Hi All,
Just wondering if any one could give me a hand. I'm trying to 'Mark" VoIP traffic on the out bound interfaces on a Cisco 6509 and a 4507. Based on what I have read, the recommend why to Mark VoIP traffic on a router is with this command:
class-map match-any MarkRealTime match ip rtp 16384 16383
policy-map MARKING class MarkRealTime set dscp ef
This works great for routers such as 7206 or 2811, but with a 6509 (switch) I get an error stating "Match ip rtp is not supported for this interface" and the 4507 (switch) doesn't support the command at all. Any ideas on either an alternative method that will work or a work around. The interfaces I'm trying to use are standard routing Gig interfaces.
Thanks
Marc
