PFR automatic learning list Inactive ?

Hello Everybody ,

i have one MC/BR and one BR :

Border           Status   UP/DOWN             AuthFail  Version

3.3.3.3          ACTIVE   UP       00:11:12          0  3.0

10.30.21.1       ACTIVE   UP       00:11:10          0  3.0

MY  Goal is the learn some classify traffic automatically and then apply policy for this traffic-class

Configuration ACL

ip access-list extended Defined_PFR_Appl

permit tcp any any eq www

permit tcp any any eq 443

permit tcp any any eq smtp

ip access-list extended icmp

permit icmp any any

Configuration Enabling PFR-MAP for this leanring list

pfr-map Test_MAP 10

match pfr learn list PBR_APPL

pfr-map Test_MAP 11

match pfr learn list icmp

So i really don ´t understand, why i can´t match any access-list on the learn list ?

Hi Junior,

Have you applied the pfr-map under pfr master using policy-rules Test_MAP ?
