Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
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. This procedure is optional.
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 interface 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
“Configuring Periodic Re-Authentication” section
on page 10-26.
This example shows how to manually re-authenticate the client connected to a port:
Switch# dot1x re-authenticate interface gigabitethernet1/2
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the port to be configured, and enter interface configuration mode.
Step 3
dot1x reauthentication Enable periodic re-authentication of the client, which is disabled by
default.
Step 4
dot1x timeout reauth-period {seconds |
server}
Set the number of seconds between re-authentication attempts.
The keywords have these meanings:
• seconds—Sets the number of seconds from 1 to 65535; the default is
3600
seconds.
• server—Sets the number of seconds based on the value of the
Session-Timeout RADIUS attribute (Attribute[27]) and the
Termination-Action RADIUS attribute (Attribute [29]).
This command affects the behavior of the switch only if periodic
re-authentication is enabled.
Step 5
end Return to privileged EXEC mode.
Step 6
show dot1x interface interface-id Verify your entries.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
