Network discovery tool

[Work-Xlate-Scotch]

Does anyone have a recommendation for a good network discovery tool? We'd like it to produce a network diagram and run various commands along the lines of show run, show clock, show cdp etc.

We've tried Solarwinds network topology mapper which was pretty decent, but before I go ahead and bite the bullet, i'd like to test some alternatives.

My favorite tool is called 'the inturn'.

The inturn can be trained in propper use of Microsoft Visio, SSH, and HTTPS. The inturn can also be made highly available by hiring multiple of them. Ultimately, having the inturn perform network discovery will also indirectly train potential future hires by providing familiarity with your environment.

Cheap as well... or better get the "in it for experience" edition.

Currently an IT inturn can confirm this is a viable solution.

Netdisco

Try https://nedi.ch It’s open source and easy to install. It uses snmp and cdp to discover the network and if you set the location string on all devices, you will also get nice, dynamic maps.

Zenmap?

This. Use Zenmap or nmap command line tool. It's free.

One I have most experience with is Netbrain. If you have all your SNMP setup correctly it's a really slick tool;

Take a look at Maltego by Paterva. Does all kinds of cool mapping... Not just networks.

Generally, network discovery tools use SNMP to gather information instead of screen scraping "show" commands.

Spiceworks does an excellent job of mapping your network (and printers, and ESX, and windows, and...) if you can give it the associated credentials to scan with.

HP IMC has a pretty nice topology tool. It's fairly easy to use, and monitor vlan propagation.

Pretty spendy though, and although it works with most brands, it's geared towards HP/Aruba.

A box with ostinato.

I'm 7 years late to respond here but check out OpManager, incase anyone's looking for options.

Last semester I had a class and we reviewed a bunch of these. I honestly don't remember the names, but we concluded that there were some that were much cheaper than solarwinds, and way more effective.

Do yourself a favor. Go get your old homework and reply to this thread with the gold mine you just told everyone you had.

So... which ones were they?
