[cisco-voip] VoIP and Switch and Policy Maps

[Erich Novak]

Hi,

since IOS 12.2.40( not sure but somewhere in this timeframe)  these where automatically created by AutoQoS, before there was no policing for voice traffic exceeding 320kbps and for control traffic at 32kbps.
All it does is setting the PHB from EF to a lower dscp value

Betreff: [cisco-voip] VoIP and Switch and Policy Maps

Hi,

I've been combing through our switches and I've noticed that some switches, not all, have a class-map and policy-map configured.  I've pasted in both configs below along with most of the config on the switch interfaces.  The switches without the maps configured, have the same interface config except for 2 statements:  priority-queue out and service-policy input AutoQos-Police-CiscoPhone.

Only sites with PRIs have the maps configured, but not even all of them, and at one site, some switches have it and others don't.

Any quick explanation as to what is going on here?  Should all our PRI sites have this configured on the switches?  What about the non-PRI sites?

Thank you!
jeff
