MQC question

[Maurice Ball]

Could someone please help me with the following QoS issue? I setup a small QoS lab to get familiar with the MQC setup. The problem I am having is I can't get the packets to go in to the correct queues.The packets are being marked correctly when they enter the router but they are not going in the correct queues when they are being queued to leave the router. It looks like all packets are using the class-map  "class-default".Could someone give me some insight to why this is happening? The configuration is attached and also the output from the show policy-map on both interfaces. Thanks in advance.

Hi Maurice,

Can you remove the section of configuration below and retest?

policy-map SHADE_2MB
 class All_TRAFFIC
    shape average 2000000
  service-policy PRIORITY

It is calling the same policy-map, and I'm wondering if it's interfering with the results.

Cheers,

Mike

Hi Mike,

I remove the nested policy-map as you suggested but I am still getting the same results. The packets are still not queuing correctly.
