4.2.39 Configuring IAB
Authentication with
Recovery action.
When RADIUS server is failed, some users won't be able to pass the authentication, and the
switch will authorize the users to access network. When RADIUS server is recovered, this
feature will allow IAB users under the port to reinitialize authentication to verify user's identity.
Execute the following steps to configure IAB authentication with recovery action:
Command Function
DES-7200# configure terminal
Enter global configuration mode.
DES-7200(config)# interface <interface-id>
Enter interface configuration mode.
DES-7200(config-if)# dot1x critical recovery
action reinitialize
Allow IAB users under the port to reinitialize
authentication when the server has recovered.
DES-7200(config-if)# end
Return to privilege mode.
DES-7200# show running-config
Display all configurations.
The following example shows how to configure Inaccessible Authentication Bypass:
DES-7200# configure terminal
DES-7200(config)# interface fa 0/1
DES-7200(config-if)# dot1x port-control auto
DES-7200(config-if)# dot1x critical
DES-7200(config-if)# dot1x critical recovery action reinitialize
Note
After the server has recovered, normally authenticated users under the
port can continue to access the network without re-authentication. After
the server is failed, users authorized to access network through IAB
authentication will be subject to the re-authentication initiated by the
switch.

802.1x
Our 802.1X provides a full range of state machine information, which is very useful for network
management and can be used by the administrator to monitor user status in real time and
make easy troubleshooting.
