you need to activate netflow feature

configure terminal
interface FastEthernet 0/1
ip route-cache flow
exit

!

wait some time then

sho ip flow top-talkers

u can also use one GUI to collect and display flows stat such as net flow server (example ManageEngine_NetFlowAnalyzer.exe)

in this case you need to add these cmds:

ip flow-export destination 192.168.9.101 9996
ip flow-export source FastEthernet 0/1
ip flow-export version 5
ip flow-cache timeout active 1
ip flow-cache timeout inactive 15
snmp-server ifindex persist

Hello Tamilvanan,

netflow is technically better

but a simpler way is to use ip accounting:

int wan

ip acccounting output-packets

you can see stats with

sh ip accounting

this can be used to find out a PC using too much resources of performing peer-to-peer

Hope to help
