Test Successful MAB Authentication

Description

This scenario shows how to configure MAB-only authentication. DUT1 uses a correct MAC address.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.215.168.64/24
set interfaces ethernet eth1 address 192.168.100.1/24
set interfaces ethernet eth1 authenticator aaa authentication list1
set interfaces ethernet eth1 authenticator log-level debug
set interfaces ethernet eth1 authenticator mode only-MAB
set interfaces ethernet eth1 authenticator quiet-period 60
set interfaces ethernet eth1 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/YK0MEwtPkTfKefSaHnaiWTXBhjMiblkkA+EH1cOFqSEQTNCkVqpY+DUZsL3CnqT/ktmTpV00oAg==

Step 2: Ping the IP address 10.215.168.1 from DUT0:

admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1
Show 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=0.342 ms

--- 10.215.168.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.342/0.342/0.342/0.000 ms

Step 3: Set the following configuration in DUT1 :

set interfaces ethernet eth1 address 192.168.100.2/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 4: Ping the IP address 192.168.100.1 from DUT1:

admin@DUT1$ ping 192.168.100.1 count 1 size 56 timeout 1
Show output
PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data.

--- 192.168.100.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.643/0.643/0.643/0.000 ms

Step 5: Run the command interfaces ethernet eth1 authenticator show stats on DUT0 and check whether the output matches the following regular expressions:

Step 6: Ping the IP address 192.168.100.1 from DUT1:

admin@DUT1$ ping 192.168.100.1 count 1 size 56 timeout 1
Show output
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=0.424 ms

--- 192.168.100.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.424/0.424/0.424/0.000 ms

Step 7: Run the command system journal show | grep "osdx hostapd" on DUT0 and check whether the output contains the following tokens:

Test Unsuccessful MAB Authentication

Description

This scenario shows how to configure MAB-only authentication. DUT1 uses an incorrect MAC address.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.215.168.64/24

set interfaces ethernet eth1 authenticator aaa authentication list1
set interfaces ethernet eth1 authenticator log-level debug
set interfaces ethernet eth1 authenticator mode only-MAB
set interfaces ethernet eth1 authenticator quiet-period 60

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 U2FsdGVkX18GQEqH6vkZ5JsnEyEpUPAslF+V5Sew0fCI95ZrXoA7K1qdWP/g3Y+tJ+nYmo56HydWVRN2NgMKLA==

Step 2: Ping the IP address 10.215.168.1 from DUT0:

admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1
Show 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=0.226 ms

--- 10.215.168.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.226/0.226/0.226/0.000 ms

Step 3: Set the following configuration in DUT1 :

set interfaces ethernet eth1 address 192.168.100.2/24
set interfaces ethernet eth1 mac '00:11:22:33:44:55'
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 4: Run the command interfaces ethernet eth1 authenticator show stats on DUT0 and check whether the output matches the following regular expressions:

Session User Name                       N/A

Step 5: Expect a failure in the following command: Ping the IP address 192.168.100.1 from DUT1:

admin@DUT1$ ping 192.168.100.1 count 1 size 56 timeout 1
Show output
