Nedi is a lifesaver. It works on L2, unlike HPOV. It is a huge perl 
script that connects via snmp or telnet to one switch/router then uses 
CDP to traverse the entire network.
The BEST part: it maps mac/hostname -> switchport. This, IMHO, is the 
most important information ever. Knowing where a host actually lives has 
made my life _much_ easier.

Note: I started using this ~1 year ago. My name is on the website's news 
page because I wrote a little code to make it parse port listings for 
cisco's "secure ports." I'm not giving biased info, I'm just a user :)
