[c-nsp] Network mapping...again

[John Neiberger]

We're looking for a dynamic network mapping tool that does not require
a large amount of hand-holding and manpower to manage. I don't care if
this is a free or paid product. Ideally, I'd like something that
autodiscovers the network including L2 and L3 devices, then
intelligently maps them. I used to use Network Node Manager for this
at another job years ago and I liked how it handled mapping. It did
require a few tweaks to get right, but it worked very well. Something
like that would be pretty handy, but we don't need NNM. We just need
the mapping part.

We have too many tools that already require a lot of time to maintain.
I don't want to add another one that is going to take a lot of time. A
reasonable amount of time is expected. I just don't want anything over
time consuming. This is a fairly large network with a large number of
routers and switches, all Cisco.

I just need something that works, and works well, preferably out of
the box. I don't have time to build a grow-your-own solution or piece
together open source stuff.

Any thoughts?
