In the previous post I talked about a situation where a simple configuration issue on a couple of ethernet switches was causing a serious problem for the connected users. I failed to mention that I used one of the tools from the Engineer's Toolset to diagnose and resolve this issue.
A lot of you are probably familiar with using the Switch Port Mapper. This tool is a great time saver anytime you need to locate or document user connected to your switches. Something you may not know is that you can also configure Switch Port Mapper to display settings for speed, duplex, current traffic, and more.
Another key point to mention is that when you're looking at the Switch Port Mapper and you see more than one MAC address on a port, there is most definitely another switch plugged into that port that should be mapped as well.
