Re: OT: Catalys 6500 qos policing doubts

Many Thanks, Marc

I have 6800 line cards in the Catalyst 6500 with Sup2T, and just using the
interfaces of these 68xx cards i need to do qos

By the way, i have seen some docs about catalyst qos where this is managed
on egress using queues as you said, translating the dscp ingress marked
values to Cos values, and these Cos to egress queues where some type of
policing is applied... maybe this is the best or most extended solution,
but at this moment i also have this doubt, maybe you can help... the dscp
values yo set at ingress are "internal dscp" values only used by the
catalyst platform or PFC (and then maybe they can not be inspected using a
span or similar)?

Best Regards.
