Ethernet OAM Overview
Ethernet OAM (operation, administration, and maintenance) is a tool monitoring Layer-2 link status by
sending OAM protocol data units (OAMPDUs) between devices. It helps network administrators
manage their networks effectively.
Currently, Ethernet OAM is mainly used to address common link-related issues on the “last mile.” By
enabling Ethernet OAM on two devices connected by a point-to-point connection, you can monitor the
status of the link. Ethernet OAM provides the following functions:
z
Link performance monitoring, for detecting link errors
z
Fault detection and alarm, for reporting link errors to the administrators
z
Loopback testing, for detecting link errors through non-OAMPDUs
Throughout this document, a port with Ethernet OAM enabled is called an Ethernet OAM entity or an
OAM entity.
Types of Ethernet OAMPDUs
Figure 1-1
shows the formats of different types of OAMPDUs.
