(for me) one of the great strengths to RANCID is its simplicity. it's capable of capturing information about your entire network into a single directory full of plain text files. which means, that it's super-easy for a non-coder like me, to "grep -i <serial-number>" to find out where that last piece of equipment was installed. of course, if you want to get fancy, you can dump this into a database, but ... then you're already much smarter than i am ...
so, it becomes really simple to figure out which interfaces are mis-configured as well (ie. half-duplex instead of full-duplex) but looking through this sort of data as well.
as an aside: one of the best presentations i've ever read was: Managing IP Networks with Free Software
i'd encourage you to spend the time reading this too; not because of the tools that's mentioned (that's just btw...)
but because of the thinking processes that's mentioned. and hopefully that will open up the floor for more discussion ... :-)
