Ethernet OAM Overview
•
The MEPs are configured on edge ports within the domain for each EVC. The MIPs are configured on
relevant ports within the domain itself (interior ports).
•
The network administrator selects the relevant points within the network to determine where mainte-
nance points are needed. The maintenance point configuration defines the MD.
•
MDs are assigned an unique level number (between 0 and 7) to help identify and differentiate the MD
within the domain hierarchy. For example, different organizations, such as operators (levels 0, 1, 2),
service providers (levels 3, 4), and customers (levels 5, 6, 7), are involved in a Metro Ethernet Service.
•
Each organization can have its own Maintenance Domain, designated by the assigned level number to
specify the scope of management needed for that domain.
The following illustration shows an example of the CFM Maintenance Domain hierarchy:
