How to get a report of all mac addresses on another subnet?

  • 772

We have an MPLS consisting of two branches: Location1 and Location2.

I am using the Softperfect netscan to report all ip addresses and mac addresses of devices on Location1 where my workstation is located (subnet1).

However, I want to have the same report on my workstation (at location1) for all devices in Location2 which is on a separate subnet which I administer.

Now I know I could get that report via remote-desktop connection to a machine there and running netscan.

How can I get the report directly?

I would like a similar report:

  • All connected devices
  • device name
  • ip addresses
  • mac addresses

Somebody told me about using SNMP?

  1. You can't (unless you have two subnets on the same network segment). You have to do this via a machine (or the router) in the Location2 network. Because broadcasts don't cross router boundries.

    We went about setting up our MPLS in a different manner. Now when I run the netscan, it does indeed, give me a report of the MAC addresses of devices on the other subnet.

    In an MPLS, if properly configured, the two subnets should work together as if they were a single network - file-sharing works normally, computers can discover each other on the other subnet, etc.

    I am using the SoftPerfect Network Scanner, and enter the range of my other subnet, and it is ppulated normally.

    I think the solution also has to do with having a working WINS server established.
