Hello everyone!

I'm new to MikroTik configuration and have come across a problem that is unsolvable for me.

I have a 1.5Gbps static IP internet link, coming through an optical fiber.

This internet link is currently connected to a CCR2004-16G-2S+
via an SFP+ port. The link is configured correctly and the
SFP+ port is configured as:
- Auto negotiation = OFF;
- Tx Flow Control = auto;
- Tx Flow Control = auto;
- Speed = 10Gbps;
- Full Duplex = ON.

However, I need to change this link to another device, model
RB3011UiAS-RM. I use the same GBIC SFP and the same link configuration.
link configuration. The MikroTik even recognizes the fiber signal, but it is not does not receive internet.

I've already checked with my provider to see if there's any link between the link and the device's MAC, but there isn't.

Could anyone help me?

You're aware that the RB3011 has an SFP port, not an SFP+ one? You can use an SFP in an SFP+ cage, but not vice versa.
