MPLS Display and Debug

685

Displaying MPLS-enabled interfaces

After accomplishing the configuration tasks mentioned earlier, you can execute
the

display

command in any view, to view the information related to the

MPLS-enabled interface and thus to evaluate the effect of the configurations.

Displaying LSP

Please execute the following commands in any view to display the information
related to MPLS LSP.

Debugging MPLS

You may execute the

debugging

command in user view to debug the information

concerning all interfaces with MPLS function enabled.

Because enabling debugging may affect the router performance, you are
recommended not to use this command unless necessary. Execute the

undo

form

of this command to disable any individual debugging.

There is a predefined hotkey that executes the undo debugging all command. As
debug messages have the potential to overwhelm Telnet and/or console output.
The undo debugging all hotkey provides a more efficient way to restore Telnet
and/or Console output rather than trying to type individual undo debugging
commands.

Trapping MPLS

This command is used to enable the trap function of MPLS during an LSP/LDP
setup process.
