CCR2004 no connection via Switch

Sun Mar 19, 2023 4:45 pm

Dear all

I am not very familiar with MikroTik, so I don't know if the information here is enough for debugging. If not, I will be happy to provide the necessary information.

I have a CCR2004-1G-12S+2XS which I want to put WAN-side direct to the Internet. For this I have another router, on which a static IPv4 network is configured.

If I connect the WAN interface (sfp28-1) directly to the other router using DAC cable, the connection works.

If I use the same cable and connect the MikroTik router via a switch, it does not receive a link.

The ports on the switch are all in the same VLAN. Other firewalls are connected to the switch, which works without any problems.

Here is also my config file:
# mar/19/2023 13:21:47 by RouterOS 7.8
# software id = 88LN-20R4
#
# model = CCR2004-1G-12S+2XS
# serial number = XXX

/tool mac-server

Am I missing something?

Thank you and best regards

I found it out. I had to change the FEC mode:
