Is there anyway to test to see if QOS is running properly? -Other than contacting the end user and saying "Hey, how's the network?"
We are have MPLS and the ISP has configured QOS on their side. My side is listed below: --thx
class-map match-any APPS
match access-group 126
class-map match-any BGP
match access-group name BGP
policy-map ETMS
class APPS
set ip dscp af31
bandwidth remaining percent 100
class BGP
priority percent 5
class class-default
fair-queue
random-detect
set ip dscp default
!
int s0/0/0
max-reserved-bandwidth 100
service-policy output ETMS

You could verify that packets arrive on the far side with the marking you expect. You can also use a traffic generator to load one or more classes and see if performance for other classes is as you expect. (NB: this can disturb production traffic.) BTW, when running across a cloud, such as MPLS, if you have asymmetrically bandwidth, you'll likely only be able to stress in one direction.

The sho policy-map command shows that the traffic is being classed but it's going through a MPLS system that I have no control of.
