cfm mp-address-model

Function

The cfm mp-address-model command configures a maintenance point (MP) address model.

The undo cfm mp-address-model command restores the default MP address model.

By default, the MP address model is bridge.

Format

cfm mp-address-model { bridge | individual }

undo cfm mp-address-model

Parameters

Parameter	Description	Value
bridge	Indicates the shared MP address model. All maintenance association end points (MEPs) and maintenance association intermediate points (MIPs) on a device share a bridge MAC address.	-
individual	Indicates the individual MP address model. All MEPs and MIPs on a device use their interface MAC addresses.	-

Parameter

Description

Value

bridge

Indicates the shared MP address model. All maintenance association end points (MEPs) and maintenance association intermediate points (MIPs) on a device share a bridge MAC address.

individual

Indicates the individual MP address model. All MEPs and MIPs on a device use their interface MAC addresses.

Usage Guidelines

Usage Scenario

IEEE Standard 802.1ag-2007 defines the following MP address models:

Shared MP address model: All MEPs and MIPs on a device share a bridge MAC address. This model saves MAC entry storing space.
Individual MP address model: All MEPs and MIPs on a device use their interface MAC addresses. This model facilitates fault locating.
To configure an MP address model, run the cfm mp-address-model command.

Configuration Impact

If the shared MP address model is configured, MPs on a device use the same bridge MAC address as their own MAC addresses.
If the individual MP address model is configured, MPs on a device use interface MAC addresses as their own MAC addresses. (If the interfaces are Layer 2 interfaces switched from Layer 3 interfaces using the portswitch command, the MAC addresses of Layer 3 interfaces are used.)

Precautions

If connectivity fault management (CFM) has been enabled, run the undo cfm enable command to disable it before running the cfm mp-address-model command.

The CFM MAC address mode was modified. cfm mp-address-model command deletes all CFM configurations on a device.
