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 re-authentication interval (dot1x reauthentication).
If the host fails authentication for the designated amount of times, the authenticator places the
port in authentication failed VLAN (dot1x auth-fail-vlan).
