QOS question in WAN Router

We need to apply QOS on WAN router, 30 % of the bandwidth we can utilize for Voice, Video and Signaling. The below QOS will do the needful or please correct me if my understanding is wrong ?.

Class-map match-all VoIP

match ip dscp ef

Class-map match-all Signaling

match ip dscp cs3

Class-map video-conferencing

Match ip dscp af41

!

Policy-map Edge

class VoIP

class video-conferencing

class Signaling

priority percent 30

!

What Sh commands to test in the other end of WAN side the packets are marked properly?.

QOS question in WAN Router

This will not work. You need to classify Voice, Video and signalling differently..

class-map match-any VOIP

match ip dscp cs5  ef

class-map match-any VIDEO

match ip dscp cs4  af41  af42  af43

class-map match-any Signalling

match ip dscp cs3  af31  af32  af33  cs6  cs7

class-map match-any general

match ip dscp cs1  af11  af12  af13

policy-map Edge

class VOIP

  priority 5000 (choose the value you want to use for your VOIP traffic in Kbps--here its 5MB)

  police 5000000 conform-action transmit  exceed-action drop

class VIDEO

  bandwidth remaining percent 40

  random-detect dscp-based

class Signalling

  bandwidth remaining percent 30

  random-detect dscp-based

class general

  bandwidth remaining percent 1

Then you need to apply your policy to your WAN interface..

interface gigt0/1

service-policy output Edge

To test..

#sh policy-map int gig0/1

QOS question in WAN Router

Thanks for the reply,

I am confused with Bandwidth allocation; we have 100 MBPS WAN link, customer told to use 30 % of the total Bandwidth.

I need to configure 14 MB for voice, 14 MB Video,  2 MB for signaling and 70 remaining  bandwidth let them use for other purpose, Kindly can you please modify  the CLI as per the requirement. My understanding as below please correct me if I am wrong.

policy-map Edge

class VOIP

  priority 14000

  police 5000000 conform-action transmit  exceed-action drop

class VIDEO

  bandwidth percent 14

  random-detect dscp-based

class Signalling

  bandwidth  percent 2

  random-detect dscp-based

class general

  bandwidth remaining percent 70
