional) Specifies port(s) for which to display Loop Protect capability for its link partner.

Example This example shows how to reset the Loop Protect event threshold to the default of 3: C2(rw)->clear spantree lpthreshold set spantree lpwindow Use this command to set the Loop Protect event window value in seconds. Syntax set spantree lpwindow value Parameters value Specifies the number of seconds that comprise the period during which Loop Protect events are counted. The default event window is 180 seconds. Defaults None. Mode Switch command, read‐write. Usage The Loop Protect Window is a timer value, in seconds, that defines a period during which Loop Protect events are counted. The default value is 180 seconds. If the timer is set to 0, the event counter is not reset until the Loop Protect event threshold is reached. If the threshold is reached, that constitutes a loop protection event. Example This example shows how to set the Loop Protect event window to 120 seconds: C2(rw)->set spantree lpwindow 120 show spantree lpwindow Use this command to display the current Loop Protect event window value.
Use this command to reset the Loop Protect event window to the default value of 180 seconds. Syntax clear spantree lpwindow Parameters None. Defaults None. Mode Switch command, read‐write.

Use this command to set the disputed BPDU threshold, which is the number of disputed BPDUs that must be received on a given port/SID until a disputed BPDU trap is sent. Syntax set spantree disputedbpduthreshold value Parameters value Specifies the number of disputed BPDUs that must be received on a given port/SID to cause a disputed BPDU trap to be sent. A threshold of 0 indicates that traps should not be sent. The default value is 0. Defaults None. Mode Switch command, read‐write. Usage A disputed BPDU is one in which the flags field indicates a designated role and learning, and the priority vector is worse than that already held by the port. If a disputed BPDU is received the port is forced to the listening state. Refer to the 802.1Q‐2005 standard, IEEE Standard for Local and Metropolitan Area Networks – Virtual Bridged Local Area Networks, for a full description of the dispute mechanism, which prevents looping in cases of one‐way communication. The disputed BPDU threshold is an integer variable that represents the number of disputed BPDUs that must be received on a given port/SID until a disputed BPDU trap is sent and a syslog message is issued. For example, if the threshold is 10, then a trap is issued when 10, 20, 30, and so on, disputed BPDUs have been received. If the value is 0, traps are not sent. The trap indicates port, SID and total Disputed BPDU count. The default is 0. Example This example shows how to set the disputed BPDU threshold value to 5: C2(rw)->set spantree disputedbpduthreshold 5 SecureStack C2 Configuration Guide 7-49...

4093. As a default, all ports on the device are assigned to VLAN ID 1, untagged. Port String Syntax Used in the CLI For information on how to designate VLANs and port numbers in the CLI syntax, refer to “Port String Syntax Used in the CLI” on page 5‐2. Creating a Secure Management VLAN By default at startup, there is one VLAN configured on the SecureStack C2 device. It is VLAN ID 1, the DEFAULT VLAN. The default community name, which determines remote access for SNMP management, is set to “public” with read‐write access. SecureStack C2 Configuration Guide 8-1...
Viewing VLANs If the SecureStack C2 device is to be configured for multiple VLANs, it may be desirable to configure a management‐only VLAN. This allows a station connected to the management VLAN to manage the device. It also makes management secure by preventing configuration via ports assigned to other VLANs. To create a secure management VLAN, you must: Step Task Refer to page... Create a new VLAN. Set the PVID for the desired switch port to the VLAN created in Step 1. Add the desired switch port to the egress list for the VLAN created in 8-13 Step 1.
If no options are specified, all information related to static and dynamic VLANs will be displayed. Mode Switch command, read‐only. Example This example shows how to display information for VLAN 1. In this case, VLAN 1 is named “DEFAULT VLAN”. Ports allowed to transmit frames belonging to VLAN 1 are listed as egress ports. Ports that won’t include a VLAN tag in their transmitted frames are listed as untagged ports. There are no forbidden ports (prevented from transmitted frames) on VLAN 1: C2(su)->show vlan 1 VLAN: 1 NAME: DEFAULT VLAN VLAN Type: Default Egress Ports ge.1.1-10, ge.2.1-4, ge.3.1-7, Forbidden Egress Ports None.

clear port vlan Syntax set port vlan port-string pvid [modify-egress | no-modify-egress] Parameters port‐string Specifies the port(s) for which to configure a VLAN identifier. For a detailed description of possible port‐string values, refer to “Port String Syntax Used in the CLI” on page 5‐2. pvid Specifies the VLAN ID of the VLAN to which port(s) will be added. modify‐egress (Optional) Adds port(s) to VLANʹs untagged egress list and removes them from other untagged egress lists. no‐modify‐egress (Optional) Does not prompt for or make egress list changes. Defaults None. Mode Switch command, read‐write. Usage The PVID is used to classify untagged frames as they ingress into a given port. If the specified VLAN has not already been created, this command will create it. It will prompt the user to add the VLAN to the port’s egress list as untagged, and to remove the default VLAN from the port’s egress list. Example This example shows how to add ge.1.10 to the port VLAN list of VLAN 4 (PVID 4). Since VLAN 4 is a new VLAN, it is created. Then port .1.10 is added to VLAN 4’s untagged egress list. The port must then be cleared from the egress list of VLAN 1 (the default VLAN) as shown: C2(su)->set port vlan ge.1.10 4 C2(su)->set vlan 4 create C2(su)->set vlan egress 4 ge.1.10 untagged C2(su)->clear vlan egress 1 ge.1.10...
In this case, the ports are disabled for ingress filtering: C2(su)->show port ingress-filter ge.1.10-15 Port State -------- --------- ge.1.10 disabled ge.1.11 disabled ge.1.12 disabled ge.1.13 disabled ge.1.14 disabled ge.1.15 disabled set port ingress filter Use this command to discard all frames received with a VLAN ID that don’t match the port’s VLAN egress list. Syntax set port ingress-filter port-string {disable | enable} SecureStack C2 Configuration Guide 8-9...
show port discard Parameters port‐string Specifies the port(s) on which to enable of disable ingress filtering. For a detailed description of possible port‐string values, refer to “Port String Syntax Used in the CLI” on page 5‐2. disable | enable Disables or enables ingress filtering. Defaults None. Mode Switch command, read‐write. Usage When ingress filtering is enabled on a port, the VLAN IDs of incoming frames are compared to the port’s egress list. If the received VLAN ID does not match a VLAN ID on the port’s egress list, then the frame is dropped. Ingress filtering is implemented according to the IEEE 802.1Q standard. Example This example shows how to enable port ingress filtering on .1.3: C2(su)->set port ingress-filter ge.1.3 enable show port discard Use this command to display the frame discard mode for one or more ports. Ports can be set to discard frames based on whether or not the frame contains a VLAN tag. They can also be set to discard both tagged and untagged frames, or neither. Syntax show port discard [port-string] Parameters port‐string (Optional) Displays the frame discard mode for specific port(s). For a ...
Parameters port‐string Specifies the port(s) for which to set frame discard mode. For a detailed description of possible port‐string values, refer to “Port String Syntax Used in the CLI” on page 5‐2. tagged | • Tagged ‐ Discard all incoming (received) tagged packets on the defined untagged | both | port(s). none • Untagged ‐ Discard all incoming untagged packets. • Both ‐ All traffic will be discarded (tagged and untagged). • None ‐ No packets will be discarded. Defaults None. Mode Switch command, read‐write. Usage The options are to discard all incoming tagged frames, all incoming untagged frames, neither (essentially allow all traffic), or both (essentially discarding all traffic). A common practice is to discard all tagged packet on user ports. Typically an Administrator does not want the end users defining what VLAN they use for communication. Example This example shows how to discard all tagged frames received on port .3.3: C2(su)->set port discard ge.3.3 tagged SecureStack C2 Configuration Guide 8-11...
Configuring the VLAN Egress List Configuring the VLAN Egress List Purpose To assign or remove ports on the egress list of a particular VLAN. This determines which ports on the switch will be eligible to transmit frames for a particular VLAN. For example, ports 1, 5, 7, 8 could be allowed to transmit frames belonging to VLAN 20 and ports 7,8, 9, 10 could be allowed to transmit frames tagged with VLAN 30 (a port can belong to multiple VLAN Egress lists). Note that the Port Egress list for ports 7 and 8 would contain both VLAN 20 and 30. The port egress type for all ports can be set to tagged, forbidden, or untagged. In general, VLANs have no egress (except for VLAN 1) until they are configured by static administration, or through dynamic mechanisms such as GVRP. Setting a port to forbidden prevents it from participating in the specified VLAN and ensures that any dynamic requests (either through GVRP or dynamic egress) for the port to join the VLAN will be ignored. Setting a port to untagged allows it to transmit frames without a tag header. This setting is usually used to configure a port connected to an end user device. Frames sent between VLAN aware switches are typically tagged. The default VLAN defaults its egress to untagged for all ports. Commands For information about... Refer to page... show port egress 8-12 set vlan forbidden 8-13 set vlan egress 8-13 clear vlan egress...
Use this command to prevent one or more ports from participating in a VLAN. This setting instructs the device to ignore dynamic requests (either through GVRP or dynamic egress) for the port to join the VLAN. Syntax set vlan forbidden vlan-id port-string Parameters vlan‐id Specifies the VLAN for which to set forbidden port(s). port‐string Specifies the port(s) to set as forbidden for the specified vlan‐id. Defaults None. Mode Switch command, read‐write. Example This example shows you how to set .1.3 to forbidden for VLAN 6: C2(su)->set vlan forbidden 6 ge.1.3 set vlan egress Use this command to add ports to the VLAN egress list for the device, or to prevent one or more ports from participating in a VLAN. This determines which ports will transmit frames for a particular VLAN. SecureStack C2 Configuration Guide 8-13...

Syntax set host vlan vlan-id Parameters vlan‐id Specifies the number of the VLAN to set as the host VLAN. Defaults None. SecureStack C2 Configuration Guide 8-17...
clear host vlan Mode Switch command, read‐write. Usage The host VLAN should be a secure VLAN where only designated users are allowed access. For example, a host VLAN could be specifically created for device management. This would allow a management station connected to the management VLAN to manage all ports on the device and make management secure by preventing management via ports assigned to other VLANs. Note: Before you can designate a VLAN as the host VLAN, you must create a VLAN using the set of commands described in “Creating and Naming Static VLANs” on page 8-4. Example This example shows how to set VLAN 7 as the host VLAN: C2(su)->set host vlan 7...

The SecureStack C2 supports Class of Service (CoS), which allows you to assign mission‐critical ...
Configuring Policy Class of Service (CoS) Enterasys Networks’ enhanced CoS implementation allows you to use the following methods to configure Class of Service on the SecureStack C2: • Allowing the switch to automatically assign policy‐based inbound rate limiters as described in this section. • Configuring transmit queueing and rate limiting on a per‐port basis as described in Chapter By default, policy‐based CoS is disabled on the device, and default or user‐assigned port‐based 802.1D (802.1p) settings are used to determine traffic rate limiting. When policy‐based CoS is enabled, the default and user‐assigned policy‐based settings will override port‐based settings described in Chapter About Policy-Based CoS Configurations Once enabled using the set cos state command as described in “set cos state” on page 9‐18, you can add to the policy‐based CoS function by defining new port groupings, and assigning inbound rate limiters.

show cos reference rate‐limit irl‐index Rate limiter (IRL resource index) to bind this reference to. Valid values range from 0 to 99. Defaults None. Mode Switch command, read‐write. Usage The CoS reference table maps the user‐defined IRL references found in the CoS settings table (see “set cos settings” on page 9‐20) to rate limiters created in the port resource table (see “set cos port‐ resource” on page 9‐25). The CoS reference table indexes can be thought of as virtual rate limiters. The table accounts for the maximum number of rate limiters supported by the device. The virtual limiters then map to the physical rate limiters. The CoS IRL Reference Table is not configured by default. The CoS IRL reference table uses 100 indexes or virtual rate limiters, and maps each virtual limiter to a physical limiter or resource. An IRL reference table exists for each port group configured, and is indexed similarly to port resources, as port group#, port‐type, reference. IRL references are not populated with limiters (resources), but can be configured by the user. The IRL reference table can be displayed using the show cos reference command. Example In the CoS IRL reference mapping table for port groups 1.0 and 2.0, create a reference for the IRL resource number 1 created for each group. The reference number 1 is used. C2(su)->set cos reference irl 1.0 1 rate-limit 1 C2(su)->set cos reference irl 2.0 1 rate-limit 1 show cos reference Use this command to show the Class of Service inbound rate limiting reference configuration.

--- --- --- --- --- --- --- --- --- ge.1.1 WRR 2 Configuring Port Traffic Rate Limiting Purpose To limit the rate of inbound traffic on the SecureStack C2 device on a per port/priority basis. The allowable range for the rate limiting is 64 kilobytes per second minimum up to the maximum transmission rate allowable on the interface type. Rate limit is configured for a given port and list of priorities. The list of priorities can include one, some, or all of the eight 802.1p priority levels. Once configured, the rate of all traffic entering the port with the priorities configured to that port is not allowed to exceed the programmed limit. If the rate exceeds the programmed limit, frames are dropped until the rate falls below the limit. Note: Port traffic rate limiting is not supported on mixed stacks containing B3 or C3 devices.

Configuring IGMP on Routing Interfaces 11-9 IGMP Overview About IP Multicast Group Management The Internet Group Management Protocol (IGMP) runs between hosts and their immediately neighboring multicast device. The protocol’s mechanisms allow a host to inform its local device that it wants to receive transmissions addressed to a specific multicast group. A multicast‐enabled device can periodically ask its hosts if they want to receive multicast traffic. If there is more than one device on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the responsibility of querying the LAN for group members. Based on the group membership information learned from IGMP, a device can determine which (if any) multicast traffic needs to be forwarded to each of its ports. At Layer‐3, multicast devices use this information, along with a multicast routing protocol, to support IP multicasting across the Internet. IGMP provides the final step in an IP multicast packet delivery service, since it is only concerned with forwarding multicast traffic from the local device to group members on a directly attached subnetwork or LAN segment. This device supports IP multicast group management by passively snooping on the IGMP query and IGMP report packets transferred between IP multicast devices and IP multicast host groups to learn IP multicast group members. The purpose of IP multicast group management is to optimize a switched network’s performance so multicast packets will only be forwarded to those ports containing multicast group hosts or multicast devices instead of flooding to all ports in the subnet (VLAN). In addition to passively monitoring IGMP query and report messages, the SecureStack C2 can also actively send IGMP query messages to learn locations of multicast devices and member hosts in multicast groups within each VLAN. However, note that IGMP neither alters nor routes any IP multicast packets. Since IGMP is not concerned with the delivery of IP multicast packets across subnetworks, an external IP multicast device is needed if IP multicast packets have to be routed across different subnetworks. SecureStack C2 Configuration Guide 11-1...
Configuring IGMP at Layer 2 About Multicasting Multicasting is used to support real‐time applications such as video conferences or streaming audio. A multicast server does not have to establish a separate connection with each client. It merely broadcasts its service to the network, and any hosts that want to receive the multicast register with their local multicast switch/router. Although this approach reduces the network overhead required by a multicast server, the broadcast traffic must be carefully pruned at every multicast switch/router it passes through to ensure that traffic is only passed to the hosts that subscribed to this service. The SecureStack C2 switch device uses IGMP (Internet Group Management Protocol) to query for any attached hosts who want to receive a specific multicast service. The device looks up the IP Multicast Group used for this service and adds any port that received a similar request to that group. It then propagates the service request on to any neighboring multicast switch/router to ensure that it will continue to receive the multicast service. Configuring IGMP at Layer 2 Purpose To configure IGMP snooping from the switch CLI. Commands For information about...

Configuring IP Address Pools 14-11 DHCP Overview Dynamic Host Configuration Protocol (DHCP) for IPv4 is a network layer protocol that implements automatic or manual assignment of IP addresses and other configuration information to client devices by servers. A DHCP server manages a user‐configured pool of IP addresses from which it can make assignments upon client requests. A relay agent passes DHCP messages between clients and servers which are on different physical subnets. DHCP Relay Agent The DHCP/BOOTP relay agent function can be configured on all of the SecureStack C2’s routing interfaces. The relay agent can forward a DHCP client’s request to a DHCP server located on a different network if the address of the server is configured as a helper address on the receiving interface. The relay agent interface must be a VLAN which is configured with an IP address. Refer to the ip helper‐address command (“ip helper‐address” on page 16‐12) for more information. DHCP Server DHCP server functionality allows the SecureStack C2 switch to provide basic IP configuration information to a client on the network who requests such information using the DHCP protocol. DHCP provides the following mechanisms for IP address allocation by a DHCP server: • Automatic—DHCP server assigns an IP address to a client for a limited period of time (or until the client explicitly relinquishes the address) from a defined pool of IP addresses configured on the server. • Manual—A client’s IP address is assigned by the network administrator, and DHCP is used simply to convey the assigned address to the client. This is managed by means of “static” address pools configured on the server. The amount of time that a particular IP address is valid for a system is called a lease. The SecureStack C2 maintains a lease database which contains information about each assigned IP SecureStack C2 Configuration Guide 14-1...
• Default router(s) • DNS server(s) and domain name • NetBIOS WINS server(s) and node name • Boot file • DHCP options as defined by RFC 2132 Note: A total of 16 address pools, dynamic and/or static, can be configured on the SecureStack C2 Configuring a DHCP Server On the C2, there are two ways to configure a DHCP server: one is to associate the DHCP address pool with the switch’s host port IP address, and the other is to associate the DHCP address pool with a routed interface. Since on a C2 system, the host port IP address cannot fall within a configured routed interface on the system, a typical C2 system configured with routing interfaces will not have a host port IP address. Therefore, all DHCP pools would be associated with routed interfaces. The following tasks provide basic DHCP server functionality when the DHCP pool is associated with the system’s host IP address. This procedure would typically be used when the C2 system is NOT configured for routing. ...

Syntax ip directed-broadcast no ip directed-broadcast Parameters None. SecureStack C2 Configuration Guide 16-11...
ip helper-address Defaults None. Mode Interface configuration: C2(su)‐>Router1(Config‐if(Vlan 1))# Usage Directed broadcast is an efficient mechanism for communicating with multiple hosts on a network while only transmitting a single datagram. A directed broadcast is a packet sent to all hosts on a specific network or subnet. The directed broadcast address includes the network or subnet fields, with the binary bits of the host portion of the address set to one. For example, for a network with the address 192.168.0.0, the directed broadcast address would be 192.168.255.255. For a subnet with the address 192.168.12.0, the directed broadcast address would be 192.168.12.255. In order to minimize broadcast DoS attacks, forwarding of directed broadcasts is disabled by default on the SecureStack C2, as recommended by RFC 2644. If the ability to send directed broadcasts to a network is required, you should enable directed broadcasts only on the one interface that will be transmitting the datagrams. For example, if a SecureStack C2 has five routed interfaces for the 10, 20, 30, 40, and 50 networks, enabling directed broadcast only on the 30 network interface will allow anyone from any other networks (10, 20, 40, 50) to send directed broadcast to the 30 network. Example This example shows how to enable IP directed broadcasts on VLAN 1: C2(su)->router(Config)#interface vlan 1 C2(su)->router(Config-if(Vlan 1))#ip directed-broadcast ip helper-address Use this command to enable the DHCP/BOOTP relay agent on a SecureStack C2 routed interface. Enabling the relay agent allows forwarding of client DHCP/BOOTP requests to a DHCP/BOOTP server that does not reside on the same broadcast domain as the client. Up to 6 IP helper addresses may be configured per interface. The no form of this command disables the forwarding of UDP datagrams to the specified address. Syntax ip helper-address address no ip helper-address address Parameters address Address of the host where UDP broadcast packets should be forwarded.

Configuring Access Lists 18-70 Overview of Security Methods The following security methods are available for controlling which users are allowed to access, monitor, and manage the switch. • Login user accounts and passwords – used to log in to the CLI via a Telnet connection or local COM port connection. For details, refer to “Setting User Accounts and Passwords” on page 3‐1. • Host Access Control Authentication (HACA) – authenticates user access of Telnet management, console local management and WebView via a central RADIUS Client/Server application. When RADIUS is enabled, this essentially overrides login user accounts. When HACA is active per a valid RADIUS configuration, the user names and passwords used to access the switch via Telnet, SSH, WebView, and COM ports will be validated against the configured RADIUS server. Only in the case of a RADIUS timeout will those credentials be compared against credentials locally configured on the switch. For details, refer to “Configuring RADIUS” on page 18‐3. • SNMP user or community names – allows access to the SecureStack C2 switch via a network SNMP management application. To access the switch, you must enter an SNMP user or community name string. The level of management access is dependent on the associated access policy. For details, refer to Chapter • 802.1X Port Based Network Access Control using EAPOL (Extensible Authentication Protocol) – provides a mechanism via a RADIUS server for administrators to securely SecureStack C2 Configuration Guide 18-1...

Note: To configure EAP pass-through, which allows client authentication packets to be forwarded through the switch to an upstream device, 802.1X authentication must be globally disabled with the set dot1x command. • MAC Authentication – provides a mechanism for administrators to securely authenticate ...
• To specify both management level and policy profile: Enterasys:version=1:mgmt=level:policy=string The undecorated format is simply a string that specifies a policy profile name. The undecorated format cannot be used for management access authentication. Decorated Filter‐IDs are processed first by the switch. If no decorated Filter‐IDs are found, then undecorated Filter‐IDs are processed. If multiple Filter‐IDs are found that contain conflicting values, a Syslog message is generated. Configuring RADIUS Purpose To perform the following: • Review the RADIUS client/server configuration on the switch. • Enable or disable the RADIUS client. • Set local and remote login options. • Set primary and secondary server parameters, including IP address, timeout period, authentication realm, and number of user login attempts allowed. • Reset RADIUS server settings to default values. • Configure a RADIUS accounting server.

set radius realm Realm allows you to define who has to go through the RADIUS server for management‐ authentication. access | any | • management‐access: This means that anyone trying to access the switch network‐access (Telnet, SSH, Local Management) has to authenticate through the RADIUS server. • network‐access: This means that all the users have to authenticate to a RADIUS server before they are allowed access to the network. • any: Means that both management‐access and network‐access have been enabled. Note: If the management-access or any access realm has been configured, the local “admin” account is disabled for access to the switch using the console, Telnet, or Local Management.

Usage Changing the Reauth Period with the set macauthentication reauthperiod command does not affect current sessions. New sessions will use the correct period. Example This example shows how to set the MAC reauthentication period to 7200 seconds (2 hours) on .2.1 through 5: C2(su)->set macauthentication reauthperiod 7200 ge.2.1-5 clear macauthentication reauthperiod Use this command to clear the MAC reauthentication period on one or more ports.
Parameters number Specifies the number of significant bits to be used for authentication. Defaults None. Mode Switch command, read‐write. Usage This command allows you to specify a mask to apply to MAC addresses when authenticating users through a RADIUS server. The most common use of significant bit masks is for authentication of all MAC addresses for a specific vendor. On switches using MAC authentication, the MAC address of a user attempting to log in is sent to the RADIUS server as the user name. If access is denied, and if a significant bit mask has been configured (other than 48) with this command, the switch will apply the mask and resend the masked address to the RADIUS server. For example, if a user with MAC address of 00‐16‐CF‐12‐ 34‐56 is denied access, and a 32 bit mask has been configured, the switch will apply the mask and resend a MAC address of 00‐16‐CF‐12‐00‐00 to the RADIUS server. To use a significant bits mask for authentication of devices by a particular vendor, specify a 24‐bit mask, to mask out everything except the vendor portion of the MAC address. Example This example sets the MAC authentication significant bits mask to 24. C2(su)->set macauthentication significant-bits 24 clear macauthentication significant-bits Use this command to reset the number of significant bits of the MAC address to use for authentication to the default of 48. Syntax clear macauthentication significant-bits SecureStack C2 Configuration Guide 18-29...
Configuring Multiple Authentication Methods Parameters None. Defaults None. Mode Switch command, read‐write. Example This example resets the MAC authentication significant bits to 48. C2(su)->clear macauthentication significant-bits Configuring Multiple Authentication Methods Note: C2 devices support up to eight authenticated users per port. About Multiple Authentication Types When enabled, multiple authentication types allow users to authenticate using up to two methods on the same port. In order for multiple authentication to function on the device, each possible method of authentication (MAC authentication, 802.1X, PWA) must be enabled globally and configured appropriately on the desired ports with its corresponding command set described in this chapter. Multiple authentication mode must be globally enabled on the device using the set multiauth mode command.

Up to six users can be configured per Gigabit port. Please see section 3‐31 of RFC 3580 for details on configuring a RADIUS server to return the desired tunnel attributes. As stated in RFC 3580, “... it may be desirable to allow a port to be placed into a particular Virtual LAN (VLAN), defined in [IEEE8021Q], based on the result of the authentication.” The RADIUS server typically indicates the desired VLAN by including tunnel attributes within its Access‐Accept parameters. However, the IEEE 802.1X authenticator can also be configured to instruct the VLAN to be assigned to the supplicant by including tunnel attributes within Access‐ Request parameters. The following tunnel attributes are used in VLAN authorization assignment, : • Tunnel‐Type ‐ VLAN (13) • Tunnel‐Medium‐Type ‐ 802 • Tunnel‐Private‐Group‐ID ‐ VLANID SecureStack C2 Configuration Guide 18-41...
