Non-Isolating Errors are “soft error” conditions that could have been
caused by any station on the ring. Their fault domain cannot be detected.
Lost Frame Errors
This field displays the total number of Lost Frame Errors. These errors
occur when the adapter fails to receive the end of the frame it has just
transmitted. The frame was lost somewhere on the ring but there is no way
to pinpoint where. This can be caused by stations entering or leaving the
ring.
