6.1 Diagnostic Overview

The Diagnostic screens display information to help you identify problems with the FMG.
The route between a Central Office Very-high-bit-rate Digital Subscriber Line (CO VDSL) switch and one
of its Customer-Premises Equipment (CPE) may go through switches owned by independent
organizations. A connectivity fault point generally takes time to discover and impacts subscriber's
network access. Through discovery and verification of the path, CFM can detect, analyze and isolate
connectivity faults in bridged LANs.
