802.1x Commands
517
Syntax
• dot1x port-control { auto | force-authorized | force-unauthorized }
• no dot1x port-control
• auto — Enables 802.1X authentication on the interface and causes the port to transition to the
authorized or unauthorized state based on the 802.1X authentication exchange between the port
and the client.
• force-authorized — Disables 802.1X authentication on the interface and causes the port to
transition to the authorized state without any authentication exchange required. The port resends
and receives normal traffic without 802.1X-based authentication of the client.
• force-unauthorized — Denies all access through this interface by forcing the port to transition to
the unauthorized state and ignoring all attempts by the client to authenticate. The device cannot
provide authentication services to the client through the interface.
Default Configuration
Port is in the force-authorized state.
Command Mode
Interface Configuration (Ethernet) mode.
User Guidelines
• It is recommended to disable Spanning Tree or to enable spanning-tree PortFast mode on 802.1x edge
ports (ports in
auto state that are connected to end stations), in order to get immediately to the
forwarding state after successful authentication.
Examples
The following example enables 802.1X authentication on Ethernet port 1/e16.
dot1x re-authentication
The dot1x re-authentication Interface Configuration mode command enables periodic
re-authentication of the client. Use the no form of this command to return to the default configuration.

• no dot1x re-authentication
