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 reauthenticationinterval (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: You can create the Layer 3 portion of a guest VLAN and authentication fail VLANs 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 — Configure an authentication failure VLAN.• dot1x reauthentication — Enable periodic re-authentication of the client.• dot1x reauth-max —Configure the maximum number of times to re-authenticate a port before it becomes unauthorizeddot1x host-modeEnable single-host or multi-host authentication.Syntax dot1x host-mode {single-host | multi-host | multi-auth}Parameters single-host Enable single-host authentication.multi-host Enable multi-host authentication.multi-auth Enable multi-supplicant authentication.Defaults single-hostCommand Modes INTERFACECommand History This guide is platform-specific.
