How do I mark VLC streams with proper DSCP markings

I have a server using VLC to stream h264 video and mpeg4 audio to a multicast address.  VLC doesn't seem to mark the packets at all.  What can I filter on in an access-list to mark all that audio/video traffic as something appropriate such as af42?  I tried an access list that matches everything from that IP address... but that marks way to much traffic.

Thank you,

Tod

Hi

You could use NBAR (match procotol rtp in the class-map):

Or since you have control of the server use the target mcast address in an ACL.

Thanks.  We just used an access list to match all traffic destined for the multicast address.    It's working perfectly.
