dot1x critical (global configuration)
Use the dot1x critical global configuration command on a standalone switch to configure the parameters
for the inaccessible authentication bypass feature, also referred to as critical authentication or the
authentication, authorization, and accounting (AAA) fail policy. To return to default settings, use the no
form of this command.
Syntax Description
eapol
recovery delay milliseconds
Defaults
The switch does not send an EAPOL-Success message to the host when the switch successfully
authenticates the critical port by putting the critical port in the critical-authentication state.
The recovery delay period is 1000 milliseconds (1 second).

Usage Guidelines
Use the eapol keyword to specify that the switch sends an EAPOL-Success message when the switch
puts the critical port in the critical-authentication state.
Use the recovery delay milliseconds keyword to 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
default recovery delay period is 1000 milliseconds. A port can be re-initialized every second.
To enable inaccessible authentication bypass on a port, use the dot1x critical interface configuration
command. To configure the access VLAN to which the switch assigns a critical port, use the dot1x
critical vlan vlan-id interface configuration command.
Examples
This example shows how to set 200 as the recovery delay period on the switch:
Switch# dot1x critical recovery delay 200
You can verify your configuration by entering the show dot1x privileged EXEC command.
