Question
I'm a bit confused on one part of the article. "STP is the IEEE 802.1d protocol, and it prevents loops in a LAN. Testing this switch port is necessary; enabling STP can create a loop on a LAN." I am wondering how STP prevents loops in a LAN, but enabling STP can create a loop in a LAN? Does that mean it can create a loop if configued wrong?
I was also wondering if you could or have already written an article on Smartports? We just upgraded all of our old hubs to Cisco 2950 switches. I noticed via the web interface that they have something called smartports. I'm not sure what they do or how they work. If you could send me a link or something that would be awesome. Thanks for the wealth of knowledge you provide us.
