Yes, the policy must be applied to an interface/sub-interface for QoS to take affect. Take a look at the QoS SRND for specific examples. Look under WAN Aggregator QoS Design -> WAN Edge Link-Specific QoS Design.

Re: map-class frame-relay , policy map

Great....thank you for your time and help

greatly appreciate it..

Quick question about fair-queue.

should this be set on the interface as well, as it sits now there is no fair-queue on the serial interface

Re: map-class frame-relay , policy map

The fair-queue command is not necessary on the serial interface. The command in the policy map for class class-default will fair-queue all traffic not in the 256/128KVoice class.

Re: map-class frame-relay , policy map

Hello,

Will QOS will work in this way  where class is put on WAN interface where it should be service  policy.

router#sh run interface Se0/0/0.1
Building  configuration...

Current configuration : 239 bytes
!
interface  Serial0/0/0.1 point-to-point

bandwidth 2048
ip address XXXX
ip nat outside
frame-relay  interface-dlci 555
  class COS-OUT-S0/0/0.1   
end

COS-OUT-S0/0/0.1 is defined as policy map  with class of voice and video.

When checking on WAN int #sh policy-map  interface  Se0/0/0.1 , can see output of service policy input/output with policy map  recpective classes and packets match entries.Is  QOS working with this  configuration?

Appreciate any input on this.

Regards,

Brajesh.
