4500 QoS DBL and marking

Hi,

When you use AutoQos on the 4500 it configures DBL with an "service-policy output" command on the interface level.

policy-map autoqos-voip-policy
  class class-default
    dbl

interface GigabitEthernet3/1
 service-policy output autoqos-voip-policy
 qos trust cos
 auto qos voip trust
 tx-queue 3
   bandwidth percent 33
   priority high
   shape percent 33

The issue I have is that I want to use an ACL to Mark voice traffic with EF which uses a "service-policy input".

As far as I am aware, you can't have an output and an input service-policy on the same interface.

policy-map QoS
  class class-voice
   set dscp ef
  class class-default
   set dscp default

class-map match-any class-voice
  match access-group 100

access-list 100 permit ip 10.10.10.0 0.0.0.255 any

interface FastEthernet0/1
   service-policy input QoS

Can anyone offer any help ?

Thanks, Thomas
