Hello,
I did some searching through the Archives and the last time that i have
seen that is issue was brought up was November of 2011, but it was not
resolved. I'm hoping someone can help me resolve my issue here.
I am trying to implement class-based cRTP on a Frame-Relay link with
fragmenting being done in the map-class. I can see where my RTP packets are
being matched in the output of show policy-map interface , but the cRTP
counters remain at 0. Below is my configuration , any help is very much
appreciated.
