Hardware: CRS309-1G-8S+IN
RouterOS: 7.12.1, 7.13rc
I guess this part of 7.12 changelog broke something:
Notice - SFP/QSFP functionality has been refactored for consistent behavior and better scalability. Now, compliance with SFP/SFP+/QSFP MSA standard is mandatory. This may cause issues with SFP/QSFP modules that are not fully compliant. All current MikroTik modules abide this standard.
I’m getting from time to time link loss on the official Mikrotik S+RJ10. The SFP is actively cooled and does not exceed 80 degrees. The problems did not occur before 7.12 release. Downgrading to 7.11.3 seems to fix the issue.
