Viewing roaming accounting records
During roaming, accounting is treated as a continuation of an existing session, rather than a new session. The
following sample output shows a wireless user roaming from one WSS to another WSS.
From the accounting records, you can determine the user’s activities by viewing the Acct-Status-Type, which
varies from START to UPDATE to STOP, and the Called-Station-Id, which is the MAC address of the AP
through which the wireless user accessed the network. The Acct-Multi-Session-Id is guaranteed to be globally
unique for the client.
By entering show accounting statistics commands on each WSS involved in the roaming, you can determine
the user’s movements between WSSs when accounting is configured locally.
