Finding the host which is sending traffic on a particular port?
An internal user on my network has a virus and is sending data on a particular port. What's the best way to figure out which user it is? I can connect to a switch that I know the data is going through, and I know the port number.

If you know the switch and port number then you have a couple of options. You can put a packet analyzer on the switch, SPAN the port and look at the packets. It will show the source IP (which will be the PC's IP). If you want to stay Cisco, find the MAC address learned on the port.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
