Find IP of the device acting as a switch

RouterOS General
1

First… Please don’t laugh :smiley: Here is the situation:

       ┌───────┐    ┌───────┐   ┌────┐
WAN ◄──┤ RB951 ├───►│ RB951 ├───► PC │
       └───────┘    └───────┘   └────┘
        Router       Switch

I need to access the RB951 that acts as the switch. I have scanned all conceivable IP ranges, but to no avail.
I do have login credentials for it, so this is not an issue. Both devices belong to me so I can do whatever I want with either.

Any ideas?

Can you use romon starting from Router-RB ?

What if you use winbox connected to that RB-switch-device and then go to tab Neighbors ? It should show the MAC address. And then you should be able to access it (provided credentials are correct).

3

I am certain that neighbours discovery and RoMon are switched off on the device.

4

But you should be able to access it using Winbox and MAC address ?
MAC address should be on a label on the bottom of the device.
Or check ARP table on Router-RB (terminal:/IP Arp print, Winbox: IP Arp-list)


EDIT: it’s not needed to quote a complete post if nobody has answered in between …

Hmm… Found the MAC address via arp cache, device does not respond. Will try different physical ports, I might have enabled service only on a specific one.
As the switch, however, it functions perfectly :slight_smile:

What is so valuable in the existing configuration of the 951 acting as a switch that prevents you from resetting it to factory defaults?

Other than that, I’m probably missing something - if you can see the MAC address in the ARP cache, you should see its IP address there too, as the very purpose of the ARP cache is to map IP addresses to MAC addresses?

That question has passed in my mind as well, yes…

Nothing too valuable. Will try to connect via IP once I get to the device and reset it if all fails.

Thanks for the hint re. ARP cache!
