dot1x critical recovery-action
Use
dot1x critical recovery-action
to configure the action that a port takes when an active
(reachable) RADIUS authentication server is detected for users in the 802.1X critical VLAN.
Use
undo dot1x critical recovery-action
to restore the default.
Syntax
dot1x critical recovery-action reinitialize
undo dot1x critical recovery-action
Default
When a reachable RADIUS server is detected, the system removes the port or 802.1X users from
the critical VLAN without triggering authentication.

Parameters
reinitialize
: Enables the port to trigger 802.1X re-authentication on detection of a reachable RADIUS
authentication server for users in the critical VLAN.
Usage guidelines
The
dot1x critical recovery-action
command takes effect only for the 802.1X users in the critical
VLAN on a port. It enables the port to take one of the following actions to trigger 802.1X
authentication after removing 802.1X users from the critical VLAN on detection of a reachable
RADIUS authentication server:
•
If MAC-based access control is used, the port sends a unicast Identity EAP/Request to each
802.1X user.
•
If port-based access control is used, the port sends a multicast Identity EAP/Request to all the
802.1X users attached to the port.
Examples
# Configure port GigabitEthernet 3/0/1 to trigger 802.1X re-authentication on detection of an active
RADIUS authentication server for users in the critical VLAN.

dot1x domain-delimiter
Use
dot1x domain-delimiter
to specify a set of domain name delimiters supported by the access
device. Any character in the configured set can be used as the domain name delimiter for 802.1X
