Configuring Port-Based and User-Based Access Control (802.1X)
Configuring Switch Ports as 802.1X Authenticators
1. Enable 802.1X Authentication on Selected Ports
This task configures the individual ports you want to operate as 802.1X
authenticators for point-to-point links to 802.1X-aware clients or switches,
and consists of two steps:
A. Enable the selected ports as authenticators.
B. Specify either user-based or port-based 802.1X authentication.
(Actual 802.1X operation does not commence until you perform step 5 on page
13-26 to activate 802.1X authentication on the switch.)
Note If you enable 802.1X authentication on a port, the switch automatically dis-
ables LACP on that port. However, if the port is already operating in an LACP
trunk, you must remove the port from the trunk before you can configure it
for 802.1X authentication.
A. Enable the Selected Ports as Authenticators and Enable
the (Default) Port-Based Authentication
Syntax: [ no ] aaa port-access authenticator < port-list >
Enables specified ports to operate as 802.1X authenticators
and enables port-based authentication. (To enable user-
based authentication, execute this command first, and then
execute the client-limit < port-list > version of this command
described in the next section.) The no form of the command
removes 802.1X authentication from < port-list >. To activate
configured 802.1X operation, you must enable 802.1X
authentication. Refer to “5. Enable 802.1X Authentication
on the switch” on page 13-26.
