Enabling Periodic ReAuthentication

When a client is authenticated to a switch port using 802.1x, the port remains set with the supplicant attributes until a reboot occurs. To validate the user on an ongoing basis, periodic re-authentication may be enabled on a per-port basis. You can also specify the time period between authentications. Table 18-3 describes the command syntax for periodic re-authentication.

Sets the number of seconds between re-authentication attempts. The range from 1 to 65,535 with a default setting of 3600 seconds.
