You can configure the inaccessible authentication bypass feature and the restricted VLAN on an

IEEE 802.1x port. If the switch tries to re-authenticate a critical port in a restricted VLAN and all the

RADIUS servers are unavailable, the switch changes the port state to the critical authentication state,

and it remains in the restricted VLAN.

You can configure the inaccessible bypass feature and port security on the same switch port.

This example shows how to enable the inaccessible authentication bypass feature on port 1:

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface gigabitethernet1/0/1

Switch(config-if)# dot1x critical

Switch(config-if)# end

Switch(config)# end

You can verify your configuration by entering the show dot1x [interface interface-id] privileged EXEC

manuals search engine

dot1x critical (interface configuration)

bypass feature on the switch.
