Configuring periodic LSP tracert
The periodic LSP tracert function is for locating faults of an LSP periodically. It detects the consistency of
the forwarding plane and control plane and records detection results into logs. You can check the logs
to know whether an LSP has failed.
If you configure BFD as well as periodic tracert for an LSP, once the periodic LSP tracert function detects
an LSP fault or inconsistency of the forwarding plane and control plane, the BFD session for the LSP is
deleted and a new BFD session is established according to the control plane.

Enabling MPLS trap
With the MPLS trap function enabled, trap packets of the notifications level are generated to report
critical MPLS events. Such trap packets are sent to the information center of the device. Whether and
where the packets are output depend on the configurations of the information center. For information on
how to configure the information center, see Network Management and Monitoring Configuration
Guide.
