Configuring CFM Maintenance Domains

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”

on page 1007) or MAs (see

“Configuring

CFM Maintenance Associations”

on page 1003) 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”

on page 1007).

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 “Default” or “Explicit,” and the MIP creation state machine is invoked (as
defined in IEEE 802.1ag). The default option allows MIPs to be created for all interconnection
