Usage Information 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 reauthentication interval (dot1x
reauthentication).
If the host fails authentication for the designated number of times, the authenticator
places the port in authentication failed VLAN (dot1x auth-fail-vlan).
Use this command in Configuration Terminal Batch mode to configure a guest VLAN in
a dual-homing setup.

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.
