Hi Guys !
I have 2 CRS226z connected via SFP2+ portz by 10Gb working great.
I’d like to use the other SFPz (SFP1 which are SFP/SFP+z) to connect them to CRS125 switches on both sides with 1Gb, but with NO success. The CRS226z say “I am ready” but only Tx packets, nothing receive.
The CRS125z on the other sides of the fiber are invisible.
Do these ports have to be filled with same speed SFPz - 2x 1G or 2x10G - or is it possible to use it like 1G+10G?
Any advice is appreciated.
Peter
