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 switch to another WSS switch.
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 access point
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 switch involved in the roaming, you can determine the
user’s movements between WSS switches when accounting is configured locally.
