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 know whether
an LSP has failed by checking the logs.
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 will
be deleted and a new BFD session will be established according to the control plane.
To configure the periodic LSP tracert function:
To do...
Enter system view
Enable LSP verification and enter
the MPLS LSPV view
Configure periodic tracert for an
LSP to the specified FEC destination

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 switch. 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.
