Resetting The Ieee 802.1X Configuration To The Default Values; Configuring Ieee 802.1X Accounting - Cisco ME 3400 Software Configuration Manual

Chapter 8 Configuring IEEE 802.1x Port-Based Authentication
Enter the dot1x host-mode single-host interface configuration command to set the interface to allow a
single host on the port.
Although visible in the command-line interface help, the dot1x host-mode multi-domain interface
Note
configuration command is not supported. Configuring this command on an interface causes the interface
to go into the error-disabled state.
To disable multiple hosts on the port, use the no dot1x host-mode multi-host interface configuration
command.
This example shows how to enable IEEE 802.1x and to allow multiple hosts:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x host-mode multi-host

Resetting the IEEE 802.1x Configuration to the Default Values

Beginning in privileged EXEC mode, follow these steps to reset the IEEE 802.1x configuration to the
default values. This procedure is optional.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 dot1x default
Step 4 end
Step 5
show dot1x interface interface-id
Step 6 copy running-config startup-config

Configuring IEEE 802.1x Accounting

Enabling AAA system accounting with IEEE 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 IEEE 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.

Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the port to be configured.
Reset the configurable IEEE 802.1x parameters to the default values.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
