packet capture

_maurice

Is there a cisco debug command that will run a packet capture and save the output as a libpcap file so it can be viewed in wireshark?

You can do this with dynamips/dynagen: http://www.dynagen.org/tutorial.htm#_Toc193248010

I'm not sure if there's a debug command that does something similar, but maybe that will do what you need.

Thanks dynamik, but I am talking about in a real world scenario. Maybe you're in another state, and you need to run a capture on a live cisco without unplugging wires. Something along those lines.

Thanks

You can try IP Traffic Export

Thanks Mike! That supportwiki.cisco.com link in the CCNA thread has exactly what I was looking for.
