oam-bind ingress bfd-session egress efm interface

Function

The oam-bind ingress bfd-session egress efm interface command configures BFD to send fault messages to EFM.

The undo oam-bind ingress bfd-session egress efm interface command disables BFD from sending fault messages to EFM.

By default, BFD does not send fault messages to EFM.

Format

oam-bind ingress bfd-session bfd-session-id egress efm interface { interface-type interface-number | interface-name }

undo oam-bind ingress bfd-session bfd-session-id egress efm interface { interface-type interface-number | interface-name }

Parameters

Parameter	Description	Value
bfd-session-id	Specifies the ID of a BFD session.	The value is an integer ranging from 1 to 16384.
interface-type	Specifies the type of an Ethernet interface.	-
interface-number	Specifies the number of an Ethernet interface.	-

Usage Guidelines

Usage Scenario

If EFM OAM is deployed on one side and BFD is deployed on another side of a device, association between EFM OAM and BFD can be configured on the device. This allows EFM OAM and BFD to notify each other of faults and ensures reliable service transmission.

Association between EFM OAM and BFD is bidirectional. The details are as follows:

If EFM OAM detects a link fault, it will notify BFD of the fault.
If BFD detects a link fault, it will notify EFM OAM of the fault.

Prerequisites

EFM has been globally enabled using the efm enable command in the system view.
EFM has been enabled using the efm enable command in the interface view.
BFD has been enabled.

Precautions

Only the following types of BFD sessions support association between EFM and BFD:

Static BFD for LSP (LDP, TE, TE-LSP, static-LSP, and VLL PW) sessions (a PST is required)
BFD for IP sessions (no PST is required)

Example

# Configure BFD to send fault messages to EFM through GE 0/1/1.
