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
).
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.
