QoS for VOIP/Video help

JG1978
Level 1
Level 1

We run video and VOIP in our network but I am unsure if our QoS is working correctly.

 

I have done some research but when I show our service policy output, we are only getting matches on "0" and "6"

.....from what I read on wiki:

 

https://en.wikipedia.org/wiki/Type_of_service

IP Precedence "6" should have to match the markings of CS6 or 48 but I do not see those on our policy map.........what is causing everything to be either class 0 or 6 in my config?

 

 

Here is our class map/Policy config:

 

class-map match-any P1
 match ip precedence 5
 match ip dscp ef
 match protocol rtp audio

!
class-map match-any P2
 match ip precedence 4
 match protocol h323
 match protocol rtp video
 match protocol rtcp
 match protocol rtsp
 match ip dscp cs3

!
class-map match-any P3
match ip precedence 2 3
match protocol sip
!
policy-map VOIP_VIDEO
 class P1
  priority percent 40
 class P2
  bandwidth percent 20
 class P3
  bandwidth percent 20
class class-default
 fair-queue
 random-detect


policy-map QoS_Parent
 class class-default
  shape average 16000000
 service-policy VOIP_VIDEO

Are all your network devices set to trust any QoS markings and pass them on, if not, they'll re-mark everything to the default (0) which is where all your traffic is.

Have a good read through the Enterprise QoS Solution Reference Network Design Guide for some configuration examples of how you should consider configuring your environment.
