Purpose and Scope

ECFM (Ethernet Connectivity Fault Management) specifies the protocol entities within the architecture of Virtual Bridged LAN (Local Area Network) that provides the capabilities for detecting, verifying, and isolating connectivity failures in the Virtual Bridged LAN through CC (Continuity Check), LB (LoopBack) and LT (LinkTrace) protocols for providing complete 802.1ag functionality. Performance monitoring is done using LM (Loss Measurement), DM (Delay Measurement) functions, and TH (Throughput Measurement).

The articles in this category describe the CLI (Command Line Interface) and SNMP (Simple Network Management Protocol) configurations of ECFM to detect isolate and verify the faults in connectivity in the ECFM-managed links. It also describes the configurations related to Y.1731. The reader is expected to have a basic knowledge of the protocol as a prerequisite.
