Hello Friends,
with regard to the Qos.. I am little bit confused with below things..
1. what is difference between video media and video signalling..
I know how to categarize the voice traffice and media in Qos as follows:
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
and to categorize Voice media we used the below access list.
ip access-list extended voice-bearer
permit udp X.X.X.0 0.0.0.255 any range 16384 32767
Now , My question,
How I will categarize the video media traffic..
is the below class map is good to use for video media or video signaling
class-map match-all video-traffic
match access-group name voice-bearer
match ip dscp af41
Also, my video traffice is of jabber and normal Cisco 9971 IP phone traffice, so it will be categorize as
a) Interactive Video (general guideline\standard from Cisco to mark voice with a dscp 46 or ef, Interactive video 34 or af41)
or
b) Streaming Video (Streaming video as dscp 32 or cs4)
so , I am confused with marking of the traffic..
and also,
what is difference between marking of data traffice to best effort versus marking it default unconditionally..
Kindly advise.
Best Regards
Anil Singh

the last method shared by you is NBAR..
and I want to it in ACL..
Can you cross verify pls.. and how can I used in Ethernet switch module of the Cisco 2900 router pls..

I am doing segregation of voice traffic from Data and voice vlan based on access list if you check my configuration carefully and calling in on specific class in order to segregate video and voice traffic.
here video traffic I am considering from Cisco 9971 IP Phone and Jabber PC attached to the phone.
ip access-list extended voice-bearer_voice
permit udp X.X.X.0 0.0.0.255 any range 16384 32767
ip access-list extended voice-bearer_data
permit udp X.X.64.0 0.0.0.255 any range 16384 32767
class-map match-any voice-bearer
match access-group name voice-bearer_voice
match access-group name voice-bearer_data
class-map match-all video-traffic
match access-group name voice-bearer
match ip dscp af41
So I don't think I will get confused here.. because in policy map , I am calling two different type of class..
One with Voice traffic i.e. general voice traffic from Cisco IP Phone attached to the port plus any voice traffic generated from Data vlan i.e. jabber here because by default jabber will not marked it packet from any dspc value thus its voice & Video traffic will be treated as normal voice traffic as per my access list and class map , because its video and voice will fall under my voice bearer class where I am saying match-any.
Now, My confusion is , such type of marking is not possible via the sample configuration which you had shared with me , because it will not understand any voice traffic from data vlan which jabber originate because jabber will not do any marking of packet from the source.
class-map match-all Video
match ip dscp af41
class-map match-all Voice
match ip dscp ef
class-map match-any signal
match ip dscp cs3
match ip dscp af31
if my above understanding is correct, then what would be alternative, where I don't want to any type of changes in Windows PC and CUCM , in order to instruct jabber to send packet with marking.
I want ever thing to be default but should treat jabber atleast voice or if possible jabber video also..
and how the similar thing we can do in Etherswitch module as well..
Hope you understand my requirement.

Hi
Jabber application on windows isn't marking the traffic. Now to mark it, you need to make a configuration on your switch based on acls, medianet or using NBAR to recognize the protocol (match application...).
Make sure the technology you'll use (NBAR, Medianet) is compatible with your devices platform and IOS version.
Here some documentation about medianet that can help:
https://www.cisco.com/c/dam/en_us/solutions/medianet/docs/2_4_deployment_guide.pdf
On your router with etherswitch module, you can also apply policy-map like your doing in your switches.
