This read-write object specifies the disposition applied to IEEE 802.3ah Ethernet-in-the-First-Mile (EFM) OAM frames on this port's CPD profile, identified by MAC address 01:80:C2:00:00:03, Ethertype 0x8809, and subtype 03. An administrator sets this to control whether the port processes EFM OAM link-monitoring and remote-loopback frames locally, drops them, or passes them through. For example, setting this disposition to peer on an access-network facing port lets the device actively exchange EFM OAM discovery and link-monitoring frames with a connected access device.
