Hello,

I am inheriting a network that has a Juniper EX4200 switch. No one knows the IP address of the device. How can i find it without doing a console to it?

If you can't console to it, then you will likely need some sort of IP scanner that can scan the subnet and give you an idea of what hardware is responding.

I use Total Network Inventory a lot. They have a trial out there.

Is this a flat network?   Meaning only one subnet?

I would run a IP scanner and see if it will pick up the IP and the device.

You can use angry IP scanner or softperfect network scanner.

Yes just 1 subnet.

Let me try scanning.

You can verify it's the switch by checking out the MAC address in the scanner (using angry IP)

You can search for CDP packets in 5 minutes of traffic dump on idle port using network monitor or wireshark
