undo debugging mpls ldp remote-peer [ remote-peer-name ]

View

User view

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.

Command Manual – MPLS Basics

H3C S9500 Series Routing Switches Chapter 1 MPLS Basics Configuration Commands

pdu: Specifies PDU packet event debugging.

session: Specifies session event debugging.

socket: Specifies socket event debugging.

timer: Specifies timer event debugging.

interface-type interface-number: Specifies an LDP-enabled interface by its type and

number.

remote-peer remote-peer-name: Specifies a remote peer name.

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.
