[cisco-voip] VoIP and Switch and Policy Maps

[Jeff Ruttman]

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
