Dear Sir/Madam,
Our ISP has one Cisco Systems Router. They asked me to capture the UDP Packets which are sent to the Router (i.e. Destination Address of the IP Packet is Routers IP) .UDP Port is 50551. Please help me to do these things.
Can i use RMON/SNMP ? Please help me to solve these problems.
Thanking you sir.
P.Raja Reddy.

There are creative ways to do this from the CLI, but you really need a packet sniffer to do this.

Sorry but I could not understand what you mean by capturing packets. SNMP just helps you collect desired info from the router but does not help you to count the UDP packets sent through interfaces.
I you want to see the packets for the time being; using sniffer type programs can help you.
Just to see packet count, creating an access-list and letting the rest go, would give you amounts:
!
access-list 100 permit tcp any host
access-list 100 permit ip any any
!
show access-list
