i have to mikrotik
one 260gsp
cloud core ccr-1036

i want to link both using the SFP and it does not work.

i tried both as switch , so i reset everything and it is by default.
now the router it is acting like a bridge.

so i can ping everything PC using ethernet but i cannot using the SFP.

i have read i have to set it up one SFP as master and other as slave but i cannot find much info about that..

thank you in advance

same here ,
