display isis ldp-sync interface

Function

The display isis ldp-sync interface command displays information about LDP and IS-IS synchronization on an interface.

Format

display isis [ process-id | vpn-instance vpn-instance-name ] ldp-sync interface

Parameters

Parameter	Description	Value
process-id	Specifies the IS-IS process ID.	An integer ranging from 1 to 65535
vpn-instance vpn-instance-name	Specifies the VPN instance name.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

For all the interfaces that are enabled with LDP and IS-IS synchronization, run the display isis ldp-sync interface command to view information about LDP and IS-IS synchronization.

Example

# Display information about LDP and IS-IS synchronization on an interface.

<sysname> display isis ldp-sync interface

                   Ldp Sync interface information for ISIS(1)

**Table 1** Description of the **display isis ldp-sync interface** command output
Item	Description
Interface	Interface connected to neighbors
HoldDownTimer	Interval during which the interface must wait to create an LDP session without creating an IS-IS neighbor relationship. The default interval is 10 seconds. This interval can be configured using the isis timer ldp-sync hold-down command.
HoldMaxCostTimer	Interval at which IS-IS advertises the maximum metric value in Link State PDUs (LSPs) sent by the local device. The default interval is 10 seconds. This interval can be configured using the isis timer ldp-sync hold-max-cost command. NOTE: If the value of this field is infinite, IS-IS keeps advertising the maximum metric value in LSPs sent by the local device before the LDP session is reestablished.
LDP State	Status of an LDP session: Up Down
Sync State	Status of synchronization between LDP and IS-IS: Sync-Achieved: The creation of an LDP session and establishment of the IS-IS neighbor relationship are synchronized. HoldDown: The state in which the interface waits to create an LDP session without creating the IS-IS neighbor relationship. HoldMaxCost: The state in which IS-IS advertises the maximum metric in LSPs sent by the local device. Init: The initial state.
