Hi Everyone,

I have a question regarding searching of DocCD. In Vol1 Lab 21.2, it asks
for traffic shaping for all traffic other than the H.323 voice traffic. Not
having worked much with voice I didn't know which ports H.323 use and
couldn't find them on the DocCD.

The only thing I could find was the nbar port mapping:

R7#sh ip nbar port-map | inc h323
port-map h323                     udp 1300 1718 1719 1720 11720
port-map h323                     tcp 1300 1718 1719 1720 11000 - 11999
R7#

The DSG uses udp 16384 - 32767, so I did some more digging around and found
that after the H.323 call is setup, RTP ( udp16384 - 32767) is used to
transfer the voice traffic which matches the DSG ports.

In the real lab, I probably would have used the nbar port mappings and lost
points. Even using the DocCD search engine, I could still only find some
obscure  references in voice documents for those ports.

So my question is, how would I go about tackling problems similar to this in
the lab where I'm not familiar with 'out of blueprint' topics such a voice
protocols? Or is everything fair game and I'm expected to be familiar with
them?

Thanks
James
