Chapter 6 Configuring IEEE 802.1x Port-Based Authentication
Configuring IEEE 802.1x Authentication
Configuring the Host Mode
Beginning in privileged EXEC mode, follow these steps to allow multiple hosts (clients) on an
IEEE 802.1x-authorized port that has the dot1x port-control interface configuration command set to
auto. This procedure is optional.
To disable multiple hosts on the port, use the no dot1x host-mode multi-host interface configuration
command.
This example shows how to enable IEEE 802.1x authentication and to allow multiple hosts:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x host-mode multi-host
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 which multiple hosts are indirectly attached, and enter
interface configuration mode.
Step 3
dot1x host-mode multi-host Allow multiple hosts (clients) on an IEEE 802.1x-authorized port.
Make sure that the dot1x port-control interface configuration command
set is set to auto for the specified interface.
Step 4
end Return to privileged EXEC mode.
Step 5
show dot1x interface interface-id Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
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.
