Usage
Information
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).
