Video Signaling versus Video media in Qos

[anilkumar.cisco]

Hello Friends,

in Enterprise LAN Qos what is difference between Video Signaling and Video media segregation..

Both are same or both are different, I am not able to conclude it..

if one someone  says you have to Allow 20Mbps for Video signaling

and allow 20 Mbps for Video media on the 3750 switch

then how I will segregate the both traffic.

Below is the sample of ACL prepared by me to bifurcate voice bearer and signal traffic and I am confused with video signaling and video media packet segregation.

ip access-list extended voice-signaling

permit tcp X.X.X.0   0.0.0.255 any range 2000 2002

permit tcp X.X.X.0   0.0.0.255 any eq 5060

permit udp X.X.X.0   0.0.0.255 any eq 5060

ip access-list extended voice-bearer

permit udp X.X.X.0     0.0.0.255 any range 16384 32767

class-map match-all voice-bearer

match access-group name voice-bearer

class-map match-all video-traffic

match access-group name voice-bearer

match ip dscp af41

class-map match-all voice-signaling

match access-group name voice-signaling

policy-map voice-port-policy

class voice-bearer

police XXX000 8000 exceed-action drop

class voice-signaling

set dscp cs3

police XXX00 8000 exceed-action policed-dscp-transmit

class video-traffic

set dscp af41

police 200000 8000 exceed-action policed-dscp-transmit

class class-default

set dscp 0

and without segregating Data traffic in ACL.. how it will go to class default??

the data is not explicitly defined so it will drop out the bottom of your policy map and will be set to dcsp=0 in your config.

voice signalling is SIP in your case, which needs very little bandwidth, you definitely do not need 20Mbps for it.

thanks for your reply..

So data will be sent via dscp marking of 0 and it will not dropped?

I am confused with Video signal traffic, how should I segregate it

and how video signal and media traffic I will segregate?

Kindly suggest.

Also , the video call will have between two sites via CUBE, and between Jabber and 9971 IP phone.. So I think we need to mark H.323 signaling also here..
