Traffic Shaping

jasongr33nway · ‎06-06-2017

I am trying to add a few shaping classification to an auto QoS policy-map and it is not working. I can see the matching packets for each class-map but the shaping is not happening.

I wasn't sure if this policing on the output Auto QoS policy map would be an issue

Hello,

Can you please try a nested service policy-map like this one:

policy-map SHAPING-100Mb
 class class-default
 shape average 100000000
 service-policy AutoQos-4.0-Output-Policy

interface <WAN interface>
 service-policy output SHAPING-100Mb

Hello,

can you post post the output of 'show auto qos' ? The shaping needs to be configured in the parent policy map...
