Chapter 2 Catalyst 3560 Switch Cisco IOS Commands dot1x auth-fail vlan When a restricted VLAN port is moved to an unauthorized state, the authentication process restarts. If the supplicant fails the authentication process again, the authenticator waits in the held state. After the supplicant has correctly re-authenticated, all IEEE 802.1x ports are reinitialized and treated as normal IEEE 802.1x ports. When you reconfigure a restricted VLAN as a different VLAN, any ports in the restricted VLAN are also moved, and the ports stay in their currently authorized state. When you shut down or remove a restricted VLAN from the VLAN database, any ports in the restricted VLAN are immediately moved to an unauthorized state, and the authentication process restarts. The authenticator does not wait in a held state because the restricted VLAN configuration still exists. While the restricted VLAN is inactive, all authentication attempts are counted so that when the restricted VLAN becomes active, the port is immediately placed in the restricted VLAN. The restricted VLAN is supported only in single-host mode (the default port mode). For this reason, when a port is placed in a restricted VLAN, the supplicant's MAC address is added to the MAC address table, and any other MAC address that appears on the port is treated as a security violation. Examples This example shows how to configure a restricted VLAN on port 1: Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# interface gigabitethernet0/1 Switch(config-if)# dot1x auth-fail vlan 40 Switch(config-if)# end Switch(config)# end Switch# You can verify your configuration by entering the show dot1x [interface interface-id] privileged EXEC command. Related Commands Command dot1x auth-fail max-attempts [max-attempts] show dot1x [interface interface-id] Description Configures the number of authentication attempts allowed before assigning a supplicant to the restricted VLAN. Displays IEEE 802.1x status for the specified port. 78-16405-05 Catalyst 3560 Switch Command Reference 2-85
