RE: ip rtp priority on frame relay

The reasoning for the match is the starting port # (16384) and the # of
ports to include (16383), and 16384 + 16383 = 32767, which is the high
end of the range.

16383 ports starting with # 16384 are for H.323 voice
16383 ports starting with # 32768 are for H.323 whiteboard
16383 ports starting with # 49152 are for H.323 video

Just in case you have to match other things. :)

As for matching on ip prec 5 or DSCP EF, you SHOULD be cool with that,
but it will depend on your application (just to be safe).

For voice traffic the range is 16384 to 32767, (just remember 16384 x 2
-1), you can also match on precedence 5, or dscp ef if using CBWFQ.. but
for rtp priority, (for reasons I am still unclear on..), all the docs I
have read say to match on 16384 and 16383... For RTP use:

map-class frame MYMAP

Frame ip rtp priority 16384 16383 45

Bandwidth 32

RTP example:

Map-class frame MYMAP

Frame bc 640

Frame cir 64000

Frame be 0

No frame adaptive

Frame fair-queue

Frame fragment 80

Frame ip rtp priority 16384 16383 45
