Overview of CFM

Overview of CFM

Connectivity Fault Management (CFM) supports Continuity Check (CC), Loopback (LB), and Linktrace (LT) functions.

Easy-to-use Ethernet techniques support good bandwidth extensibility on low-cost hardware. With these advantages, Ethernet services and structures are the first choice for many enterprise networks. The increasing popularity of Ethernet applications promotes the use of Ethernet Operation, Administration, and Maintenance (OAM) functions. Traditional Ethernet has poor maintainability and operability, so CFM, also called 802.1ag, solves this problem.

Figure 7-1 CFM networking

In Figure 7-1, CFM defines CC, LB, and LT functions for Ethernet networks. CFM is network-level OAM and applies to large-scale networks.
