QoS - Video

Hi,

I have two offices of ours connected via 2MBps leased curcuit.This link is used for data.When we do Video conference the video/voice packets also run thru this.I would like to implement QoS, so that i can allocate a prefixed bacndwitdh for Video and monitor it.

My main aim is seperating the the data & video/voice traffic..

Can you please send me some sample configuration for this...

regards

Re: QoS - Video

Hi!

I do it on a very simple way.

I split voice and data in seperat VLANs and so I get subinterfaces. On these subinterfaces I do a rate-limit (either just for marking or for marking and policing)

i.e.:

interface FastEthernet0/0.10

rate-limit input 256000 48000 64000 conform-action set-qos-transmit 10 exceed-action set-qos-transmit 10

interface FastEthernet0/0.20

rate-limit input 256000 48000 64000 conform-action set-qos-transmit 20 exceed-action set-qos-transmit 20

************************************

I do a Policy-Map with the Voice with LLQ and Data with RD.

class-map match-any DATA

match qos-group 10

class-map match-any VOICE

match qos-group 20

!

!

policy-map QOS

class VOICE

priority 256

class DATA

bandwidth 1244

random-detect

shape average 1750000

class class-default

fair-queue

random-detect

shape average 1750000

********************************************

Then on the Main Serial link I just put the

interface Serial0/0

service-policy output QOS

*********************************************

Hope that helps

cheers
