With the emergence of Gigabit Ethernet and 10-Gigabit Ethernet, Ethernet isgaining popularity in metropolitan area networks (MANs) and wide area networks (WANs) as well,increasing the need for an effective management and maintenance mechanism for Ethernet. This makesit urgent to implement Operation, Administration and Maintenance (OAM) on Ethernet networks.As a tool monitoring Layer 2 link status, Ethernet OAM mainly addresses common link-related issues onthe “last mile.” When you enable Ethernet OAM on two devices connected by a point-to-point link, youcan monitor the status of the link.Major functions of Ethernet OAMEthernet OAM is an effective tool for management and maintenance of Ethernet networks, helping toensure network stability. It includes the following major functions:• Link performance monitoring—Monitors the performance indices of a link, including packet loss,delay, and jitter, and collects traffic statistics of various types• Fault detection and alarm—Checks the connectivity of a link by sending OAM protocol data units(OAMPDUs) and reports to the network administrators when a link error occurs• Remote loopback—Checks link quality and locates link errors by looping back OAMPDUsEthernet OAMPDUsEthernet OAM works on the data link layer. Ethernet OAM reports the link status by periodicallyexchanging OAMPDUs between devices, so that the administrator can effectively manage the network.
