Coa
This scenario shows how to enable CoA (Change of Authorization) in a device with 802.1x/MAB authentication.
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 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 set interfaces ethernet eth2 authenticator 802.1x max-retransmissions 2 set interfaces ethernet eth2 authenticator aaa authentication list1 set interfaces ethernet eth2 authenticator coa client 10.215.168.1 set interfaces ethernet eth2 authenticator coa encrypted-secret U2FsdGVkX1/XFHnKsXRB3wCzCUYyYu11AN8EuW6Ss6U= set interfaces ethernet eth2 authenticator log-level debug set interfaces ethernet eth2 authenticator mode only-802.1x set interfaces ethernet eth2 authenticator quiet-period 60 set interfaces ethernet eth2 authenticator reauth-period 0 set system aaa group radius radgroup1 server serv1 set system aaa list list1 method 1 group radius radgroup1 set system aaa server radius serv1 address 10.215.168.1 set system aaa server radius serv1 encrypted-key U2FsdGVkX1/LoYpfHzj3/5O88B//8QiiyhrPR6Vjn2XRrv1VAdF5SU5ovRraNepxPzVx/kpG8efdmrCg70g7vw== set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Ping IP address 10.215.168.1 from DUT0:
admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1Show output
PING 10.215.168.1 (10.215.168.1) 56(84) bytes of data. 64 bytes from 10.215.168.1: icmp_seq=1 ttl=64 time=0.575 ms --- 10.215.168.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.575/0.575/0.575/0.000 ms
Step 3: Set the following configuration in DUT1 :
set interfaces ethernet eth2 address 192.168.100.2/24 set interfaces ethernet eth2 supplicant encrypted-password U2FsdGVkX1+wcf4dIQSqK7lKkxpCw4DMaNWKOmzgU5E= set interfaces ethernet eth2 supplicant username testing set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 4: Run command interfaces ethernet eth2 supplicant show status at DUT1 and check if output contains the following tokens:

Step 7: Ping IP address 192.168.100.1 from DUT1:

PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data. 64 bytes from 192.168.100.1: icmp_seq=1 ttl=64 time=0.365 ms --- 192.168.100.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.365/0.365/0.365/0.000 ms
Note
Send a CoA/Disconnect request from the RADIUS server
On Linux, the FreeRADIUS package includes the
radtest utility, which can be used to send these messages:
