Re: 3560 policing

Thanks Carlos. I noticed the stats were all showing up with 0's with the
show policy map interface. I am surprised the syntax is accepted when it
has no real releavance. I would have agree that catalyst QoS on
3750/3560/2960 isn't great to borderline lousy... Not sure where it is on
Cisco's priority list as it hasn't ever worked right.
