From the v6.1 VSP 7200 document, NN47227-301_11_03_InstallingTransceiversOpticalComponents_VOSS.pdf :
If you use 1 Gbps fiber SFP transceivers, auto-negotiation is always disabled so the remote end
must also have auto-negotiation disabled. Otherwise this is not a supported configuration with VSP 7254XSQ.
Am I concerned about a problem which doesn't exist?
My question is:
Since Remote Fault Indication is part of AutoNegotiation, and therefore NOT available when using 1 Gbps fiber SFP transceivers, what is the Best Practice for detecting fiber faults when connecting to various remote switches?
My guess is:
VLACP can accomplish fault detection when connecting between ERS and VSP models.
what about EXOS, EOS, Cisco, Adtran, etc?
