cfm mip

Function

The cfm mip command creates a maintenance association intermediate point (MIP) on a specified interface.

The undo cfm mip command deletes a MIP from a specified 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 ranging from 0 to 7. A larger value indicates a higher level.

Usage Guidelines

Usage Scenario

You can create a MIP in a maintenance domain (MD) to enable segment-by-segment fault locating and verification for the maintenance point (MP) or link.

A MIP, residing inside the MD, does not send continuity check messages (CCMs) but can process and respond to CCMs. A MIP does not process packets with a level higher or lower than its level but forwards them as required; a MIP only processes packets with the same level as its level.

If a MIP is created and an MP performs Loopback or Linktrace, the MIP will reply with loopback messages (LBMs) or linktrace messages (LTMs) to perform segment-by-segment fault locating and verification for the MP or link in the MD.

Prerequisites

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

Example

# Create a MIP with the level set to 4.
