A maintenance association is a set of MEPs configured with the same maintenance
association identifier and maintenance domain level. Figure 62 on page 1129 shows the
hierarchical relationships between the Ethernet bridge, maintenance domains,
maintenance associations, and MEPs.

Configuring Maintenance Association Intermediate Points in ACX Series
Maintenance Intermediate Point (MIP) provides monitoring capability of intermediate
points for services such as Layer 2 bridging, Layer 2 circuit, and Layer 2 VPN. ACX5048
and ACX5096 routers support MIPs for the Ethernet OAM 802.1ag CFM protocol. Use
the bridge-domain, interface, and mip-half-function MIP options to specify the MIP
configuration.
NOTE: ACX5048 and ACX5096 routers do not support MIP configuration
on VPLS services.
NOTE: Whenever a MIP is configured and a bridge domain is mapped to
multiple maintenance domains or maintenance associations, it is essential
that the mip-half-function value for all maintenance domains and
maintenance associations be the same.
To display MIP configurations, use the show oam ethernet connectivity-fault-management
mip (bridge-domain | instance-name | interface-name) command.
The following MIP configurations are supported in ACX5048 and ACX5096 routers:
