Link Fault Pass-Through (Lfpt); Using Far End Fault, And Fiberalert - IMC Networks iMcV-LIM Operation Manual

Link Fault Pass-Through (LFPT)

Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote iMcV-LIM modules. LFPT is enabled by
turning on both FX and TX LinkLoss on both modules. This feature allows either end
of the conversion to detect a link fault occurring at the other end of the media
conversion chain.
Regardless if there is a break in segment 1, 2 or 3, the link will drop on the switches
at both ends. The link fault is passed through the media conversion and is observed
at each end. It acts just like it would if the devices were directly connected.
