Not seen problems turning on mls qos.
We have on the physicals :-
Int gi1/1
mls qos vlan-based
mls qos trust dscp
and a typical service policy looks like :-
policy-map 10MegPolice
  class class-default
   police 10000000 26000 32000    conform-action transmit     exceed-action 
transmit     violate-action drop

what do you mean you don't classify?

Ian

6500 platform.

Last time we had 'mls qos' enabled we had massive speed/packet loss issues
with interfaces over 40% utilization since we don't classify traffic.

Is there any possible issues you might see?
