oam-bind cfm md ma bfd-session

Function

The oam-bind cfm md ma bfd-session command enables bidirectional transmission of fault messages between Ethernet CFM and Bidirectional Forwarding Detection (BFD).

The undo oam-bind cfm md ma bfd-session command disables bidirectional transmission of fault messages between Ethernet CFM and BFD.

By default, bidirectional transmission of fault messages between Ethernet CFM and BFD is disabled.

Format

oam-bind cfm md md-name ma ma-name bfd-session bfd-session-id

undo oam-bind cfm md md-name ma ma-name bfd-session bfd-session-id

Parameters

Parameter	Description	Value
md-name	Specifies the name of an MD.	The value is a string of 1 to 43 case-sensitive characters. Question marks (?), hyphens (-) are not supported.
ma-name	Specifies the name of an MA.	The value is a string of 1 to 43 case-sensitive characters. Question marks (?), hyphens (-) are not supported. The total length of MA and MD names must be no greater than 44 characters.
bfd-session-id	Specifies the ID of a BFD session.	The value is an integer ranging from 1 to 16384.

Usage Guidelines

Usage Scenario

If CFM and BFD are configured on two sides of a device, the oam-bind cfm md ma bfd-session command can be used to associate the CFM module with the BFD module to enable bidirectional transmission of fault messages between the two modules.

The association functions on a bidirectional link as follows:If the CFM module detects a fault, it notifies the BFD module on the remote end of the fault.If the BFD module detects a fault, it notifies the CFM module on the remote end of the fault.

The following commands are used when the CFM module is associated with the BFD module:

oam-bind cfm md ma bfd-session
oam-bind ingress cfm md ma egress bfd-session
oam-bind ingress bfd-session egress cfm md ma

Prerequisites

BFD and CFM have been configured.
