Usage Guidelines

Usage Scenario

When there are a great number of BFD sessions, you can view information about BFD sessions with a specified type, name, or bound peer address.

Prerequisites

BFD has been globally enabled using the bfd command in the system view.

Precautions

If a static BFD session with automatically negotiated discriminators and a dynamic BFD session have the same configurations, you can view that the shared BFD session belongs to both the static session and the dynamic session in terms of the BFD session type.

Example

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

Table 1 Description of the display bfd configuration verbose command output
Item Description
BFD Session Configuration Name

Name of the session.

BFD Bind Type

Binding type of the BFD session:

  • Peer Ip Address: The BFD session detects a multi-hop IP link.
  • For the single-hop IP link to be detected, the interface and the bound local interface are displayed.
  • PW: The BFD session detects a PW.
  • VSI_PW: The BFD session detects a VSI PW.
  • SR_BE_TUNNEL: The BFD session detects an SR-MPLS BE tunnel.
  • TE_TUNNEL: The BFD session detects a TE tunnel.
  • TE_LSP: The BFD session detects an LSP that is bound to a TE tunnel.
  • LDP_LSP: The BFD session detects an LDP LSP.
  • SID_LIST: The BFD session detects the SR TE Policy.
Session Description

Description of the BFD session.

Local Discriminator

Local discriminator of the BFD session.

Local Detect Multi

Local detection multiplier.

Remote Discriminator

Remote discriminator of the BFD session.

Bind Session Type

Establishment type of the BFD session:

  • Static: A BFD session is established through static configuration.
  • Dynamic: The establishment of a BFD session is triggered dynamically.
  • Static_Auto: A static BFD session is established through automatically negotiated discriminators.
  • Entire_Dynamic: The establishment of a BFD session is triggered dynamically, after the egress of an LSP is enabled with the function of passively creating a BFD session.
Bind Peer IP Address

Remote IP address of the BFD session.

Bind Interface

Outbound interface to which the BFD session is bound.

Bind Application

Application to which the BFD session is bound:

  • No Application Bind is displayed if no application is bound to the BFD session.
  • A specific application name is displayed if the application is bound to the BFD session. For example, if an interface is bound to the BFD session, IFNET is displayed.
Track Interface

Specifies an interface monitored by a BFD session.

TOS-EXP

Priority of BFD packets.

Min Tx Interval (ms)

Configured minimum interval between sending BFD packets.

Min Rx Interval (ms)

Configured minimum interval between receiving BFD packets.

WTR Interval (ms)

WTR time of the BFD session.

Process PST

Flag of processing the PST:

  • Enable: permits the BFD session to modify the PST.
  • Disable: prohibits the BFD session from modifying the PST.

If the process-pst command has been configured, the field is displayed as Enable; otherwise, the field is displayed as Disable.

Proc Interface Status

Status of the association between the status of a BFD session and an interface:

  • Enable: enables the association between the status of the BFD session and the interface.
  • Disable: disables the association between the status of the BFD session and the interface.

If the process-interface-status command has been configured, the field is displayed as Enable; otherwise, the field is displayed as Disable.

Total Commit/Uncommit CFG Number

Total number of committed and uncommitted BFD configurations.

To commit BFD configurations, run the commit command in the BFD session view.
