The oam-bind cfm trigger if-down command configures fault message transmission between Ethernet connectivity fault management (CFM) and its bound interface.
The undo oam-bind cfm trigger if-down command cancels fault message transmission between Ethernet CFM and its bound interface.
By default, no fault messages are transmitted between Ethernet CFM and its bound interface.

Specifies the type and number of an interface. |
- |
| ingress |
Indicates the ingress transmission. |
- |
| md md-name |
Specifies the name of an MD. |
The value is a string of 1 to 43 case-sensitive characters, spaces not supported. |
Usage Scenario
On the network Ethernet CFM is deployed between the PEs. If a fault occurs on the link between the PEs, a CE needs to detect the fault. Additionally, if a fault occurs between a PE and CE, the PE needs to notify the remote PE of the fault to ensure reliable service transmission. To meet the needs, deploy fault message transmission between Ethernet CFM and its bound interface on a PE. Table 1 describes configurations for fault message transmission between Ethernet CFM and its bound interface.
Prerequisites
An MD and MA have been created.
