Need to run a packet capture using Wireshark to monitor a few ports on a Catalyst 3550 switch

I am looking for detailed instructions on how to setup the SPAN, and specify ports to be monitored.

I am familiar with connecting a PC to the Switch and capture the packets using Wireshark

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Assuming the traffic you want to capture is on the f0/6 port:

monitor session 1 source interface f0/6

Open in new window


And your wireshark host in on f0/3

monitor session 1 destination interface f0/3

Open in new window

If you need a very flexible Packet Sniffer that has Advanced rules for Port, IP, MAC capturing, consider using Comm View (tamosoft.net). This is a very advanced packet sniffer that I use myself.

Thanks John.
I was going to send a PM to Nader... but I didn't want to overstep. :-)
