# 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.
