Re: OT: Catalys 6500 qos policing doubts

Thanks for the information. So I guess it is enabled by default then.
What does a 'show mls qos map dscp' look like?
Are you using mls qos trust? How are you marking on ingress? are you
using mqc? per port? per vlan?

I only ask because you stated that you are doing some PCAPS not seeing changes.

I am splitting up both ingress and egress. It sounds like ingress
isn't working or you would see packtes marked properly.

looking to help, all food for thought and could help with that information.

Regards,

Marc
