Viewing traffic details on an interface

Unanswered Question
Apr 24th, 2007

Hi,

I need more details of what is going over my serial interface on my router. I cant remember what the command is to enable logging on an interface so it grabs which protocols are going through it. Can anyone help?

thanks

Mick

I have this problem too.

Mick,

You need to use ip nbar protocol-discovery command on the interface for getting the protocol statistic

you can also configure netflow globally and use the command ip route-cache flow under the interfaces and use either netqos or netflow analyser to analyse the traffic flow

HTH, rate if it does

Hello Mick,

Which router do you have and what is the IOS you are running on it.

Try enabling " ip accounting " on the serial interface and should show you the desired results.

If you want granular reports, check the netflow support on your routers which will list all the top talkers along with the protocol being used.

HTH,
