You can configure the Catalyst 4500 series switch to use a RADIUS-provided reauthentication timeout.

To configure RADIUS-provided timeouts, perform this task:

This example shows how to configure the switch to derive the re-authentication period from the server:

Switch# configure terminal

Switch(config)# interface fa3/1

Switch(config-if)# dot1x timeout reauth-period server

Switch(config-if)# end

Switch)# show dot1x interface fa2/1

If you plan to implement system-wide accounting, you should also configure 802.1X accounting. 
Moreover, you need to inform the accounting server of the system reload event when the system is 
reloaded. Doing this, ensures that the accounting server knows that all outstanding 802.1X sessions on 
this system are closed.

After you configure 802.1X authentication and switch-to-RADIUS server communication, perform this 
task to enable 802.1X accounting:

Switch# configure terminal

Enters global configuration mode.

Switch(config)# interface

 

interface-id

Enters interface configuration mode.

Switch(config-if)# dot1x-timeout 

{

interface

}

Sets the re-authentication period (seconds).

Switch(config-if)# end

Returns to privileged EXEC mode.

Switch # show dot1x 

interface

Verifies your entries.

Switch # copy running-config 

(Optional) Saves your entries in the configuration file.

Switch# configure terminal

Enters global configuration mode.

Switch(config)# aaa accounting 

Enables 802.1X accounting, using the list of all RADIUS servers.
