display mpls ldp interface

Function

The display mpls ldp interface command displays information about MPLS LDP-enabled interfaces.

Format

display mpls ldp interface vpn-instance vpn-instance-name

display mpls ldp interface vpn-instance vpn-instance-name { interface-type interface-number | interface-name | verbose }

display mpls ldp interface [ all ]

display mpls ldp interface { interface-type interface-number | interface-name | verbose }

display mpls ldp interface all verbose

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Displays events that LDP adjacencies in a specified VPN instance go Down.	The value is a string of 1 to 31 case-sensitive characters. It cannot contain spaces. The VPN instance name cannot be <b>_public_</b>. However, the character string can contain spaces if it is enclosed with double quotation marks (").
interface-type	Specifies the type of an interface.	-
interface-number	Specifies the number of an interface.	-
interface-name	Specifies the name of an interface. If this parameter is specified, the configurations of a specified LDP-enabled interface are displayed.	-
verbose	Displays detailed information about LDP-enabled interfaces.	-
all	Displays information about all LDP-enabled interfaces.	-

Usage Guidelines

Usage Scenario

After completing basic MPLS LDP configurations, run the display mpls ldp interface command to view configurations of LDP-enabled interfaces and part of real-time information, such as the number of sent and received Hello messages.

Prerequisites

MPLS and MPLS LDP have been enabled globally.

Configuration Impact

After the display mpls ldp interface command is run, information about the LDP-enabled interface is displayed.

Example

The actual command output varies according to the device. The command output here is only an example.
