We want to know which the the ports used by one edge location router ( one serial and one fasteth port only ), by monitering the serail port or by it's fasteth port. As it is a edge router any interface will give the same result as all default traffic is routed to serial interfaces. I have tried command to check cache entries
# sh ip cache flow
This command shows source , destination IP and ports , but there is some pre-requisite for this command to work. I didnt get what exactly is that pre-requisite. any link on cisco.com or if any other way to find out ports those are used by applications at that location which cross router ?
