Are Those Level 4 Plates? (I wish, Nerd Bable)

Sunday was supposed to be the day I migrated a couple of machines. I have a new physical device which is described as a Level 2 switch with SFP+ ports.

The idea is to replace my small mixed routers, 2 SFP+ ports plus some RJ45 ports with either a L2 SFP+ only switch or an L3 SFP+ only routers. This allows me to move some servers around and to increase the bandwidth from nodes to the backbone.

The switch arrived with a nice little instruction manual which claims I can find a web interface at 192.168.2.1 while the website claims there is no management interface.

Plugging it into an Ethernet port with an Ethernet SFP module gives me nothing on 192.168.2.1 and nothing on 192.168.2.x/24 but for my machine. It looks like it is unmanaged.

This means, it should be a simple plug in replacement for my tiny switch, giving an upgraded data path to the backbone.

It didn’t work.

So now I have to do some more testing. I’ll figure this out, one way or another, but it is another bottleneck in my path to full conversion to fiber from copper.
