1.5.3 Enabling the Trap Function of LSP

By configuring the trap function on an LSP, you can notify the NMS of the changes of the LSP
status.
Context
Run the following commands in the system view to notify the Network Management System
(NMS) of the LSP status change.
By default, the trap function is disabled during the setup of the LDP LSP.
Procedure
Step 1 Run the snmp-agent trap enable feature-name mpls_lspm trap-name { mplsxcup |
mplsxcdown } command to enable the trap function for the LDP LSP and enable the debugging
of excessive LSP Up events or LSP Down events.
Step 2 (Optional) Run the snmp-agent trap suppress feature-name lsp trap-name { mplsxcup |
mplsxcdown } trap-interval trap-interval [ max-trap-number max-trap-number ] command
to configure the interval for suppressing the display of excessive LSP traps.

1.5.4 Debugging MPLS

You can enable the debugging of a certain module in the user view to view information generated
by a device. The debugging information indicates information about the data packets received
or sent by the debugged module.
Context
Debugging affects the performance of the system. After debugging, execute the undo debugging
all command to disable it immediately.
When an MPLS fault occurs, run the following debugging commands in the user view to locate
the fault.

If draft6 is specified, the command is implemented according to draft-ietf-mpls-lsp-
ping-06. By default, the command is implemented according to RFC 4379.
Run:
tracert lsp [ [ -a source-ip | -exp exp-value | -h ttl-value | -r reply-mode |
*
-t time-out ] ] ip destination-address mask-length [ ip-address ] [ nexthop
nexthop-address | draft6 ]
MPLS tracert is performed.
If draft6 is specified, the command is implemented according to draft-ietf-mpls-lsp-
ping-06. By default, the command is implemented according to RFC 4379.
