Junos OS supports IEEE 802.3ah link-fault management. Junos OS enables routers and switches to support the IEEE 802.3ah OAM standard for Ethernet interfaces in access networks. The standard defines OAM LFM. You can configure IEEE 802.3ah OAM LFM on point-to-point Ethernet links that are connected either directly or through Ethernet repeaters. The IEEE 802.3ah standard meets the requirement for OAM capabilities as Ethernet moves from being solely an enterprise technology to being a WAN and access technology, as well as being backward-compatible with existing Ethernet technology.
