cfm mip

Function

The cfm mip level command creates a MIP on an interface.

The undo cfm mip command deletes a MIP on an interface.

By default, no MIP is created.

Format

cfm mip level level-value

undo cfm mip

Parameters

Parameter	Description	Value
level level-value	Specifies the level of a MIP.	The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority.

Views

Ethernet interface view, GE interface view, XGE interface view, 25GE interface view, 40GE interface view, 100GE interface view, MultiGE interface view, Eth-Trunk interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

To identify and locate faults on an MP or a link in an MD, create a MIP in the MD.

A MIP is located inside the MD. It can process and respond to CCMs, but cannot send CCMs. When a MIP receives a packet carrying a level higher than its own, the MIP does not process the packet and forwards it along the original path. A MIP forwards only the packet in which the level is lower than or equal to its own.

If a MIP is created and an MP performs LB or LT, the MIP will reply with LBMs or LTMs to identify and locate faults for the MP or link in the MD.

A MIP can be created manually or automatically:

The cfm mip level level-value command can be used to manually create a MIP. This configuration is simple, but it is difficult to manage many MIPs and configuration errors may occur.
The mip create-type (MD view) command can be used to define the rule for creating a MIP and enable the device to automatically create a MIP based on the rule. Configuring creation rules is complex, but properly configured rules ensure correct MIP settings.

Prerequisites

CFM has been enabled globally using the cfm enable (system view) command.

Precautions

Only IEEE Std 802.1ag-2007 supports the manual MIP configuration.
