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 service ssh
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

Note

IP Filter Rule ACLs:

  • Allow incoming/outgoing ICMP traffic to/from 192.168.100.0/24.

  • Allow management SSH traffic (tcp 22).

  • Allow incoming UDP flows from 192.168.100.2:1234 towards 192.168.100.1:1234.

  • Drop remaining traffic.

Step 8: Run command interfaces ethernet eth2 authenticator show acl rules at DUT0 and expect this output:

Show output
Received ACL type: Filter-Rule.

Rules for incoming traffic:
 1: permit in 1 from any to 192.168.100.0/24
 2: permit in 6 from any to 192.168.100.1 22
 3: permit in 17 from 192.168.100.2 1234 to 192.168.100.1 1234
 4: deny in ip from any to any

Rules for outgoing traffic:
 1: permit out 1 from 192.168.100.1 to any
 2: permit out 6 from 192.168.100.1 22 to any
 3: permit out 17 from 192.168.100.1 1234 to 192.168.100.2 1234
 4: deny out ip from any to any

Step 9: Ping IP address 192.168.100.1 from DUT1:

rtt min/avg/max/mdev = 0.714/0.714/0.714/0.000 ms

Step 10: Init an SSH connection from DUT1 to IP address 192.168.100.1 with the user admin:

admin@DUT1$ ssh admin@192.168.100.1 option StrictHostKeyChecking=no option UserKnownHostsFile=/dev/null
Show output

Test MAB NAS-Filter-Rule ACLs And CoA

Description

In this scenario, DUT1 is authenticated via MAC address and some ACLs are configured. A CoA message is later received from the authentication server that changes the configured ACLs to drop non-ICMP traffic.

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 aaa authentication list1
set interfaces ethernet eth2 authenticator coa client 10.215.168.1
set interfaces ethernet eth2 authenticator coa encrypted-secret U2FsdGVkX1+g3+QLlD5ACLj6q9jU87+dp1hcvaekCvA=
set interfaces ethernet eth2 authenticator log-level debug
set interfaces ethernet eth2 authenticator mode only-MAB
set interfaces ethernet eth2 authenticator quiet-period 60
set interfaces ethernet eth2 authenticator reauth-period 0
set service ssh
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 U2FsdGVkX18KR/T0GDa+M4KsgN1En1ePgkm/R0aAtguriqfSploNAHgQxD/TKIZzV6xyj3CN7cImcUnZiHuDDQ==

Step 2: Ping 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.

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.363/0.363/0.363/0.000 ms

Step 3: Set the following configuration in DUT1 :

set interfaces ethernet eth2 address 192.168.100.2/24
set interfaces ethernet eth2 mac 'de:ad:be:ef:6c:1f'
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 4: Ping 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 = 0.369/0.369/0.369/0.000 ms

Step 5: Run command interfaces ethernet eth2 authenticator show stats at DUT0 and check if output matches the following regular expressions:

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.

      Failed filter : 0

Note

IP Filter Rule ACLs:

  • Allow incoming ICMP traffic.

  • Drop remaining incoming traffic.

NOTE: outgoing traffic is allowed.

Step 7: Run command interfaces ethernet eth2 authenticator show acl rules at DUT0 and expect this output:

Show output
Received ACL type: Filter-Rule.

Rules for incoming traffic:
 1: permit in 1 from any to any
 2: deny in ip from any to any

Step 8: Ping IP address 192.168.100.1 from DUT1:

rtt min/avg/max/mdev = 0.271/0.271/0.271/0.000 ms

Step 9: Init an SSH connection from DUT1 to IP address 192.168.100.1 with the user admin which is going to fail:

admin@DUT1$ ssh admin@192.168.100.1 option StrictHostKeyChecking=no option UserKnownHostsFile=/dev/null

Step 10: Expect a failure in the following command: Initiate a udp connection from DUT1 to DUT0 and try to send some messages between both endpoints

admin@DUT0$ monitor test connection server 1234 udp
admin@DUT1$ monitor test connection client 192.168.100.1 1234 udp source-port 1234

Step 11: Expect a failure in the following command: Initiate a udp connection from DUT0 to DUT1 and try to send some messages between both endpoints
