MIKROTIK SFP PROBLEM

Fri Sep 07, 2018 9:55 am

I have a switch configuration connected to a CCR1009 through the S + DA0001 fiber cable from Mikrotik. I have vlans truncated by said SFP, when I do it, with version 1.5.x every 30 seconds traffic stops flowing and all the vlans fall, after a few seconds they are restored. This does not happen if I have version 1.4.9 installed. Is there any information about it?

Did you try setting the SFP Speed/Duplex to 1G on both sides and or Auto on both sides?

Some SFP modules like 1G some like AUTO but needs to be the same on both sides of link.

Could you post up the follow TABs

Ports / LAG / STP / Device/Status

I would suspect STP issue, broadcast strom protection issue, or an other similar option. Any log ?
