Ethernet OAM according to 802.3ah is used by ISPs to monitor an Ethernet-based last mile, for example with FTTH or VDSL2 connections.
OAM packets (OAM Protocol Data Units or OAMPDUs) are regularly transmitted from the active side, which is usually the ISP side. The passive side, which is usually the CPE side, responds to these OAMPDUs. This is used to monitor the availability of the remote site. This procedure is known as OAM discovery.
