Maintenance Domains (MDs) are applicable to 802.1ag procedures. They are the parts of the

Domain is defined by a set of Domain Service Access Points (DoSAPs), each of which can
become a point of connectivity to a service instance. Up to eight MDs can be configured in a
9145EMP NID. You can display, create, delete, and modify Maintenance Domains.
