I'm looking for some free software that will allow me to scan my network for devices and then it plot the topology in a diagram.
There are tools that you can get that just allows you to draw your network manually. I want it to pick up all our hp switches and show that they link to a core switch.
Any one come accross any think out there????

Blimey if there is such a thing out there I want it too - I had to do my last network schematics in Visio and it took ages!
3COM have a bit of software that will map your network for you that's free called Network Supervisor.
3COM Network Supervisor download
You can use it without registering, but the registration is free if a little confusing.
Give it an IP range and it will find all the network devices on it and map them out for you.
Yikes this looks good!
sounds impressive
Well I've got it installing now on my test setup.
Let us know how you get on.
It's a bit basic in terms of the graphics used to create the map but the great thing is you can call up the mac address of any station and it also shows the stress it's under on the network.
Can you post some screen shots?
Just tried but for some reason the box showing the remote desktop comes out black when I do a screen grab. Just going to try a different program.
No, just tried ScreenHunter and still getting a black box where the 3Com window is.

Oh, I got all those last week.Can I also have next weeks winning lottery numbers, a Ferrari and wake up to find my wife has turned into Kelly Brook!
Here's a screengrab of the 3COM software:
Like you say its a bit basic
The 3Com Software works best with 3Com Switches, in fact to get it free you used to have to register a 3Com Switch not sure if that still applies.
HP's software does a reasonable job with HP's but similarly fails to detect others as anything more than a cluster of nodes.
In order to create a meaningful diagram automatically you need switches with a common discovery protocol (HP & Cisco fell out a couple of years ago and stopped supporting each others), the cheaper manufacturers do not have any at all (they don't want to pay license fees to use them) your SNMP needs to be enabled, the community strings must all be the same and preferably the same version of snmp needs to be used.
The sofware needs to understand all of the MIB's of ALL of the switch manufacturers so that the mac tables can be extracted and the inter-connects calculated.
Most of the more sucessful commercial products such as LanSurveyor rely on good SNMP and agents installed on nodes attached to each switch in order to work out how each switch is connected together and which nodes connect to which switch.
The closest to the Utopia requested in this thread under the FREE label has already been posted elswhere on Edugeek - http://www.mikrotik.com/thedude.php
It still has problems finding everything, however it's the best that I have seen for less than the £1200 that LanSurveyor want.
