174 Configuring and managing Mobility Domain roaming

Displaying roaming VLANs and their affinities

The command show roaming vlan displays all VLANs in the Mobility Domain, the WSSs servicing the VLANs, and
their 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 that
VLAN. A higher value represents preferred connection to the VLAN. (For more information, see
affinity" (page 108).)
To display roaming VLANs, type the following command:
WSS# show roaming vlan
VLAN
---------------- --------------- --------
vlan-eng
vlan-fin
vlan-pm
vlan-wep
vlan-wep
(For more information about this command and the fields in the output, see the
Series Command Line Reference.)

Displaying tunnel information

The command show tunnel displays the tunnels that the WSS is hosting to distribute to a locally attached VLAN. To
display tunnel information, type the following command:
WSS# show tunnel
VLAN Local Address
vlan-eng 192.168.12.7
vlan-eng 192.168.12.7
vlan-pm 192.168.12.7
(For more information about this command and the fields in the output, see the
Series Command Line Reference.)

Understanding the sessions of roaming users

When a wireless client successfully roams from one AP to another, its sessions are affected in the following ways:
• The WSS treats this client session as a roaming session and not a new session.
• RADIUS accounting is handled as a continuation of an existing session, rather than a new one.
• The session with the roamed-from AP is cleared from the WSS, even if the client does not explicitly disassociate
from the AP and the IEEE 802.1X reauthentication period has not expired.
