Cisco ASR 920 series Configuration Guide Ethernet Router

CHAPTER 11
Configuring Ethernet CFM
IEEE Connectivity Fault Management (CFM) is an end-to-end per-service Ethernet layer Operations,
Administration, and Maintenance (OAM) protocol. CFM includes proactive connectivity monitoring, fault
verification, and fault isolation for large Ethernet metropolitan-area networks (MANs) and WANs.
This document describes the implementation of IEEE 802.1ag Standard-Compliant CFM (IEEE CFM) in
Cisco IOS XE software. IEEE CFM together will be called “Ethernet CFM” throughout this document.
