Hi, I got my switch uplinked via 10G DAC Active (DAC fs.com https://www.fs.com/de-en/products/74625 ... &id=147869 ) on the switch I keep getting these error Rx MAC Errors, Rx FCS Errors and Tx Pauses, switch firmware v 2.12.
Do SWOS have SFP+ bugs?
thanks,
regards

The RB4011 SFP+ port is a little weird. We have had much better luck using a couple of these and a patch cable https://www.fs.com/products/11556.html? ... &id=162909
Re: css326 and rb4011 getting errors with 10G SFP+ uplink
The problem looks to be solved by cleaning the DAC's SFP modules.

Did you clean the connector or the optical side? And how?
Re: css326 and rb4011 getting errors with 10G SFP+ uplink
I cleaned the part that goes into the switch, not a great way to clean but I used a cotton cloth, will see if errors will show up, usually I get errors right away, but will see

Re: css326 and rb4011 getting errors with 10G SFP+ uplink
There were problems with using the SFP+ port on the 4011 with DAC cables in the past. The issue has been fixed in RouterOS, but we still use optical connections on 4011s and have no issues.
I would change to optical and see if the FCS errors continue.

update.
The problem was the FS.com DAC, I got the XS+DA0001 DAC from Mikrotik and it works great.

About this particular cable: can someone explain to me why this one works in the 4011, while others (sfp+) do not?
