174 Configuring and managing Mobility Domain roamingNN47250-500 (320657-F Version 02.01)Displaying roaming VLANs and their affinitiesThe command show roaming vlan displays all VLANs in the Mobility Domain, the WSSs servicing the VLANs, andtheir tunnel affinity values configured on each switch for the VLANs.The member WSS that offers the requested VLAN reports the affinity number. If multiple WSSs have native attach-ments to the VLAN, the affinity values they advertise are a way to attract tunneled traffic to a particular WSS for thatVLAN. A higher value represents preferred connection to the VLAN. (For more information, see “Changing tunnelingaffinity” (page 108).)To display roaming VLANs, type the following command:WSS# show roaming vlanVLAN WSS Affinity---------------- --------------- --------vlan-eng 192.168.12.7 5vlan-fin 192.168.15.5 5vlan-pm 192.168.15.5 5vlan-wep 192.168.12.7 5vlan-wep 192.168.15.5 5(For more information about this command and the fields in the output, see the Nortel WLAN Security Switch 2300Series Command Line Reference.)Displaying tunnel informationThe command show tunnel displays the tunnels that the WSS is hosting to distribute to a locally attached VLAN.
