Chapter 8 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
To return to the RADIUS server default settings, use the no radius-server dead-criteria, the no
radius-server deadtime, and the no radius-server host global configuration commands. To return to
the default settings of inaccessible authentication bypass, use the no dot1x critical {eapol | recovery
delay} global configuration command. To disable inaccessible authentication bypass, use the no dot1x
critical interface configuration command.
This example shows how to configure the inaccessible authentication bypass feature:
Switch(config)# radius-server dead-criteria time 30 tries 20
Switch(config)# radius-server deadtime 60
Switch(config)# radius-server host 1.1.1.2 acct-port 1550 auth-port 1560 test username
user1 idle-time 30 key abc1234
Switch(config)# dot1x critical eapol
Switch(config)# dot1x critical recovery delay 2000
Switch(config)# interface gigabitethernet0/1
Switch(config)# radius-server deadtime 60
Switch(config-if)# dot1x critical
Switch(config-if)# dot1x critical recovery action reinitialize
Switch(config-if)# dot1x critical vlan 20
Switch(config-if)# end
Step 5
dot1x critical {eapol | recovery delay
milliseconds}
(Optional) Configure the parameters for inaccessible authentication
bypass:
eapol—Specify that the switch sends an EAPOL-Success message when
the switch successfully authenticates the critical port.
recovery delay milliseconds—Set the recovery delay period during
which the switch waits to re-initialize a critical port when a RADIUS
server that was unavailable becomes available. The range is from 1 to
10000 milliseconds. The default is 1000 milliseconds (a port can be
re-initialized every second).
Step 6
interface interface-id Specify the port to be configured, and enter interface configuration mode.
For the supported port types, see the “IEEE 802.1x Authentication
Configuration Guidelines” section on page 8-21.
Step 7
dot1x critical [recovery action
reinitialize | vlan vlan-id]
Enable the inaccessible authentication bypass feature, and use these
keywords to configure the feature:
• recovery action reinitialize—Enable the recovery feature, and
specify that the recovery action is to authenticate the port when an
authentication server is available.
• vlan vlan-id—Specify the access VLAN to which the switch can
assign a critical port. The range is from 1 to 4094.
Step 8
end Return to privileged EXEC mode.
Step 9
show dot1x [interface interface-id] (Optional) Verify your entries.
Step 10
copy running-config startup-config (Optional) Save your entries in the configuration file.
