Use the Administration > CFM (Configure MD) pages to create and
configure a Maintenance Domain (MD) which defines a portion of the
network for which connectivity faults can be managed. Domain access
points are set up on the boundary of a domain to provide end-to-end
connectivity fault detection, analysis, and recovery. Domains can be
configured in a hierarchy to provide management access to the same basic
network resources for different user levels.

Configuring General Settings
• Where domains are nested, an upper-level hierarchical domain must
have a higher maintenance level than the ones it encompasses. The
higher to lower level domain types commonly include entities such as
customer, service provider, and operator.
•
More than one domain can be configured at the same maintenance
level, but a single domain can only be configured with one maintenance
level.
•
If MEPs (see Configuring Maintenance End Points) or MAs (see
Configuring CFM Maintenance Associations) are configured for a
domain, they must first be removed before you can remove the
domain.
Maintenance domains are designed to provide a transparent method of
verifying and resolving connectivity problems for end-to-end
connections. By default, these connections run between the domain
service access points (DSAPs) within each MA defined for a domain,
and are manually configured (see Configuring Maintenance End Points).
In contrast, MIPs are interconnection points that make up all possible
paths between the DSAPs within an MA. MIPs are automatically
generated by the CFM protocol when the MIP Creation Type is set to
