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.
Configuring 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:

z 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.
Configuring MEP
MEPs are functional entities in a service instance. CFD is implemented through operations on MEPs,
which provides such functions as CC, LB, LT and gives prompts on error CCMs and cross connections.
As a MEP is configured on a service instance, the MD level and VLAN attribute of the service instance
become the attribute of the MEP.
