92 Chapter 2
?– Remote loopback Enables a loopback to be initiated from one entity to a remote
peer entity to ensure the quality of the intervening Ethernet circuit (specific tests
for delay, jitter, and so on, can also be measured).
?– MIB variable retrieval Provides a management information base (MIB), which is
a database of management variables and typically includes all performance and error
statistics maintained on an Ethernet link. The IEEE 802.3ah Ethernet OAM provides
a read-only access remote MIB (and does not allow the variables to be set).
Organization Specific Extensions The IEEE 802.3ah OAM also allows equipment
vendors to extend Ethernet OAM capabilities through organizational-specific PDUs to
support additional capabilities, such as extending OAM messages beyond one link and
monitoring other equipment performance parameters, that will contribute to offering
more robust Ethernet services.
Ethernet-Local Management Interface (E-LMI) The E-LMI, specified in the MEF
16, defines the protocol to communicate service-level information to enable the automatic
configuration of the Customer Premise Equipment (CPE). This ability allows
the Service Provider to ensure, remotely, that the CPE is set up correctly to support a
specific Ethernet service, rather than have the enterprise administrator configure it.
