Configuring 802.1x Accounting
Enabling AAA system accounting with 802.1x accounting allows system reload events to be sent to the
accounting RADIUS server for logging. The server can then infer that all active 802.1x sessions are
closed.
Because RADIUS uses the unreliable UDP transport protocol, accounting messages might be lost due to
poor network conditions. If the switch does not receive the accounting response message from the
RADIUS server after a configurable number of retransmissions of an accounting request, this system
message appears:
Accounting message %s for session %s failed to receive Accounting Response.
When the stop message is not sent successfully, this message appears:
00:09:55: %RADIUS-4-RADIUS_DEAD: RADIUS server 172.20.246.201:1645,1646 is not responding.
You must configure the RADIUS server to perform accounting tasks, such as logging start, stop, and
Note
interim-update messages and time stamps. To turn on these functions, enable logging of
"Update/Watchdog packets from this AAA client" in your RADIUS server Network Configuration tab.
Next, enable "CVS RADIUS Accounting" in your RADIUS server System Configuration tab.
Beginning in privileged EXEC mode, follow these steps to configure 802.1x accounting after AAA is
enabled on your switch. This procedure is optional.
