Configuring Switch As A Supplicant - Cisco Catalyst 4500 series Administration Manual

Chapter 46 Configuring 802.1X Port-Based Authentication
------------------------------------------------------
device-traffic-class=switch
show running-config interface is the only command that informs you that the smart macro has been
applied after the supplicant switch is authenticated:
Switch
Interface

Switch# show running-configuration interface gi 5/23

end
Switch#
NEAT changes the port configuration on the authenticator switch. So, to perform ISSU from one version
that supports NEAT to another that does not support NEAT, you must first deactivate NEAT on all switch
ports for ISSU. Similarly, NEAT cannot activate when ISSU is in progress. If a supplicant switch tries
to authenticate during ISSU, authorization would fail on the port.

Configuring Switch as a Supplicant

The Catalyst 4500 series switch does not support supplicant switch functionality. The following
Note
supplicant specific commands are mentioned for a quick reference. For more details, see the
Catalyst 3750 Switch Software Configuration Guide.
To configure a switch as a supplicant, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# cisp enable
Step 3
Switch(config)# dot1x credentials
profile
Step 4
Switch(config)# sername suppswitch
Step 5
Switch(config)# password password
Step 6
Switch(config)# dot1x supplicant
force-multicast
OL_28731-01
# show authentication session
MAC Address Method
0024.9844.de23 dot1x
Purpose
Enters global configuration mode.
Enables CISP.
Creates 802.1x credentials profile. This must be attached to the port that
is configured as supplicant.
Creates a username.
Creates a password for the new username.
Forces the switch to send only multicast EAPOL packets when it
receives either unicast or multicast packets.
This also allows NEAT to work on the supplicant switch in all host
modes.
