Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
To return to the default value, use the no dot1x auth-fail max-attempts interface configuration
command.
This example shows how to set 2 as the number of authentication attempts allowed before the port moves
to the restricted VLAN:
Switch(config-if)# dot1x auth-fail max-attempts 2
Configuring the Inaccessible Authentication Bypass Feature
You can configure the inaccessible bypass feature, also referred to as critical authentication or the AAA
fail policy.
Note You must configure the RADIUS server parameters on the switch to monitor the RADIUS server state
(see the
“Configuring the Switch-to-RADIUS-Server Communication” section on page 10-40 ). You
must also configure the idle time, dead time, and dead criteria.
If you do not configure these parameters, the switch prematurely changes the RADIUS server status to
dead.
Beginning in privileged EXEC mode, follow these steps to configure the port as a critical port and enable
the inaccessible authentication bypass feature. This procedure is optional.
Step 6 dot1x auth-fail max-attempts max
attempts Specify a number of authentication attempts to allow before a port moves
to the restricted VLAN. The range is 1 to 3, and the default is 3.
Step 7 end Return to privileged EXEC mode.
Step 8 show authentication interface-id
or
show dot1x interface interface-id
(Optional) Verify your entries.
Step 9 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 radius-server dead-criteria time time
tries tries (Optional) Set the conditions that are used to decide when a RADIUS
server is considered unavailable or dead.
The range for time is from 1 to 120 seconds. The switch dynamically
determines the default seconds value that is 10 to 60 seconds.
The range for tries is from 1 to 100. The switch dynamically determines
the default tries parameter that is 10 to 100.
Step 3 radius-server deadtime minutes (Optional) Set the number of minutes that a RADIUS server is not sent
requests. The range is from 0 to 1440 minutes (24 hours). The default is
0 minutes.
