Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring 802.1x Authentication
To configure the port as an 802.1x port access entity (PAE) authenticator, which enables 802.1x on the
port but does not allow clients connected to the port to be authorized, use the
dot1x pae authenticator
interface configuration command.
This example shows how to disable 802.1x authentication on the port:
Switch(config)#
interface gigabitethernet2/0/1
Switch(config-if)#
no dot1x pae authenticator

to the default values. This procedure is optional.
Step 3
no dot1x pae

Step 4
end
Return to privileged EXEC mode.
Step 5
