802.3ah

802.3ah, an IEEE Data-link OAM specification, provides utilities for monitoring and troubleshooting Ethernet links, which are vital for carrier deployment. The IEEE 802.3ah EFM specification defines OAM as an optional sublayer just above the Ethernet media access controller (MAC). The OAM sublayer consists of a parser block, a multiplexer block, and a control block. All three blocks communicate with an OAM client, which is the "brains of the IEEE 802.3ah management architecture.
