Tool to draw Network Topology Map

Unanswered Question
Jun 9th, 2007

Dear all,

we have several small branch officies with up to 10 Switches each.

I'm looking for a cheap (better free) software that can do the following.

- Discover the Switches

- Draw a map with the information from CDP to see how the switches are physically connected / linked to each other (at which ports/interfaces)

Optional: See how spanning tree has blocked the redundant links

Any suggestions are welcome

I have this problem too.

To discover your network you may wish to adapt a script you can find here:

It can give you a hostlist and if you adapt it a list of what port connects to what port.

Displaying is a little more complicated. To give it a sensible layout it needs a lot of (manual) work.
