Example of Conguring and Verifying Port Authentication
The following example shows conguration information for a port for which the authenticator re-transmits an EAP Request Identity frame:
• after 90 seconds and a maximum of 10 times for an unresponsive supplicant
• re-transmits an EAP Request Identity frame
The bold lines show the new re-transmit interval, new quiet period, and new maximum re-transmissions.

Forcibly Authorizing or Unauthorizing a Port
The 802.1X ports can be placed into any of the three states:
• ForceAuthorized — an authorized state. A device connected to this port in this state is never subjected to the authentication process,
but is allowed to communicate on the network. Placing the port in this state is same as disabling 802.1X on the port.
• ForceUnauthorized — an unauthorized state. A device connected to a port in this state is never subjected to the authentication
process and is not allowed to communicate on the network. Placing the port in this state is the same as shutting down the port. Any
attempt by the supplicant to initiate authentication is ignored.
• Auto — an unauthorized state by default. A device connected to this port in this state is subjected to the authentication process. If the
process is successful, the port is authorized and the connected device can communicate on the network. All ports are placed in the
Auto state by default.
To set the port state, use the following command.
• Place a port in the ForceAuthorized, ForceUnauthorized, or Auto state.
INTERFACE mode
dot1x port-control {force-authorized | force-unauthorized | auto}
The default state is auto.
Example of Placing a Port in Force-Authorized State and Viewing the Conguration
The example shows conguration information for a port that has been force-authorized.
The bold line shows the new port-control state.
