Configuring an Authenticator and a Supplicant Switch with NEAT

Configuring this feature requires that one switch outside a wiring closet is configured as a supplicant and
is connected to an authenticator switch.
For overview information, see the
Access Topology (NEAT)" section on page
The cisco-av-pairs must be configured as device-traffic-class=switch on the ACS, which sets the
Note
interface as a trunk after the supplicant is successfully authenticated.
Beginning in privileged EXEC mode, follow these steps to configure a switch as an authenticator:
Command
Step 1 configure terminal
Step 2 cisp enable
Step 3
interface interface-id
Step 4
switchport mode access
Step 5
authentication port-control auto
Step 6 dot1x pae authenticator
OL-21521-01
Purpose
Set the number of seconds between re-authentication attempts.
The 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.
Return to privileged EXEC mode.
Verify your 802.1x authentication configuration.
(Optional) Save your entries in the configuration file.

11-29.
Purpose
Enter global configuration mode.
Enable CISP.
Specify the port to be configured, and enter interface configuration
mode.
Set the port mode to access.
Set the port-authentication mode to auto.
