Configuring 802.1X Accounting - Cisco IE-3000-8TC Software Configuration Manual

Chapter 12 Configuring IEEE 802.1x Port-Based Authentication
Command
Step 5
show authentication interface
interface-id
or
show dot1x interface interface-id
Step 6
copy running-config startup-config
To return to the default re-authentication number, use the no dot1x max-reauth-req interface
configuration command.
This example shows how to set 4 as the number of times that the switch restarts the authentication
process before the port changes to the unauthorized state:
Switch(config-if)# dot1x max-reauth-req 4

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.

Purpose
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify the port to be configured, and enter interface configuration mode.
Enable 802.1x accounting using the list of all RADIUS servers.
(Optional) Enables system accounting (using the list of all RADIUS
servers) and generates system accounting reload event messages when the
switch reloads.
Return to privileged EXEc mode.
