Got a CRS125-24G-15-2HnD-IN Could Router Switch.
All I really want to use it as right now is as an, let's say, in-house switch, or just a switch. No routing will needed between networks. Another server in the office works as DHCP, so I just need this CRS125 to really be a switch/hub. So far, I've been able to kind of get it there, but I'm obviously not configuring it correctly.
And because I'm so limiting the possibilities of this device, I think I may be the first person to do this. Can someone get me routed (ha!) toward the right answer to get the device functioning. I'd really appreciate it.
Thanks!

Pretty sure it works out of the box as a switch, at least on ports 2-24. Port 1 may be a WAN port.

You can connect with WinBox, do a system/reset configuration and check 'No default configuration'.

After it reset's connect via WinBox again via Mac address and set the master port for Ethernet interfaces 2-24 and sfp to Ether1. (May disconnect temporarily)

If you want a management ip for WinBox, Webfig, etc. you can assign one to the master port Ether1.
