Ok, thanks for the insight. I was reading about the Cisco Discovery Protocol (we just bought some Cisco switches and I am learning how to configure them) and read something on the wiki's about the LLDP being open and not under the control of any one company. We use a very simple protocol internally where we send simple UDP messages with xml tags so we can figure out what devices are on the network. I was wondering if there was a more standard way to do these things. I like standards, especially open ones.
