Usage Information
802.1X authentication is enabled when an interface is connected to the switch. If the host fails to respond within a
designated amount of time, the authenticator places the port in the guest VLAN.
If a device does not respond within 30 seconds, it is assumed that the device is not 802.1X capable. Therefore, a
guest VLAN is allocated to the interface and authentication for the device occurs at the next re-authentication
interval (dot1x reauthentication).
If the host fails authentication for the designated number of times, the authenticator places the port in
authentication failed VLAN (dot1x auth-fail-vlan).

NOTE: The layer 3 portion of guest VLAN and authentication fail VLANs can be created regardless if
the VLAN is assigned to an interface or not. After an interface is assigned a guest VLAN (which has an
IP address), routing through the guest VLAN is the same as any other traffic. However, the interface
may join/leave a VLAN dynamically.
dot1x auth-fail-vlan — configures a VLAN for authentication failures.
dot1x reauthentication — enables periodic re-authentication.
show dot1x interface — displays the 802.1X information on an interface.
