CRS504-4XQ with 100G-SR4

Tue Apr 11, 2023 3:32 pm

Hi,

I just received a CRS504-4XQ, but have issues getting the 100G links to work.
I moved one side of a working 100G-SR4 link between two Juniper QFX5210-32C to the CRS.
However, the link remains down on Router OS 7.8 and 7.9rc2.
I changed FEC to fec91 on the Mikrotik side as "auto" showed a disappearing SFP in /interface/ethernet/monitor qsfp28-4-1.
It is now matching FEC on the Juniper-side. While this didn't help, I switched to FEC none on both sides.
The Mikrotik-side shows link-up for about 15s just to flap again, Juniper-side stays down.

Another question is how I can get rid of the breakout interfaces, as this is 1x 100G and we do not intend to split into 4x25G or 4x10G.

Any other ideas?

Cheers,
Frank
