Is there some simple utility to automatically create a network map?

Question

Computer networks

There are a bunch of switches within the same broadcast, you need to remove them from the snmp mac table and build a network map based on your arp table. Everything that I managed to google is usually wildly cumbersome, most often paid and generally unnecessary.

Answer 1

The main problem of such programs is to remove poppies via snmp. One manufacturer, in different firmware versions, may have different methods. And then - everything is simple, run recursively through ports-vlans. Python / pearl in hand.
On business - lantopolog is quite good. It does not show some ports in the demo version. But you can run it again - it won't show others :) It's not expensive

Answer 2

dude try it

Answer 3

Here only nmap (zenmap) comes to mind.
