14.3.8 Re-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).
14.3.9 Periodic 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
