Command History
Usage Guidelines 802.1x accounting requires the RADIUS server.
This command enables the AAA client’s accounting feature to forward 802.1x update and watchdog
packets from the 802.1x supplicant (workstation client) to the authentication (RADIUS) server.
(Watchdog packets are defined as EAPOL-LOGON, EAPOL-LOGOFF, and EAPOL-INTERIM
messages.) Successful authentication and authorization of the supplicant by the authentication server is
required before these packets are considered valid and are forwarded. When the client is reauthenticated,
an interim-update accounting notice is sent to the accounting server.
Examples The following example shows how to generate a logoff after a switch reboots:
Switch(config)# aaa accounting system default start-stop group radius
Note The RADIUS authentication server must be properly configured to accept and log update or watchdog
packets from the AAA client.
