I have noticed on occassion, discrepencies between 'match protocol' and
'show ip nbar port-map'

An example is that on one of my routers I can configure within a class map
'match protocol rtp' with little trouble, it will even show up in the
config.
If however I run show ip nbar port-map, there is no reference to RTP.
If I perform the following command > ip nbar port-map ?

I will see RTP as an option, but if run > ip nbar port-map rtp I will
get a unrecogonized command response.

So my question is, if one is asked to do such a task should you check the
port map to make sure the router is doing what you think it is doing?

Secondly if it is not doing what you hope, then you could use a custom-01
with port-map.

Thirdly do you recommend clarfication from the Proctor on this one?

Thanks Simon
