Anyone tried if a QSFP+ breakout DAC can be used on CRS326 to join 4 Mikrotik SFP+ ports to a QSFP+ host, as 3rd (or 4th) QSFP+ connection, on top of the builtin 2 QSFP+ ports?

Upgraded my CRS317 to 2.10, and 1000Base-T sfp modules' functionality survived this, with the previous Disable/Enable done once on previous 2.9 version. Also verified 1000Base-T sfp functionality over power outage. So, at least for me, it looks like 1000Base-T sfp problems with working short-distanc...

Hi os62, I'm sorry for the trouble downgrading the SwOS firmware in your switch. Maybe the file you used was not the right one for your device? ...I don't know... In every case my switch is the "CSS326-24G-2S+" and it is different from your model (CRS317-1G-16S+). Perhaps the behavior cha...

I tried mr. D'Alessio's suggestion of downgrading to 2.8.
That, instead of improving matters, started to flap all ports on the switch.
So back to 2.9, and reboot-loss of 1000Base-T sfp modules on all power outages and reboots. Unfortunately.

I sure do hope this'll be fixed.

Would the community be able to recommend proven "speedy" WLAN client cards? In my case, I've got a hAP ac, and client machines with miniPCIe "half" slots; I've got very good performance with AC-8265 (M.2 card from Intel); however I'd really like the same (or better :lol: ) perfor...

Dear Sirs, I run a CRS317-1G-16S+ with SwOS 2.9. It's a great switch, however: Getting 1Gbase-T sfp modules to recognize link up is a pain. At every reboot, links on such sfp modules are dropped and stay down. The only way to get links back up again, that I know of, is to configure them no No Autone...
