Configuring Periodic Re-Authentication - Cisco 3032 Software Configuration Manual

Chapter 9 Configuring IEEE 802.1x Port-Based Authentication
Command
Step 5
show authentication interface
interface-id
or
show dot1x interface interface-id
Step 6 copy running-config startup-config
To disable multiple hosts on the port, use the no authentication host-mode or the
no dot1x host-mode multi-host interface configuration command.
This example shows how to enable 802.1x authentication and to allow multiple hosts:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x host-mode multi-host
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 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.
