Connection between RB3011UiAS-RM & CSS326-24G-2S+RM via SFP

Fri Aug 23, 2019 2:49 pm

Hello,

I am trying to connecte a Mikrotik RB3011UiAS-RM router with Mikrotik CSS326-24G-2S+RM switch using a Mikrotik S-DA0001 SFP cable.
And when I plug in the cable in the devices nothing happens. No LEDs light up nothing. In the management interface the port is also shown as not connected.
I tried with several different cable of the same mode, no change. When I connect to such swiches with this cable the connection is established and the ports are shown as connected in the Web GUI.
When I connect the router with another device using such cable the connection is exstablished also. => the port on the router is not dead.

What might be the reason that this particular router connect connect to this particular switch using this particular cable?

I think you need to turn off auto negotiation on the CSS and force it to 1GB.
