Chapter 9 Configuring IEEE 802.1x Port-Based Authentication
Displaying IEEE 802.1x Statistics and Status
Beginning in privileged EXEC mode, follow these steps to configure IEEE 802.1x accounting after AAA
is enabled on your switch. This procedure is optional.
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 IEEE 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
Displaying IEEE 802.1x Statistics and Status
To display IEEE 802.1x statistics for all interfaces, use the show dot1x all statistics privileged EXEC
command. To display IEEE 802.1x statistics for a specific interface, use the show dot1x statistics
interface interface-id privileged EXEC command.
To display the IEEE 802.1x administrative and operational status for the switch, use the show dot1x all
privileged EXEC command. To display the IEEE 802.1x administrative and operational status for a
specific interface, use the show dot1x interface interface-id privileged EXEC command.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the port to be configured, and enter interface configuration mode.
Step 3
aaa accounting dot1x default
start-stop group radius
Enable IEEE 802.1x accounting using the list of all RADIUS servers.
Step 4
aaa accounting system default
start-stop group radius
(Optional) Enables system accounting (using the list of all RADIUS
servers) and generates system accounting reload event messages when the
switch reloads.
Step 5
end Return to privileged EXEc mode.
Step 6
show running-config Verify your entries.
Step 7
copy running-config startup-config (Optional) Saves your entries in the configuration file.
