Lpt; Bearer Mode - Huawei OptiX OSN 550 Configuration Manual

7 List of Parameters

7.90 LPT

Description
The LPT parameter specifies whether the link state pass through (LPT) function is enabled. The
LPT is a technology developed by Huawei to increase the speed of the link state response.
Through the LPT protocol, the faults on the service access point and in the intermediate network
can be detected and reported.
Impact on the System
When the LPT function is enabled, the faults on the service access point and in the intermediate
network can be detected and reported. For example, the service access point can be informed of
the fault in the intermediate network and thus can handle the fault accordingly (switch the service
to the backup link). When the LPT function is disabled, the link fault in the intermediate network
is not reported to the service access point.
