Configuring the Ethernet CFM OAM
On the Ethernet network, Ethernet connectivity fault management (CFM) OAM is defined as
connectivity fault management in IEEE 802.1ag to implement the OAM function of connectivity
detection on the Ethernet bearer network. Ethernet CFM OAM is applicable to the end-to-end
(E2E) network with a large scale and it is the network-level OAM.
Prerequisites
l
Network devices and lines must be in the normal state.
l
The OLT must support the Ethernet CFM OAM function.
Context
OAM is a key method of reducing network maintenance cost.
Ethernet is a widely used local area network (LAN) technology. It provides rich bandwidth,
features low cost, and supports plug-and-play and multipoint operations. As the Ethernet
technology is developing from carriers' networks to metropolitan area networks (MANs) and
wide area networks (WANs), the network management and maintenance are increasingly
important. Currently, however, Ethernet does not support carrier-class management, and thus
L2 network faults cannot be detected on Ethernet networks.
Ethernet CFM OAM is an E2E fault detection technology, which can be used to monitor,
diagnose, and troubleshoot the Ethernet.
