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..
