OAM (Operations, Administration, and Maintenance) can provide the remote equipment management function to the operator in the telecom network. When the network fails, OAM can generate the alarm message to help the operator find out the network failure and make sure the network in which network MP (maintenance point) fails. In this paper, we investigate the Ethernet OAM standards that include IEEE 802.1ag, ITU-T Y.1731 and IEEE 802.3ah. Moreover, we introduce the CFM (Connectivity Fault Management) developed status in the AGG-E (Access Aggregation Edge Network), AGG-C (Access Aggregation Center Network) and GPON (Gigabit-capable Passive Optical Network) equipments, and design the MP allocation scheme in the GPON and AGG-C to satisfy different users' management requirements. Finally, according to OAM capabilities test technologies to help the Ethernet OAM adopted in the telecom network.
