I had a student recently who was trying to remember what protocol used udp
port 53, and I showed him how to do a quick lookup with NBAR.
R13#show ip nbar port-map | include udp 53
port-map dns udp 53

Hi Marvin,
I just worked out the numbers from my original solution
and found that I was wrong. I also just sent another post that explains in
detail
how to figure out what values to use.
Re: FTP-data, I thought (assumed) that the statement, match protocol ftp,
matches, by default, both the control and data channel. If that's not the
case,
how would I know that?
I check the command reference and it didn't say one way or another.
Is this one of those things that the only way to know is to test it?
