SNMP and CDP

I’m trying to do an audit on a Windows based network and the software that we are using to discover the network and try to map it is not finding all of the nodes. It is missing at least one switch and the few things it does find it will only give me IP address. When I say it is missing things though, it does show me that it is unidentifiedbut won’t tell me anything else. I ran Advanced IP Scanner next to it, which found the “missing” nodes and would tell me their manufacturer and IP address. I talked to a rep from the software company and he told me to make sure snmp and cdp were enabled on all devices. Do I really need to go through and make sure of this though when I can account for all routers, computers, servers, and switches with Adv. IP Scanner but not with their software?

A pentesting software of some sort is probably what you're looking for. I know nessus is pretty good at operating system enumeration.
