LINK FAULT PASS THROUGH (LFPT)
Link Fault Pass Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end user to visually detect that the Link
and its associated LEDS on the front faceplate of the module are not lit when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.
The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and EXT management.
LFPT can be enabled between any two ports. For example, if LFPT is configured
as “from” the Optics port “to” the Data port, then when a fault occurs on the
Optics port , both LEDs for those ports will extinguish. The end-user can decide
which port he wants the fault to be reported to, based on which port he wants to
be in control. LFPT allows the fault to be reported down the line through to the
link partner at the end, such as a switch or a router.
