Default Level
1: Monitor level
Parameters
advertisement: Specifies advertisement event debugging.
all: Specifies all event debugging.
error: Specifies error event debugging.
hsb: Specifies hot standby event debugging.
main: Specifies debugging for external module related main interface event .
notification: Specifies notification event debugging.

Description
Use the debugging mpls ldp command to enable debugging for LDP.
Use the undo debugging mpls ldp command to disable debugging for LDP.
By default, debugging is disabled for LDP.
Examples
# Enable LDP advertisement event debugging by executing the debugging mpls ldp
advertisement command
Start two switches, connect the two switches, and configure MPLS and MPLS LDP for
them to establish a session between them. Enable LDP advertisement event
debugging by executing the debugging mpls ldp advertisement command on one
switch while restarting LDP on the other switch.

1.1.2 debugging mpls lfib
Syntax
debugging mpls lfib [ code | sync ]
undo debugging mpls lfib [ code | sync ]
View
User view
Default Level
2: System level
Parameters
code: Enables debugging for MPLS entry encoding and decoding.
sync: Enables debugging for MPLS entry synchronization.
Description
Use the debugging mpls lfib command to enable debugging for MPLS entry
synchronization or encoding and decoding.
Use the undo debugging mpls lfib command to disable debugging for MPLS entry
synchronization or encoding and decoding.
By default, the debugging for MPLS entry synchronization and encoding/decoding is
disabled.
Caution:
z Do not enable debugging for MPLS entry encoding and decoding when there are a
large number of entries to be sent. Otherwise, there will be large amounts of
command output information, affecting the normal operation of the system.
z The output debugging information for encoding is from the main board, and that for
decoding is from the interface board and the backup main board.

1.1.5 debugging mpls management
Syntax
debugging mpls management { agent | all | event | interface | policy | process|
tunnel }
undo debugging mpls management { agent | all | event | interface | policy |
process| tunnel }
View
User view
Default Level
2: System level
Parameters
agent: Enables MPLS Agent debugging.
all: Enables MPLS debugging.
event: Enables MPLS event debugging..
interface: Enables MPLS interface debugging.
policy: Enables debugging for the policy whereby LDP establishes LSPs.
process: Enables MPLS process debugging.
tunnel: Enables MPLS tunnel debugging.
Description
Use the debugging mpls management command to enable MPLS LSP debugging.
Use the undo debugging mpls management command to disable the debugging.
By default, MPLS debugging is disabled.
If the LSP management (LSPM) module works improperly, you can execute the
debugging mpls management command to locate the fault. However, the execution
of this command will affect system performance. Therefore, use this command with
caution.
Examples
# Enable MPLS agent debugging by executing the debugging mpls management
agent command.
Start two switches, connect the two switches, and configure MPLS and MPLS LDP for
them to establish a session between them. Enable MPLS agent debugging by
executing the debugging mpls management agent command on one switch while
executing the reset mpls ldp all command on the other.
