The SFP+ connections on either the Miktrotik CSS326 and CRS305 aren't functioning properly.
The SFP+ connections on either the Miktrotik CSS326 and CRS305 aren't functioning properly.
I'm dealing with a Miktrotik CSS326 and a CRS305 connected via a 10gb fiber link. It's been running smoothly since January, but starting yesterday the connection dropped. I can still access each switch using devices on their sides, but data transfer between switches only works temporarily by switching SFP+ ports—usually for just a couple of minutes. I've spent about seven hours trying to resolve this issue.
Are there more transcivers to try? It looks like they're running low.
Essentially every electronic component has a chance to malfunction unexpectedly, which isn't too surprising. Consider acquiring another set of single-mode converters.
Verify temperatures to ensure it isn’t overheating. Probably best to use the models available, though they might not connect with SM cable.
Have you explored switching between RouterOS and SwOS to rule out a software problem? Also, consider testing with different optical connections and patch updates.
