Hi everyone,
I’m experiencing an issue with two MikroTik switches (PoE+ Switch CRS354-48P-4S+2Q+RM) connected using SFP+ modules (Ubiquiti, OM-SM-10G-D). The modules are correctly recognized by the switches, as shown in the attached screenshots.
I’ve tried various configurations including auto-negotiation, as well as disabling auto-negotiation with rate select set to low, 10Gbps or 1Gbps, and duplex mode set to on/off. However, despite these attempts, I’m still unable to establish a link between the switches.
I’m using a duplex singlemode patch cable for the connection. I’m puzzled as to why the link is not working.
Has anyone encountered a similar issue or have any ideas on how to troubleshoot this problem? Any help or suggestions would be greatly appreciated.
Thank you in advance!
