Service Manual

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: 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 trac. However, the interface
may join/leave a VLAN dynamically.
