We've got a ton of Mikrotiks out there. On SFP's we're mostly using the
cheap Fiberstore stuff.
A handful of times we've had to trace down a packet loss issue on a
fiber connection, and in any of the cases I've touched all of the
Mikrotik error counters were zero. We end up troubleshooting by
swapping parts one at a time until the problem goes away, and this
offends my sensibilities.
So when something is clearly wrong, why aren't errors reported? Is it:
1) Mikrotik interfaces never report errors to begin with?
2) My cheapo SFP's don't report an error to the host switch/router?
3) An error at the SFP is invisible to the host switch/router?
......and I'm not talking about optical problems because those are
detectable with an OTDR pretty much 100% of the time. Talking
specifically about issues with switches and SFP's.
