Capturing traffic in cisco devices.

[johnleeee]

Hi all,

Id like to ask how I can capture traffic

in Cisco routers? Something like in Cisco PIX firewalls. It is very nice in Cisco PIXs when I can troubleshoot outgoing and incoming traffic throught some interface of PIX. With capture capability.

Any idea?

It's not possible to do such capture on the routers...

PIX has PC-based architecture.

Try to use: debug ip packet command with access-list parameter. Be careful! Do not start just debug ip packet, it can be very difficult for your router.
