Re: QoS and Remarking out of contract traffic to CS0

Unanswered Question
Jul 1st, 2009

Hi,

My question is say that I am using CBWFQ and matching critical data traffic with af41 in a class-map and in the equivalent policy-map giving it a bandwidth of 2Mbps.

How do I remark the out-of-contract critical data to CS0 so that it will fall into the default-class.

Thank you,

InternetB.

I have this problem too.

To expand upon what Andrew posted, you'll need to match and classify upon ingress to accomplish what you describe. This assumes you only have one ingress interface that feeds the egress interface. If you have more than one ingess, what you describe can't be performed, although you could remark or drop out-of-contract packets within the egress policy.

e.g. one ingress to one egress

(NB: syntax likely incorrect)

class-map match-all critical-traffic-in

match ...

clas-mpa match-all critical-traffic-out

match dscp af41

policy-map ingress

class critical-traffic-in

police 2000000 conform-action set dscp-af41 exceed-action set dscp-be

policy-map egress

class critical-traffic-out

bandwidth 2000000
