Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
This example shows how to enable MDA and to allow both a host and a voice device on the port:
Switch(config)# interface gigabitethernet3/0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x host-mode multi-domain
Switch(config-if)# switchport voice vlan 101
Switch(config-if)# end
Configuring Periodic Re-Authentication
You can enable periodic IEEE 802.1x client re-authentication and specify how often it occurs. If you do
not specify a time period before enabling re-authentication, the number of seconds between attempts is
3600.
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.
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 authentication periodic
or
dot1x reauthentication
Enable periodic re-authentication of the client, which is disabled by
default.
Step 4 authentication timer {{[inactivity |
reauthenticate] [server | am]} {restart
value}}
or
dot1x timeout reauth-period {seconds |
server}
Set the number of seconds between re-authentication attempts.
The authentication timer keywords have these meanings:
• inactivity—Interval in seconds after which if there is no activity from
the client then it is unauthorized
• reauthenticate—Time in seconds after which an automatic
re-authentication attempt is be initiated
• server am—Interval in seconds after which an attempt is made to
authenticate an unauthorized port
• restart value—Interval in seconds after which an attempt is made to
authenticate an unauthorized port
The dot1x timeout reauth-period 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.
