Acl Id
This scenario shows how to install traffic policies from received RADIUS messages (using Filter-Id attribute and according to RFC2865).
Test 802.1x Filter-ID ACL
Description
DUT0 is configured with an 802.1x authenticated interface and DUT1 is configured as a supplicant. A traffic policy is automatically configured in DUT0 after supplicant is authenticated.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.215.168.64/24 set interfaces ethernet eth1 802.1x authenticator aaa authentication list1 set interfaces ethernet eth1 802.1x authenticator aaa authorization acl-alias RADIUS_ACL direction both set interfaces ethernet eth1 802.1x authenticator aaa authorization acl-alias RADIUS_ACL priority very-high set interfaces ethernet eth1 802.1x authenticator aaa authorization acl-alias RADIUS_ACL traffic-policy POL1 set interfaces ethernet eth1 802.1x authenticator reauth-period 0 set interfaces ethernet eth1 address 192.168.100.1/24 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 U2FsdGVkX18/cJ8C3pMp6KWYOtDmO2U50QdAU2NgFgIcc1WyW6PTlF+vV/ifqTkPdQjLwqgUMJcnnUAY+THkbw== set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set traffic policy POL1 rule 1 selector SEL_ICMP set traffic policy POL1 rule 2 selector SEL_SSH set traffic policy POL1 rule 3 action drop set traffic selector SEL_ICMP rule 1 protocol icmp set traffic selector SEL_SSH rule 1 destination port 22 set traffic selector SEL_SSH rule 1 protocol tcp set traffic selector SEL_SSH rule 2 protocol tcp set traffic selector SEL_SSH rule 2 source port 22
