This switch provides a broad range of features for Layer 2 switching. It includes a management agent that allows you to configure the features listed in this manual. The default configuration can be used for most of the features provided by this switch. However, there are many options that you should configure to maximize the switch’s performance for your particular...
Page 28: Description Of Software Features
Multicast Filtering Supports IGMP snooping and query Description of Software Features The switch provides a wide range of advanced performance enhancing features. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Broadcast storm suppression prevents broadcast traffic storms from engulfing the network.
Page 29 Use the full-duplex mode on ports whenever possible to double the throughput of switch connections. Flow control should also be enabled to control network traffic during periods of congestion and prevent the loss of packets when port buffer thresholds are exceeded.
Page 30 Static Addresses – A static address can be assigned to a specific interface on this switch. Static addresses are bound to the assigned interface and will not be moved. When a static address is seen on another interface, the address will be ignored and will not be written to the address table.
Page 31 ESCRIPTION OF OFTWARE EATURES To avoid dropping frames on congested ports, the switch provides 1 MB for frame buffering. This buffer can queue packets awaiting transmission on congested networks. Spanning Tree Protocol – The switch supports these spanning tree protocols: Spanning Tree Protocol (STP, IEEE 802.1D) –...
Page 32 NTRODUCTION Virtual LANs – The switch supports up to 255 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. The switch supports tagged VLANs based on the IEEE 802.1Q standard.
Page 33: System Defaults
System Defaults The switch’s system defaults are provided in the configuration file “Factory_Default_Config.cfg.” To reset the switch defaults, this file should be set as the startup configuration file (page 3-25). The following table lists some of the basic system defaults.

Page 41: Setting Passwords
Access to both CLI levels are controlled by user names and passwords. The switch has a default user name and password for each level. To log into the CLI at the Privileged Exec level using the default user name and password, perform these steps: 1.
Page 42: Setting An Ip Address
DHCP address allocation servers on the network. Manual Configuration You can manually assign an IP address to the switch. You may also need to specify a default gateway that resides between this device and management stations on another network segment. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.
Page 43: Dynamic Configuration
Before you can assign an IP address to the switch, you must obtain the following information from your network administrator: • IP address for the switch • Default gateway for the network • Network mask for this network To assign an IP address to the switch, complete the following steps: 1.

Page 45: Enabling Snmp Management Access
The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as SMC EliteView. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP traps. When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter.
Page 46 If there are no community strings, then SNMP management access to the switch is disabled. To prevent unauthorized access to the switch via SNMP, it is recommended that you change the default community strings. To configure a community string, complete the following steps: 1.
Page 47: Trap Receivers
“community-string” is the string associated with that host. Press <Enter>. 2. In order to configure the switch to send SNMP notifications, you must enter at least one snmp-server enable traps command. Type “snmp-server enable traps type,” where “type” is either authentication or link-up-down.
Page 48: Managing System Files
Diagnostic Code — Software that is run during system boot-up, also known as POST (Power On Self-Test). Due to the size limit of the flash memory, the switch supports only two operation code files. However, you can have as many diagnostic code files and configuration files as available flash memory space allows.
Page 49 ANAGING YSTEM ILES Note that configuration files should be downloaded using a file name that reflects the contents or usage of the file settings. If you download directly to the running-config, the system will reboot, and the settings will have to be copied from the running-config to a permanent file.

Page 119: Configuring Acl Masks
Configuring ACL Masks You must specify masks that control the order in which ACL rules are checked. The switch includes two system default masks that pass/filter packets matching the permit/deny rules specified in an ingress ACL. You must also configure up to seven user-defined masks for an ingress or egress ACL.

Page 194 VLAN Classification – When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN (based on the default VLAN ID of the receiving port).
Page 195 IEEE 802.1Q VLAN protocol, it can be configured to broadcast a message to your network indicating the VLAN groups it wants to join. When this switch receives these messages, it will automatically place the receiving port in the specified VLANs, and then forward the message to all other ports.

• When a frame enters a port that has been assigned to a protocol VLAN, it is processed in the following manner: - If the frame is tagged, it will be processed according to the standard rules applied to tagged frames. - If the frame is untagged and the protocol type matches, the frame is forwarded to the appropriate VLAN.
Page 214: Class Of Service Configuration
Layer 2 Queue Settings Setting the Default Priority for Interfaces You can specify the default port priority for each interface on the switch. All untagged packets entering the switch are tagged with the specified default port priority, and then sorted into the appropriate priority queue at the output port.
Page 215: Figure 3-70 Default Port Priority
Command Attributes • Default Priority received on the specified interface. (Range: 0 - 7, Default: 0) • Number of Egress Traffic Classes – The number of queue buffers provided for each port. Web – Click Priority, Default Port Priority or Default Trunk Priority. Modify the default priority for any interface, then click Apply.

Page 218: Selecting The Queue Mode
WITCH Selecting the Queue Mode You can set the switch to service the queues based on a strict rule that requires all traffic in a higher priority queue to be processed before lower priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue.
Page 219: Setting The Service Weight For Traffic Classes
Setting the Service Weight for Traffic Classes This switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue. As described in “Mapping CoS Values to Egress Queues” on page 3-166, the traffic classes are mapped to one of the eight egress queues provided for each port.
Page 220: Layer 3/4 Priority Settings
Because different priority information may be contained in the traffic, this switch maps priority values to the output queues in the following manner: • The precedence for priority mapping is IP Port Priority, IP Precedence or DSCP Priority, and then Default Port Priority.
Page 221: Selecting Ip Precedence/Dscp Priority
Selecting IP Precedence/DSCP Priority The switch allows you to choose between using IP Precedence or DSCP priority. Select one of the methods or disable this feature. Command Attributes • Disabled – Disables both priority services. (This is the default setting.) •...
Page 222: Mapping Ip Precedence
ONFIGURING THE WITCH Mapping IP Precedence The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight different priority levels ranging from highest priority for network control packets to lowest priority for routine traffic. The default IP Precedence values are mapped one-to-one to Class of Service values (i.e., Precedence value 0 maps to CoS value 0, and so forth).
Page 223: Figure 3-75 Ip Precedence Priority

Compared to standard Ethernet frames that run only up to 1.5 KB, using jumbo frames significantly reduces the per-packet overhead required to process protocol encapsulation fields.
Page 334: Copy
This command moves (upload/download) a code image or configuration file between the switch’s flash memory and a TFTP server. When you save the system code or configuration settings to a file on a TFTP server, that file can later be downloaded to the switch to restore system operation. The success of the file transfer depends on the accessibility of the TFTP server and the quality of the network connection.
Page 335 31 characters for files on the switch. (Valid characters: A-Z, a-z, 0-9, “.”, “-”, “_”) • Due to the size limit of the flash memory, the switch supports only two operation code files. • The maximum number of user-defined configuration files depends on available memory.

Page 363: Access Control List Commands
An ACL is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress or egress packets against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon as it matches a deny rule.
Page 364 • The switch does not support the explicit “deny any any” rule for the egress IP ACL or the egress MAC ACLs. If these rules are included in an ACL, and you attempt to bind the ACL to an interface for egress checking, the bind operation will fail.
Page 365: Ip Acls
Masks for Access Control Lists You can specify optional masks that control the order in which ACL rules are checked. The switch includes two system default masks that pass/filter packets matching the permit/deny rules specified in an ingress ACL. You can also configure up to seven user-defined masks for an ACL.

Page 434: Link Aggregation Commands
For static trunks, the switches have to comply with the Cisco EtherChannel standard. For dynamic trunks, the switches have to comply with LACP. This switch supports up to six trunks. For example, a trunk consisting of two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when operating at full duplex.
Page 435: Guidelines For Creating Trunks
Guidelines for Creating Trunks General Guidelines • Finish configuring port trunks before you connect the corresponding network cables between switches to avoid creating a loop. • A trunk can have up to eight ports. • The ports at both ends of a connection must be configured as trunk ports.
Page 436: Channel-Group
• When configuring static trunks, the switches must comply with the Cisco EtherChannel standard. • Use no channel-group to remove a port group from a trunk. • Use no interfaces port-channel to remove a trunk from the switch. Example The following example creates trunk 1 and then adds port 11.
Page 437 • A trunk formed with another switch using LACP will automatically be assigned the next available port-channel ID. • If the target switch has also enabled LACP on the connected ports, the trunk will be activated automatically. • If more than four ports attached to the same target switch have LACP enabled, the additional ports will be placed in standby mode, and will only be enabled if one of the active links fails.
Page 438 OMMAND NTERFACE Example The following shows LACP enabled on ports 10-12. Because LACP has also been enabled on the ports at the other end of the links, the show interfaces status port-channel 1 command shows that Trunk1 has been established. Console(config)#interface ethernet 1/10 Console(config-if)#lacp Console(config-if)#exit...
Page 439: Lacp System-Priority

Page 465: Name
• You can set this switch to act as the MSTI root device by specifying a priority of 0, or as the MSTI alternate device by specifying a priority of 16384. Example Console(config-mstp)#mst 1 priority 4096 Console(config-mstp)# name This command configures the name for the multiple spanning tree region in which this switch is located.
Page 466: Revision
The MST region name (page 4-217) and revision number are used to designate a unique MST region. A bridge (i.e., spanning-tree compliant device such as this switch) can only belong to one MST region. And all bridges in the same region must be configured with the same MST instances.
Page 467: Spanning-Tree Spanning-Disabled
Default Setting Command Mode MST Configuration Command Usage A MSTI region is treated as a single node by the STP and RSTP protocols. Therefore, the message age for BPDUs inside a MSTI region is never changed. However, each spanning tree instance within a region, and the internal spanning tree (IST) that connects these instances use a hop count to specify the maximum number of bridges that will propagate a BPDU.

Console(config)#interface ethernet 1/1 Console(config-if)#switchport forbidden vlan add 3 Console(config-if)# Displaying VLAN Information Command show vlan show interfaces status vlan show interfaces switchport show vlan This command shows VLAN information.
Page 490: Configuring Protocol-Based Vlans
VLANs, including security and easy accessibility. To avoid these problems, you can configure this switch with protocol-based VLANs that divide the physical network into logical VLAN groups for each required protocol. When a frame is received at a port, its VLAN membership can then be determined based on the protocol type in use by the inbound packets.
Page 491: Protocol-Vlan Protocol-Group (Configuring Groups)
To configure protocol-based VLANs, follow these steps: 1. First configure VLAN groups for the protocols you want to use (page -233). Although not mandatory, we suggest configuring a separate VLAN for each major protocol running on your network. Do not add port members at this time. 2.
Page 492: Protocol-Vlan Protocol-Group (Configuring Interfaces)
OMMAND NTERFACE Example The following creates protocol group 1, and specifies Ethernet frames with IP and ARP protocol types. Console(config)#protocol-vlan protocol-group 1 add frame_type ethernet protocol-type ip Console(config)#protocol-vlan protocol-group 1 add frame_type ethernet protocol-type arp Console(config)# protocol-vlan protocol-group (Configuring Interfaces) This command maps a protocol group to a VLAN for the current interface.
Page 493: Show Protocol-Vlan Protocol-Group
• When a frame enters a port that has been assigned to a protocol VLAN, it is processed in the following manner: - If the frame is tagged, it will be processed according to the standard rules applied to tagged frames. - If the frame is untagged and the protocol type matches, the frame is forwarded to the appropriate VLAN.

Page 519: Multicast Filtering Commands
Multicast Filtering Commands This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts that want to receive a specific multicast service. It identifies the ports containing hosts requesting a service and sends data out to those ports only. It then propagates the service request up to any neighboring multicast switch/router to ensure that it will continue to receive the multicast service.

Page 550 LOSSARY User Datagram Protocol (UDP) provides a datagram mode for packet-switched communications. It uses IP as the underlying transport mechanism to provide access to IP-like services. UDP packets are delivered just like IP packets – connection-less datagrams that may be discarded before reaching their targets. UDP is useful when TCP would be too complex, too slow, or just unnecessary.
