About This Chapter

This chapter describes Ethernet OAM and its configurations, and how to implement link-level

Ethernet OAM detection and network-level Ethernet OAM detection to improve network

reliability. Ethernet OAM is applicable mainly to MANs.

8.1 Introduction

Ethernet OAM can effectively improve management and maintenance capabilities on Ethernet

networks, which ensures the stable network operation. Ethernet OAM is applicable mainly to

Ethernet networks.

8.2 CFM Configuration

IEEE 802.1ag, also known as Connectivity fault management (CFM), defines OAM functions

for Ethernet bearer networks. CFM applies to large-scale E2E Ethernet networks and monitor

network-wide connectivity and locate connectivity faults.

8.3 EFM Configuration

Ethernet in the First Mile (EFM) can be enabled on the devices at both ends of a point-to-point

link to monitor the connectivity and quality of the link.

8.4 Y.1731 Configuration

Y.1731 is an OAM protocol at the network layer. It provides fault detection defined in IEEE

802.1ag and performance monitoring, such as frame loss measurement, frame delay

measurement, and Alarm Indication Signal (AIS).
