Command History
Usage Guidelines 802.1X accounting 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 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 This example shows how to configure 802.1X accounting:
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.
