OAM Client

The OAM client establishes and manages Ethernet OAM on a link. The OAM client
also enables and configures the OAM sublayer. During the OAM discovery stage, the
OAM client monitors OAM PDUs received from the remote peer and enables OAM
functionality on the link, depending on the local and remote states, and configuration
settings. Outside of the discovery stage, the OAM client manages the rules of response
to OAM PDUs and the OAM remote loopback mode.

OAM Sublayer

The OAM sublayer presents two standard IEEE 802.3 MAC service interfaces: one
pointed toward the superior sublayers, which include the MAC client (or link
aggregation), and the other interface pointed toward the subordinate MAC control
sublayer. The OAM sublayer provides a dedicated interface for transmission of OAM
control information and OAM PDUs to and from a client.
