3com WX1200 3CRWX120695A Manuel D’Utilisation

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.

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)

To create a VLAN, use the following command:

set vlan vlan-num name 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.
