If the host fails to respond within adesignated 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, aguest VLAN is allocated to the interface and authentication for the device occurs at the next re-authenticationinterval (dot1x reauthentication).If the host fails authentication for the designated number of times, the authenticator places the port inauthentication failed VLAN (dot1x auth-fail-vlan).NOTE: The layer 3 portion of guest VLAN and authentication fail VLANs can be created regardless ifthe VLAN is assigned to an interface or not. After an interface is assigned a guest VLAN (which has anIP address), routing through the guest VLAN is the same as any other traffic. However, the interfacemay join/leave a VLAN dynamically.Related Commands • 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-bypassEnable MAC authentication bypass. If 802.1X times out because the host did not respond to the Identity Request frame, Dell NetworkingOS attempts to authenticate the host based on its MAC address.Syntax [no] dot1x mac-auth-bypassDefaults DisabledCommand Modes INTERFACECommand History This guide is platform-specific.
