Policy Map Help.

[Alex Li]

Hello All,

I am trying to create a policy map, that will match all my SAN replication traffic and limit that traffiic on the interface to 80 Mb/sec.         

1. I have created the ACL.

      ip access-list extended Gue-SAN-Traffic

      permit ip 172.20.100.0 0.0.0.255 host 172.20.147.10

      permit ip 172.20.100.0 0.0.0.255 host 172.20.147.11

      permit ip 172.20.100.0 0.0.0.255 172.20.147.0 0.0.0.255

2.  I have then created the policy map.

     policy-map Gue-MPLS-policy

      class Class-Gue-SAN-Traffic

         police cir 15000000 bc 2000000

         bandwidth 80000

         shape average 384000

3.  I have  then applied to the interface, outbound.

But for whatever reason, its not working. Can anyone see what I am foing wrong ?

Cheers

policy-map Gue-MPLS-policy

      class Class-Gue-SAN-Traffic

         police cir 15000000 bc 2000000

         bandwidth 80000

         shape average 384000

With the policy, you're policing traffic to 15Mb, guaranteeing a bandwidth of 80Mb, but your shaping to 384k. If you're wanting to restrict your traffic outbound, you can either shape or police. I recommend shaping, so change your policy map to the following:

policy-map Gue-MPLS-policy

      class Class-Gue-SAN-Traffic

         bandwidth 80000

         shape average 80000000

HTH,
John
