14.3.8Re-authentication by the client service

The client service is able to enforce a re-authentication, given the configured interval (see 2.0.A), independent of the switch's configuration. After the configured amount of seconds elapsed the Client service will start the authentication sequence. By sending a EAPOL Start packet (see: 2.3.I) and waiting for the identity request starting the authentication sequence (see: 2.3.II).

14.3.9Periodic client re-authentication by the switch

You can enable periodic 802.1X client re-authentication and specify how often it occurs. If you do not specify a time period before enabling re-authentication, the number of seconds between re-authentication attempts is 3600 (1 hour). This option must be changed either through a command line interface on the switch or the web interface.

Beginning in privileged EXEC mode, follow these steps to enable periodic re-authentication of the client and to configure the number of seconds between re-authentication attempts.

Commands:

•configure terminal

Enter global configuration mode

•interface <interface-id>

Specify the port to be configured, and enter interface configuration mode

•dot1x re-authentication

Enable periodic re-authentication of the client, which is disabled by default.

•dot1x timeout reauth-period <seconds>

Set the number of seconds between re-authentication attempts.

The range is 1 to 65535; the default is 3600 seconds.

This command affects the behavior of the switch only if the periodic re-authentication is en- abled.

•end

Return to privileged EXEC mode.

•show dot1x interface
