Page 60 Overview of Security Methods When the Radius Client is active on the switch module, the user is presented with an authorization screen, prompting for a user login name and password when attempting to access the host IP address via the local console LM, Telnet to LM, or WebView application. The embedded Radius Client encrypts the information entered by the user and sends it to the Radius Server for validation.
Page 61: Authentication Terms And Abbreviations
When configured in conjunction with NetSight Policy Manager and Radius server(s), Enterasys Networks’ switch modules can dynamically administer user based policy that is specifically tailored to the end user’s needs.
Page 62: Security Overview
Authenticators reside in edge switches. They shuffle messages and tell the switch when to grant or deny access, but do not validate logins. User validation is the job of authentication servers. This separation of functions allows network managers to put authentication servers on central servers.
Page 63: Mac Authentication Overview
If the string exists and it refers to a currently configured policy in this switch, then the port receives this new policy. If authenticated, but the authorized policy is invalid or non-existent, then the port forwards the frame normally according to the port default policy, if one exists.
Page 64: Authentication
If a switch port is configured to enable both 802.1X and MAC Authentication, then it is possible for the switch to receive a start or a response 802.1X frame while a MAC Authentication is in progress. If this situation, the switch immediately aborts MAC Authentication. The 802.1X authentication then proceeds to completion.

Page 188: Link Aggregation Screen (802.3Ad Main Menu Screen)
In normal usage (and typical implementations) there is no need to modify any of these parameters. The default values will result in the maximum number of aggregations possible. If the switch is placed in a configuration with its peers not running the protocol, no aggregations will be formed and the switch will function normally (that is, will block redundant paths).
Page 189 Spanning Tree When multiple links are connected from one switch to another, it is necessary that only one link be allowed to switch network traffic. Due to the functionality of a switch, if multiple links were active, a packet would end up “looping” around in those links indefinitely. This problem is well documented and is the reason that bridges implement the Spanning Tree Protocol (STP).
Page 190 Link Aggregation Screen (802.3ad Main Menu Screen) The STP is able to calculate which ports on a switch can be allowed to forward traffic to eliminate the possibility of looping in a network. So, if multiple links were attached between two switches, only one would be used.
Page 191 Most switch vendors provide a way to group these ports together manually. For example, the user could configure Ports 1, 2 and 3 in a trunk on switch X and connect to ports 4, 5 and 6 that are in a trunk on switch Y.

Page 295: About The Ip Tos Rewrite Feature
Figure 9-7 Datagram, Layer 2 and Layer 3 This IP TOS Rewrite feature enables a Network Administrator to assign Layer 3 TOS characteristics to incoming frames and set the switch to rewrite the 8-bit TOS value in the Layer 3 information portion of incoming frames.
Page 296: Displaying The Current Pid/Classification Assignments
Priority Classification Configuration Screen The IP TOS Rewrite feature enables you to configure the switch to: • Insert a user-defined 8-bit value into the layer-3 TOS field. • Write over an existing TOS value. This is useful when the Network Administrator wants to enforce a specific priority policy in the network.

Page 310: More About Rate Limiting
Assume that a network was built using a 6C105 chassis in each closet and interconnected with Enterasys Networks switch routers using Gigabit Ethernet links. Also, assume that 100 users are attached to each 6C105 chassis through 100 Mbps Ethernet ports. If each user attempted to transfer data out of the wiring closet at the maximum possible rate, there could be up to 10 Gbps (100 users x 100 Mbps) of traffic attempting to leave the chassis over a single gigabit link.
Page 311 Rate Limiting Configuration Screen To solve this problem, the Rate Limiting feature can be configured on each port to provide each user with 5 Mbps of high priority bandwidth into the fabric. Now the maximum possible amount of traffic attempting to leave the chassis at high priority is 5 x 100 = 500 Mbps. The gigabit link has ample capacity to carry this load out of the chassis.

Page 380: Defining Vlans
Defining VLANs 13.1 DEFINING VLANs A Virtual Local Area Network is a group of devices that function as a single Local Area Network segment (broadcast domain). The devices that make up a particular VLAN may be widely separated, both by geography and location in the network. The creation of VLANs allows users located in separate areas or connected to separate ports to belong to a single VLAN group.
Page 381: Example Of A Vlan
SmartSwitch A, cross the high speed link to SmartSwitch B, and then propagated out all switch ports on SmartSwitch B. The SmartSwitches treat each port as being equivalent to any other port, and have no understanding of the departmental memberships of each workstation.
Page 382: Types Of Vlans
FDB ID cannot communicate with the members of another FDB ID. To set up a VLAN, all the network switch devices that are assigned to the VLAN must support the IEEE 802.1Q specification for VLANs. Before you attempt to implement a VLAN strategy, ensure that the switches under consideration support the IEEE 802.1Q specification.
Page 383: Vlan Terms And Definitions
13.4 VLAN TERMS To fully understand the operation and configuration of port based VLANs, it is essential to understand the definitions of several key terms. Table 13-1 VLAN Terms and Definitions VLAN Term VLAN ID VLAN Name Egress Ingress Filtering Database Identifier (FDB ID) Tag Header (VLAN Tag) Tagged Frame...
Page 384 The port will drop all incoming frames that do not have a VLAN tag. This is a reference to a connection from a switch that passes only untagged traffic. By default, a port designated to pass only untagged frames has all VLANs on its Port VLAN List and is configured to transmit all frames as untagged frames.
Page 385: Vlan Operation
The 802.1Q VLAN operation is slightly different than the operation of traditional switched networking systems. These differences are due to the importance of keeping track of each frame and its VLAN association as it passes from switch to switch or from port to port within a switch. 13.5.2 VLAN Components Before describing the operation of an 802.1Q VLAN, it is important to understand the basic...
Page 386: Configuration Process
Before a VLAN can operate, steps must be performed to configure the switch to establish and configure a VLAN. Enterasys Networks VLAN-aware switches default to operate in the 802.1Q VLAN mode. However, further configuration is necessary to establish multiple logical networks.
Page 387: Vlan Switch Operation
These VLAN tags are added to data frames by the switch as the frames are transmitted out certain ports, and are later used to make forwarding decisions by the switch and other VLAN-aware switches. In the absence of a VLAN tag header, the classification of a frame into a particular VLAN depends upon the configuration of the switch port that received the frame.
Page 388: Receiving Frames From Vlan Ports
The switch receives a frame from Port 1 and examines the frame. The switch notices that this frame does not currently have a VLAN tag. The switch recognizes that Port 1 is a member of VLAN A and classifies the frame as such. In this fashion, all untagged frames entering a VLAN switch assume membership in a VLAN.
Page 389: Known Unicasts
When the switch is powered up, the switch uses its default settings to switch frames like an 802.1Q switch. In this default configuration, all ports are a member of the default VLAN (VLAN 1) including the virtual Host Data Port of the switch, so any port can be used to manage the device as shown in Figure 13-3.
Page 390: Switch With Vlans
Figure 13-3 Switch Management with Only Default VLAN 13.8.3 Switch with VLANs If the switch is to be configured for multiple VLANs, it may be desirable to configure a management-only VLAN. This allows a management station connected to the management VLAN to manage all ports on the switch and make management secure by preventing management via ports assigned to other VLANs.

VLAN” (or other suitable name) and its VLAN ID. In this example, the VLAN ID is set to 2. An FDB ID is automatically assigned by the switch, so that the Management VLAN has its filtering database to make the VLAN secure. In this example, the FDB ID is 2 and no other VLAN is assigned to this FDB ID.
Page 392: Summary Of Vlan Local Management
No matter how many switches are connected, a management station connected to any port on the same Management VLAN can be used to remotely manage any Enterasys Networks 802.1Q switch in the network as long as the Host Data Port of all the switches are members of the same Management VLAN.

2. Use the arrow keys to highlight the Egress field of Port 3. NOTE: For the purposes of this walkthrough, Port 3 will be configured. As this port will connect to a single workstation, and is not to be used for switch-to-switch communications, the Egress will be set to UNTAGGED.
Page 396: Walkthrough Stage Two, Port 3 Egress Setting
Now that Port 3 belongs to VLAN 2, we will designate one port as a trunk port for a connection to another VLAN-aware switch. This trunk port will carry tagged frames from all VLANs, allowing VLAN frames to maintain their VLAN ID across multiple switches.
Page 397: Walkthrough Stage Three, Port 10 Egress Setting
NOTE: Since Port 3 will connect to a single workstation, and is not to be used for switch-to-switch communications, the acceptable frame types allowed through this port will be all frame types (tagged and untagged). Since Port 3 will not receive VLAN frames from the work station, it is not necessary to filter frames.
Page 398 NOTE: Since Port 10 will be used for switch-to-switch communications, the PVID is left set on the default VLAN value of 1. This associates Port 10 with all VLANs on the switch. Since Port 10 will be used as a trunk port, only tagged frames will be allowed through the port.
Page 399: Examples
This effectively completes the configuration of a single VLAN, assigning it to a port, and configuring the switch to forward the frames received on that port to a trunk port. The trunk port in turn forward the frames as tagged to another switch.
Page 400: Example 1, Single Switch Operation
Figure 13-10 Example 1, Single Switch Operation 13.12.1 Solving the Problem To set up this switch, users will be assigned to two new VLANs, red stations to the Red VLAN, and blue stations to the Blue VLAN. The information below describes how the switch is configured to create these two VLANs and how users are assigned to them.
Page 401: Switch Configured For Vlans
Figure 13-11 Switch Configured for VLANs The switch will now classify each frame received as belonging to either the Red or Blue VLANs. Traffic from one VLAN will not be forwarded to the members of the other VLAN, and all frames transmitted by the switch will be normal, untagged Ethernet frames.
Page 402: Frame Handling
R1. 1. Station R1 transmits the broadcast frame. The switch receives this frame on Port 1. As the frame is received, the switch classifies it. The frame is untagged, so the switch classifies it as belonging to the VLAN that Port 1 is assigned to, the Red VLAN.

Example 2, VLANs Across Multiple Switches 13.13.1 Solving the Problem To solve the problem in this example, the users are assigned to VLANs using Switch 4 and Switch 2 as shown in Figure 13-12. Redco users are assigned to the Red VLAN and Blue Industries users to the Blue VLAN.
Page 405 By default the port remains as a member of the Default VLAN. With the original classification information inserted in the frame Tag Header, the receiving switch will maintain the original frame classification. GVRP is enabled on this port and will support dynamic VLANs created by GVRP.
Page 406 Ingress Filtering: ENABLED GVRP Status: DISABLED This causes the switch to classify all untagged frames received as belonging to the VLAN specified by each port PVID and to replace the previous PVID information in the port VLAN List with the new PVID information. This makes Port 1 part of the Blue VLAN, Port 3 part of the Red VLAN, and both are set to the VLAN frame format of untagged.
Page 407: Frame Handling
Switch 4 updates its Source Address Table in FDB ID 2 if it didn’t already have a dynamic entry for MAC address “Y” in FDB ID 2. Because Switch 4 received the frame on Port 1, it does not forward the frame out that port, but does forward the frame to Port 4.
Page 408: Transmitting To Switch 4
Figure 13-14 Transmitting to Switch 4 3. When Switch 2 receives the tagged frame on its Port 2, it checks the frame’s VLAN Tag Header and determines that the frame is classified as belonging to the Red VLAN, and that the frame is a broadcast frame.

MAC address, VLAN, and receive port. 5. The frame from the File Server is received on Switch 2, and forwarded to Switch 1 as a tagged frame classified as belonging to the Red VLAN. Switch 1 removes the tag and forwards the frame to Bridge 1, which in turn forwards the frame out of the port attached to User A.
Page 410: Example 5, Filtering Traffic According To A Classification
Layer 4 classification rule that will classify each RIP broadcast frame received on Port 25 of each switch to the Null VLAN. Since the Null VLAN is not associated with any ports, the frame will be dropped and not transmitted out any port.
Page 411: Example 4, Securing Sensitive Information According To Subnet
2. The VLAN Classification Configuration screen is used to configure the switch to detect and classify the incoming RIP broadcast frames on Port 25 to the Null VLAN. Since the Null VLAN is not assigned to any port, the frame is dropped (not transmitted out any port). The VLAN Classification Configuration screen is set as follows: •...

Page 414: Example 6, Locking A Mac Address To A Port Using Classification Rules
The following example illustrates how to add security by “locking” an individual MAC address to a port on the switch module (S1). This would typically be done to ensure that only a particular device can gain access to the network from a specific port. Traffic received by the switch from any MAC address other than the one assigned to the “locked”...

Page 417: A.1 Operation
The purpose of GVRP is to dynamically create VLANs across a switched network. When a VLAN is declared, the information is transmitted out GVRP configured ports on the switch in a GARP formatted frame using the GVRP multicast MAC address. A switch that receives this frame, examines the frame, and extracts the VLAN IDs.
Page 418: A-1 Example Of Vlan Propagation Via Gvrp
A-1, Switch 4, port 1 is registered as being a member of VLAN Blue and then declares this fact out all its ports (2 and 3) to Switch 1 and Switch 2. These two switches register this in the Port VLAN Lists of the ports (Switch 1, port 1 and Switch 2, port 1) that received the frames with the information.
Page 419: B.1 Igmp Overview
Internet Group Management Protocol (IGMP) is a multicast protocol used by routers. This protocol is supported by Enterasys Networks SmartSwitches when operating in the 802.1Q mode to “snoop” the IGMP frames. The multicast information is gleaned from the IGMP frame and a filter is created to send the stream of data only to those end stations that will receive it.
Page 420: Supported Features And Functions
Ports that receive queries are marked as upstream ports. It is assumed a router exists somewhere off this port, and responses are sent here. If the switch detects a router protocol on a port, that port is also marked as a router port. This keeps the switch from blocking traffic to other routers.
Page 421: Detecting Multicast Routers
The router(s) sends multicast routing protocol frames that get flooded throughout the network. By snooping on these protocol, the switch will mark ports as connected to a router. The port is put in a “forward all” mode where all multicast frames will be flooded. This allows all types of IP multicast traffic (including IGMP streams) to go to the router.
