oam-bind ingress efm interface egress efm interface

Function

The oam-bind ingress efm interface egress efm interface command enables an EFM OAM session to report faults to another EFM OAM session.

The undo oam-bind ingress efm interface egress efm interface command disables an EFM OAM session from reporting faults to another EFM OAM session.

By default, unidirectional transmission of information about a fault from one EFM OAM session to another EFM OAM session is not configured.

Only the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI support this function.

Usage Guidelines

Usage Scenario

If EFM is deployed at both sides of a device, associate EFM modules on the device to ensure reliable service transmission.

Association between EFM and EFM is bidirectional. EFM modules notify each other of faults.

The following commands are used to associate EFM modules:

oam-bind efm interface efm interface
oam-bind ingress efm interface egress efm interface

Choose the preceding commands in different scenarios according to Table 1.

**Table 1** Association between EFM modules
Scenario	Configuration Solution 1	Configuration Solution 2
Bidirectional fault notification between EFM modules	Run the oam-bind efm interface efm interface command.	Use the following commands: Run the oam-bind ingress efm interface egress efm interface command to configure EFM for the link at one side of the device to notify EFM for the link at the other side of the device of faults. ingress efm interface interface-type interface-number specifies the EFM-capable interface on the link at one side of the device, and egress efm interface interface-type interface-number specifies the EFM-capable interface on the link at the other side of the device. Run the oam-bind ingress efm interface egress efm interface command to configure EFM for the link at one side of the device to notify EFM for the link at the other side of the device of faults. ingress efm interface interface-type interface-number specifies the EFM-capable interface on the link at one side of the device, and egress efm interface interface-type interface-number specifies the EFM-capable interface on the link at the other side of the device.
Unidirectional fault notification between EFM sessions	Choose either of the following commands based on the transmission direction: Run the oam-bind ingress efm interface egress efm interface command to configure EFM for the link at one side of the device to notify EFM for the link at the other side of the device of faults. ingress efm interface interface-type interface-number specifies the EFM-capable interface on the link at one side of the device, and egress efm interface interface-type interface-number specifies the EFM-capable interface on the link at the other side of the device. Run the oam-bind ingress efm interface egress efm interface command to configure EFM for the link at one side of the device to notify EFM for the link at the other side of the device of faults. ingress efm interface interface-type interface-number specifies the EFM-capable interface on the link at one side of the device, and egress efm interface interface-type interface-number specifies the EFM-capable interface on the link at the other side of the device.	None

Precautions

Ingress EFM OAM reports faults to egress EFM OAM.
