3Com WX2200 3CRWX220095A manual Creating a Vlan, To create a VLAN, use the following command

Configuring and Managing VLANs 91

If the WX switch that is not in the user’s VLAN has a choice of more than one other WX switch through which to tunnel the user’s traffic, the switch selects the other switch based on an affinity value. This is a numeric value that each WX switch within a Mobility Domain advertises, for each of its VLANs, to all other switches in the Mobility Domain. A switch outside the user’s VLAN selects the other operational switch that has the highest affinity value for the user’s VLAN to forward traffic for the user.

If more than one WX switch has the highest affinity value, MSS randomly selects one of the switches for the tunnel.

Configuring a VLAN You can configure the following VLAN parameters:

„VLAN number

„VLAN name

„Port list (the ports in the VLAN)

„Per-port tag value (an 802.1Q value representing a virtual port in the VLAN)

„Tunnel affinity (a value that influences tunneling connections for roaming)

„MAC restriction list (if you want to prevent clients from communicating with one another directly at Layer 2)

Creating a VLAN

To create a VLAN, use the following command:

set vlan vlan-numname name

Specify a VLAN number from 2 to 4093, and specify a name up to 16 alphabetic characters long.

You cannot use a number as the first character in a VLAN name. 3Com recommends that you do not use the same name with different capitalizations for VLANs or ACLs. For example, do not configure two separate VLANs with the names red and RED.

3Com recommends that you do not use the name default. This name is already used for VLAN 1. 3Com also recommends that you do not rename the default VLAN.
