Usage Information Related Commands 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 amount 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. dot1x mac-auth-bypass Enable MAC authentication bypass. If 802.1X times out because the host did not respond to the Identity Request frame, FTOS attempts to authenticate the host based on its MAC address.
