Link fault pass through
When link fault pass through function is enabled, link status on TX port will inform the FX port of the
same device and vice versa. From the link fault pass through procedure illustrates in the figure below, if
link fail happens on IP113A LF’s TX port (1), the local FX port sends non-idle pattern to notice the remote
FX port (2). The remote FX port then forces its TX port to link failed after receiving the non-idle pattern
(4). In other words, this mechanism will alert the link fault status of local TX port to the remote converter’s
TX port, and the link status of the remote TX port will become off. Link status LED will also be off for both
IP113A LF and its link partner.
