Functional Notes
This command not only creates and enables the MD, it also enters the MD Configuration mode. From the
MD Configuration mode, maintenance associations (MAs) and maintenance endpoints (MEPs) can be
configured. For more information on configuring MAs and MEPs, refer to the
Command Set on page
any MAs and MEPs defined with the domain.
The domain name serves two purposes. One is to provide a text label used in the device configuration to
identify a particular domain, the other is to construct an MAID. The MAID is included in CFM continuity
check messages (CCMs), and identifies the MA to which the transmitting MEP belongs. The MAID also
allows MEPs receiving CCMs to detect CFM error conditions.
Because each MEP supported on an AOS device port or interface must be at a different MD level, each
MEP on a particular port or interface will have to be configured on a separate MD.
For more information about Ethernet OAM CFM and its operation on AOS products, refer to the Ethernet
