oam-bind ingress cfm md ma egress sep segment

Function

The oam-bind ingress cfm md ma egress sep segment command configures CFM to report faults to a SEP segment.

The undo oam-bind ingress cfm md ma egress sep segment command cancels the configuration.

By default, CFM is not configured to report faults to a SEP segment.

Parameter	Description	Value
ingress egress	Configures CFM to report faults to a SEP segment.	-
md md-name	Specifies the name of an MD.	The value is a string of 1 to 43 case-sensitive characters without spaces, hyphens (-), and question marks (?). NOTE: When double quotation marks are used around the string, spaces are allowed in the string.
ma ma-name	Specifies the name of an MA.	The value is a string of 1 to 43 case-sensitive characters without spaces, hyphens (-), and question marks (?). The total length of the names of the MA and MD must be within 44 characters. NOTE: When double quotation marks are used around the string, spaces are allowed in the string.
segment segment-id	Specifies the ID of a SEP segment.	The value is an integer that ranges from 1 to 1024.
interface-type interface-number	Specifies the type and number of an Ethernet interface. interface-type specifies the interface type. interface-number specifies the interface number. The Ethernet interface must have been added to the SEP segment.	-

Usage Scenario

To associate CFM with SEP, run the oam-bind ingress cfm md ma egress sep segment command.

Precautions

When a device running SEP at the access layer connects to the aggregation layer, pay attention to the following points:

When a fault occurs at the access layer, configure topology change notification so that the aggregation layer can detect the fault at the access layer. Devices in the SEP segment can update their MAC address tables and ARP tables in a timely manner.
If a fault occurs at the aggregation layer, associate SEP with Ethernet CFM on the device between the access layer and aggregation layer so that the access layer can detect the fault at the aggregation layer. Devices at the access layer can update their MAC address tables and ARP tables.

Prerequisites

This command can take effect only when the following configurations are completed:

Run the cfm enable (system view) command to enable CFM globally.
Run the cfm md command in the system view to create an MD.
Run the ma command in the MD view to create an MA.
Run the mep mep-id command in the MA view to create a MEP.
Run the remote-mep command in the MA view to create an RMEP.
Run the mep ccm-send enable command in the MA view to enable the local MEP in the MA to send CCMs.
Run the remote-mep ccm-receive enable command in the MA view to enable the MEP to receive CCMs from the RMEP in the same MA.
The interface specified in this command has been added to the SEP segment.
