Basic configuration tasks include:

Configuring Service Instance

Configuring MEP

Configuring MIP Generation Rules 

 

Based on the network design, you should configure MEPs or the rules for generating MIPs on each 

device. However, before doing this you must first configure the service instance. 

 

A service instance is indicated by an integer to represent an MA in an MD. The MD and MA define the 

level and VLAN attribute of the messages handled by the MPs in a service instance. 

Follow these steps to configure a service instance:

Enable CFD 

Required 

CFD is disabled by default.  

Configure the CFD protocol 
version 

cfd version { draft5 | 
standard } 

Optional 

By default, CFD uses the 
standard version of IEEE 
802.1ag. 

Create an MD 

cfd md md-name level 
level-value 

Required 

Not created by default 

Create an MA 

cfd ma ma-name md md-name 
vlan vlan-id 

Required 

Not created by default 

Create a service instance 

cfd service-instance 
instance-id md md-name ma 
ma-name

These configuration tasks are the foundation for other CFD configuration tasks. 

z 

The last three steps in the table above must be performed strictly in order. 

z 

The CFD protocol version used on different devices in an MD must be consistent; otherwise, the 

devices cannot exchange CFD protocol packets.
