Page 262: Special Commands
Special Commands With the above configuration, an AppleTalk frame received on any port will be classified into VLAN 2 (the AppleTalk VLAN), and the Port VLAN List of that port is updated to include VLAN 2. For instance, if Port 1 or 2 is connected to a new AppleTalk user, the AppleTalk frames received on that port are dynamically associated with VLAN 2 and VLAN 2 is added to the Port VLAN List of that port.
Page 263: Vlan Operation And Network Applications
VLAN Operation and Network Applications NOTE: It is recommended to read this chapter to gain an understanding of VLANs before configuring the switch. This chapter provides the following information: • Definition of VLANs (Section • Types of VLANs (Section •...
Page 264: Example Of A Vlan
Defining VLANs The creation of VLANs allows users located in separate areas or connected to separate ports to belong to a single VLAN group. Users that are assigned to such a group will send and receive broadcast and multicast traffic as though they were all connected to a common network. VLAN-aware switches isolate broadcast, multicast, and unknown traffic received from VLAN groups, so that traffic from stations in a VLAN are confined to that VLAN.
Page 265: Types Of Vlans
An 802.1Q VLAN switch determines the VLAN membership of a data frame by its Tag Header, described later in this chapter. If the frame received is not tagged, the switch classifies the frame into the VLAN that is assigned as the default VLAN of the switch.
Page 266: Other Vlan Strategies
FID cannot communicate with the members of another FID. 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 267 VLAN tag. 1D Trunk A connection from a switch that passes only untagged traffic. By default, a port designated as a 1D Trunk port has all VLANs on its Port VLAN List and is configured to transmit all frames as untagged frames.
Page 268: 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. 12.5.2 VLAN Components Before describing the operation of an 802.1Q VLAN, it is important to understand the basic...
Page 269: Configuration Process
12.6.3 Customizing the VLAN Forwarding List Each port on a VLAN-aware switch has a VLAN forwarding list that contains, as a minimum, the PVID of the VLAN configured. Additionally, the Port VLAN Forwarding List of each port can be configured to allow any number of VLANs to be added to its list.
Page 270: 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 271: 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 272: Known Unicasts
(SNMP or Telnet sessions) from a management station connected to a switch port that is a member of the same VLAN as the switch’s Host Data Port. (By default, this is the default VLAN.) When the switch is configured with VLANs, special precautions must be taken to use remote management.
Page 273: Switch Without Vlans
When the switch is powered up, the switch uses its default settings to switch frames like an 802.1D 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 12-3.
Page 274: Switch Management With Vlans
VLAN Configuration Figure 12-4 shows an example of a switch configured with port 1 on the Management VLAN port and the other users belonging to VLANs A, B, and C. Figure 12-4 Switch Management with VLANs To set up the switch shown in process described below: 1.
Page 275 Management VLAN for switch management. If the switch was connected to another switch via port 7, which was set as a 1Q Trunk port, then the management station connected to the Management VLAN port of either switch could manage both switches.
Page 276: Summary Of Vlan Local Management
A switch supporting 802.1Q VLANs provides the VLAN Configuration screens as a standard part of its Local Management hierarchy when the switch is configured to operate in 802.1Q Mode. The hierarchy of the Local Management screens pertaining to 802.1Q VLAN configuration is shown in Figure 12-5.

Page 279: Walkthrough Stage Two,Port Assignment Configuration Screen
Now that port 3 belongs to the TEST VLAN, we will designate one port as a 1Q Trunk port for a connection to another VLAN-aware switch. This 1Q Trunk port will carry traffic from all VLANs, allowing VLAN frames to maintain their VLAN ID across multiple switches.
Page 280: Walkthrough Stage Three, Test Vlan Assigned To Port 3
Quick VLAN Walkthrough 14.Use the arrow keys to highlight the SAVE command at the bottom of the screen. Press ENTER. Port 10 is now acting as a 1Q Trunk port and every VLAN is in its Port VLAN List. The frame format for every VLAN is also set to tagged.
Page 281: Walkthrough Stage Four, Activating Test Vlan
18.Use the arrow keys to highlight the SAVE command at the bottom of the screen. 19.Press ENTER. The message “SAVED OK” displays. The switch activates the new VLAN and the Admin Status field for VLAN ID 2 changes from Disabled to Enabled as shown in Figure 12-10.
Page 282 Quick VLAN Walkthrough 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 be forwarded with the VLAN information included in the frame.
Page 283: Examples
12.12 EXAMPLE 1, SINGLE SWITCH OPERATION This first example looks at the configuration of a single Ethernet switch for VLAN operation. In this example, two groups of three users are to be assigned to two VLANs to isolate them from one another.
Page 284: Solving The Problem
1. First, the switch is set for 802.1Q operation. Since traffic isolation is to be based on VLAN membership alone, the switch is set so the Red VLAN is a member of FID 2 and the Blue VLAN is a member of FID 3 from the Device VLAN Configuration screen.
Page 285: 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.
Page 286: Example 2, Vlans Across Multiple Switches
Example 2, VLANs Across Multiple Switches frame. The switch finds the MAC address and VLAN in this table, and recognizes that the MAC address and VLAN match for R1 is located out Port 1. 6. The switch examines its VLAN configuration information and determines that the frame for Red VLAN is allowed to be forwarded out Port 1 and that it must be sent in an untagged format.

Page 288: Solving The Problem
Example 2, VLANs Across Multiple Switches 12.13.1 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 12-14. Redco users are assigned to the Red VLAN and Blue Industries users to the Blue VLAN.
Page 289 Port 3, VLAN ID: 2 for the Red VLAN These settings change the configuration of the switch, so that Port 1 is part of Blue VLAN, Port 3 is part of Red VLAN, and both are set as frame type of untagged.
Page 290: Frame Handling
Port 4. Switch 4 updates its Source Address Table in FID 2 if it didn’t already have a dynamic entry for MAC address “Y” in FID 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 291: Transmitting To Switch 4
Example 2, VLANs Across Multiple Switches The VLAN Tag Header is inserted because Switch 4, Port 4 is designated as an 802.1Q Trunk port. In this case, the Port Mode setting for Port 4 is 802.1Q Trunk and the VLAN Frame format for that VLAN is tagged.
Page 292: Transmitting To Bridge 4
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.

User B as being located out Port 1. On Switch 4, the only port eligible to receive Red VLAN frames is Port 4, the 1Q Trunk. The frame is forwarded out Port 4 with the Red VLAN Tag header being added, as shown in Figure 12-19.
Page 297: Switch 2 Forwards To 1Q Trunk
3. Switch 2 receives the tagged Red VLAN frame on Port 2, as shown in Tag in the frame is maintained, classifying the frame as belonging to the Red VLAN. The switch forwards the broadcast frame out all the eligible ports, Ports 3 and 4. Switch 2 simultaneously updates its Source Address Table for FID 1 to reflect the location of User B (Port 2).

5. The Mail Server receives the broadcast frame and recognizes it. The Mail Server responds with a unicast frame to User B. This frame crosses the 1D Trunk and is received by Switch 1. In this example, Switch 1 classifies the unicast frame as belonging to the Default VLAN (the only membership for the 1D Trunk port in this example).

VLANs. The frame is tagged and transmitted out port 2. 7. Switch 4 receives the frame on its 1Q Trunk port, Port 4, and examines the frame’s Tag. The frame maintains its Default VLAN classification. The switch also refers to its Source Address Table, FID 1, to see if it can locate an entry for User B.

Switch 4. Ports 2, 3, 4, 5, 6, 7, and 8 of Switch 5 are connected to the Publication Department devices. These ports will be configured to classify all AppleTalk frames into the AppleTalk VLAN (Gray). The same ports will also be configured to classify all other protocol frames into a second VLAN (Yellow).
Page 302 3. To allow all frames (except the AppleTalk frames, which will be prevented in steps 4 and 5) from being transmitted out Port 1 to Switch 3 and the network backbone, Port VLAN IDs are assigned to all switch ports using the Port Assignment screen, as follows: •...
Page 303 Ports 2 through 8, the frame would be part of the Yellow VLAN and transmitted out Port 1 as a tagged frame to Switch 3. The frame would be handled in the same manner as described in the previous examples to route the frame to the Mail Server on the first floor.
Page 304: Example 5, Filtering Traffic According To A Layer 4 Classification Rule
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.

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: •...

SmartSwitch device. 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” port will be discarded.

Example 8, Locking a MAC Address to a Port Using Classification Rules 12.19.1 Solving the Problem Switch S1 needs to be configured with two 802.1Q VLANs. Since the switch, by default, already has one VLAN created (the Default VLAN), only one new VLAN will need to be created. In this example, the new VLAN will be named the Red VLAN.

Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP). GARP SWITCH OPERATION Some or all ports on the switch may be activated to operate under the GARP applications, GVRP and/or GMRP. A description of how GVRP and GMRP handle frames under GARP is described in Section A.1.1...
Page 314: Garp Switch Operation
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 315: Garp Multicast Registration Protocol (Gmrp
GARP Switch Operation A.1.2 GARP Multicast Registration Protocol (GMRP) GMRP functions in a similar fashion as GVRP, except that GMRP registers multicast addresses on ports. The GMRP uses the multicast address (01-80-C2-00-00-20) for controlling the flooding of multicast frames. End stations register with the port that they are connected to and tell the port which multicast frames they wish to receive.

Page 318: Supported Features And Functions
IGMP will run with GMRP, however, the IGMP does have higher priority then GMRP. • The switch does not act as the querier. A router is required for IGMP on the switch to function. • The switch will “snoop” on all incoming multicast addresses to detect query responses, as well as queries.
Page 319: Detecting Multicast Routers
The router(s) send multicast routing protocol frames which get flooded throughout the network. By snooping on the protocols, 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.
