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: You can create the Layer 3 portion of a guest VLAN and authentication
fail VLANs 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.
