John,

Thanks for ur reply. Can u explain me in detail, what steps I need to take?

Vasu.

Vasu,

You can try:

Router(config)#ip flow-top-talkers

Router(config-flow-top-talkers)#top 10

Router(config-flow-top-talkers)#sort-by bytes

Router(config-flow-top-talkers)#

Router(config)#int g0/1

Router(config-if)#ip route-cache flow

To show the top talkers:

Router# sh ip flow top-talkers

The top traffic generators will be listed at the top.

HTH,

John

John,

I didn't see this message earlier. I will try this and share the output.

Thanks for ur help.

Vasu.

John,

In my router, ip flow-top-talkers is not supported. Any other option?

Vasu

Rock,

I am pasting the Show run int and show int output.

sh run int se1/0:30

Vasu,

Something is using 57k of your 64k line. The netflow will help.

John

John,

ip flow-top-talkers is not supported in my router. Any alternate command?

Vasu

What router do you have?

John,

Router model is 3845 and the IOS version is c3845-advipservicesk9-mz.124-15.XZ.bin

Vasu

Vasu,

I'll take your word for it. I would've thought netflow would've been in that image, but I don't have that particular image to test.

Looks like you'd need:

12.4(25) c3845-advipservicesk9-mz.124-25.bin

to be able to support netflow.

Other than having a sniffer, I can't think of any other way you can configure anything on the router that would show you the traffic.

John
