LFPT Function
A media converter performs frame forwarding between two port segments. The port segments may be different
media types, a copper cable, a multi-mode fiber cable or single mode fiber cable. They also may be in different
speeds.
The Link Fault Pass Through (LFPT) function is an import optional function to a media converter device. As it
is enabled the media converter detects a link fault on one port segment, it will force the other port segment link
down. It looks as though a link fault status is passed from one port segment to the other.
