Manually Re-Authenticating A Client Connected To A Port; Changing The Quiet Period - Cisco Catalyst 2950 Software Configuration Manual

Configuring IEEE 802.1x Authentication
Command

Step 7 copy running-config startup-config
To disable periodic re-authentication, use the no dot1x reauthentication interface configuration
command. To return to the default number of seconds between re-authentication attempts, use the no
dot1x timeout reauth-period global configuration command.
This example shows how to enable periodic re-authentication and set the number of seconds between
re-authentication attempts to 4000:
Switch(config-if)# dot1x reauthentication
Switch(config-if)# dot1x timeout reauth-period 4000

Manually Re-Authenticating a Client Connected to a Port

You can manually re-authenticate the client connected to a specific port at any time by entering the dot1x
re-authenticate interface interface-id privileged EXEC command. This step is optional. If you want to
enable or disable periodic re-authentication, see the
page
This example shows how to manually re-authenticate the client connected to a port:
Switch# dot1x re-authenticate interface fastethernet0/1

Changing the Quiet Period

When the switch cannot authenticate the client, the switch remains idle for a set period of time, and then
tries again. The idle time is determined by the quiet-period value. A failed authentication of the client
might occur because the client provided an invalid password. You can provide a faster response time to
the user by entering a smaller number than the default.
Beginning in privileged EXEC mode, follow these steps to change the quiet period. This procedure is
optional.
