How to mark Jabber traffic

[John Huthmaker]

I just set up a new QoS policy for my offices.  I did a "sho policy-map int g0/0".  I see all the traffic except Jabber video.  Unfortunately I dont have any video phones to test out my policy.  But either way, I need to get jabber to mark its traffic.  I did some googling, and from what I read, jabber does not mark its traffic.

What other options can I use to mark my traffic?  I turned on ip nbar protocol-discovery, but I didnt see anything obvious that pointed to jabber video traffic.  I'm hesitant to do an access list with a port range because I dont want to mark other traffic that could land in the range.

What does the rest of the community do to get over this hurdle?

Hi ,

 you can use an ACL for that.

 As soon as Jabber is both voice and video capable, you can choose to mark it as a voice or video.

 Try this as an example:

access-list 101 permit udp any any range 16384 32767

class-map VOICE
 match access-group 101

policy-map Mark
 class VOICE
  set ip dscp ef

interface range Gigabitethernet 0/0
 description IP Phone port
 service-policy input Mark

Hope this helps.

I had done this a bit ago.  It does seem to work.  But as I expected, it is marking some non jabber traffic.  Its a pretty small quantity so I guess its close enough.
