Test CoA Disconnect 802.1x Peer

Description

In this scenario, three parties are actively involved: an authenticator (DUT0), a supplicant (DUT1), and an authentication server (DUT2). Once the authentication is successfully performed, DUT2 sends a CoA/Disconnect message to terminate the active session.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.215.168.64/24
set interfaces ethernet eth2 address 192.168.100.1/24
