Manually Reauthenticating A Client Connected To A Port; Changing The Quiet Period - Cisco 4500M Software Manual

Chapter 31 Understanding and Configuring 802.1X Port-Based Authentication
Command
Step 3
Switch(config-if)# dot1x
re-authentication
Step 4
Switch(config)# dot1x timeout
reauth-period seconds
Step 5
Switch(config)# end
Step 6
Switch# show dot1x all
Step 7
Switch(config)# copy running-config
startup-config
To disable periodic reauthentication, use the no dot1x re-authentication interface configuration
command. To return to the default number of seconds between reauthentication attempts, use the no
dot1x timeout reauth-period global configuration command.
This example shows how to enable periodic reauthentication and set the number of seconds between
reauthentication attempts to 4000:
Switch(config)# dot1x timeout reauth-period 4000
Switch(config)# dot1x re-authentication

Manually Reauthenticating a Client Connected to a Port

You can manually reauthenticate a client connected to a specific port at any time by entering the dot1x
re-authenticate interface interface-id privileged EXEC command. If you want to enable or disable
periodic reauthentication, see the
This example shows how to manually reauthenticate the client connected to Fast Ethernet port 1/1:
Switch# dot1x re-authenticate interface fastethernet1/1
Starting reauthentication on FastEthernet1/1

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 number smaller than the default.
To change the quiet period, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface
interface-id
OL-6696-01
Purpose
Enables periodic reauthentication of the client, which is disabled by
default.
Specifies the number of seconds between reauthentication attempts.
The range is 1 to 65,535; the default is 3600 seconds.
This command affects the behavior of the switch only if periodic
reauthentication is enabled.
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
"Enabling Periodic Reauthentication" section on page
Purpose
Enters global configuration mode.
Enters interface configuration mode and specifies the interface to be
enabled for timeout quiet-period.
