software to find computers connected to switches

[maandim]

We have two swicthes one belonging to 3com and one belongs to Dlink in our office. Some computers are connected to 3Com switch and some of them are connected to Dlink. Is there any tool in the market, which will help to find out which computer is connected to which switch board ?

netview maybe

but i think you have to pay for it

How would you want to see this info, or what is important?

Do you want to know which switch (3Com or Dlink), the port on that switch, the IP of the host, the name of the host (Netbios, or FQDN), MAC address, etc..

First, at a minimum each of the switches would have to be manageable. Meaning they would need to be able to support having an IP address, and probably SNMP polling so that you can login to the swtich and poll SNMP info.

If that was doable by each switch then some simple little scripts could be written to collect the rest of the info. You would likely have to create your own coorelation from MAC -> IP -> to hostname

There may also me some decent freeware products that can help with this, depending on the OS you are using.

Netman is right, you would need manable switches. There are tools that will map computers to managed switch ports. Centennial Asset Managment is one that does this, but that is probably overkill. You should be able to write telnet scripts and/or PHP driven website that uses SNMP queries (we have an in house VLAN manager that works this way)
