Re: OT: Catalys 6500 qos policing doubts

I am still in travel. Sorry for delay. I can get to this probably on the
weekend but two resources I can suggest that may help for understanding the
syntax, theory, etc. are

This is based off 3560/3750 architecture. 6500's are much different beast
and also dependent on the line card. I highly recommend getting a
cisco365.com account and viewing campus QoS and downloading the slide. Deck.

I am not copping out and will for sure work on this over the weekend. I
could benefit from the exercise as well.

Marc
