Configuring 802.1x Port-Based Authentication
Note
You must configure the RADIUS server to perform accounting tasks, such as logging start, stop, and
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.
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
aaa accounting dot1x default
start-stop group radius
Step 4
aaa accounting system default
start-stop group radius
Step 5
end
Step 6
show running-config
Step 7
copy running-config startup-config
Use the show radius statistics privileged EXEC command to display the number of RADIUS messages
that do not receive the accounting response message.
This example shows how to configure 802.1x accounting. The first command configures the RADIUS
server, specifying 1813 as the UDP port for accounting:
Switch(config)# radius-server host 172.120.39.46 auth-port 1812 acct-port 1813 key rad123
Switch(config)# aaa accounting dot1x default start-stop group radius
Switch(config)# aaa accounting system default start-stop group radius
