Connectivity Fault Management (CFM) Feature Overview and Configuration Guide

For many years, Network Service Providers (NSPs) have managed their networks using the FCAPS model: Fault, Configuration, Accounting, Performance, and Security. Connectivity Fault Management (CFM) is an IEEE 802.1ag and ITU Y.1731 standard for managing connectivity at the Ethernet service level. The 802.1ag standard adds Fault management capabilities to Ethernet, while the ITU Y.1731 standard expands the capabilities to include Performance.
