CONFIGURING
CFM MAINTENANCE
ASSOCIATIONS
Use the Administration > CFM (Configure MA) pages to create and
configure the Maintenance Associations (MA) which define a unique CFM
service instance. Each MA can be identified by its parent MD, the MD’s
maintenance level, the VLAN assigned to the MA, and the set of
maintenance end points (MEPs) assigned to it.

◆ "CFM Commands" on page 1311
COMMAND USAGE
Creating a Maintenance Association
◆ Use the Configure MA – Add screen to create an MA within the selected
MD, map it to a customer service instance (S-VLAN), and set the
manner in which MIPs are created for this service instance. Then use
the MEP List to assign domain service access points (DSAPs) to this
service instance (see "Configuring Maintenance End Points" on
page 528).
◆ An MA must be defined before any associated DSAPs or remote MEPs
can be assigned (see "Configuring Remote Maintenance End Points" on
page 530).
◆ Multiple domains at the same maintenance level cannot have an MA on
the same VLAN (see "Configuring CFM Maintenance Domains" on
page 519).
◆ Before removing an MA, first remove the MEPs assigned to it (see
"Configuring Maintenance End Points" on page 528).
◆ For a detailed description of the MIP types, refer to the Command
Usage section under "Configuring CFM Maintenance Domains" on
page 519.
Configuring Detailed Settings for a Maintenance Association
◆ CCMs are multicast periodically by a MEP in order to discover other
MEPs in the same MA, and to assure connectivity to all other MEPs/MIPs
in the MA.
