Usage Guidelines 8 02.1X accountin g requires a RADIUS server.
This command enables the Authentication, Authorization, and Accounting (AAA) client’s accounting
feature to forward 802 .1X update and watchdog packets fr om the 80 2.1X suppli cant (worksta tion clie nt)
to the authentication (RADIUS) server. (Watchdog packets are defined as EAPOL-LOGON,
EAPOL-LOGOFF, and EAPOL-INTERIM messages.) Successful authentication and authoriza tion of
the supplicant by the authentication server is required before these packets are c onsidered valid and are
forwarded. When the client is reauthenticated, an interim-update accounting notice is sent to the
accounting server.
Examples This exampl e shows how to configure 802.1X a ccounting:
Switch(config)# aaa accounting dot1x 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.
