Ethernet Features
•
Fault management status and alarms.
•
Maintenance signals, such as AIS and RDI.
•
Maintenance commands, such as loopbacks and Linktrace commands.
PTP 820S is fully compliant with 802.1ag, G.8013/Y.1731, MEF-17, MEF-20, MEF-30, and MEF-31.

Connectivity Fault Management (CFM)
Note
CFM is planned for future release.
The IEEE 802.1ag and G.8013/Y.1731 standards and the MEF-17, MEF-20, MEF-30, and MEF-31
specifications define SOAM. SOAM is concerned with detecting, isolating, and reporting
connectivity faults spanning networks comprising multiple LANs, including LANs other than IEEE
802.3 media.
IEEE 802.1ag Ethernet CFM (Connectivity Fault Management) consists of three protocols that
operate together to aid in fault management:
•
Continuity check
•
Link trace
•
Loopback.
PTP 820S utilizes these protocols to maintain smooth system operation and non-stop data flow.
The following are the basic building blocks of CFM:
•
Maintenance domains, their constituent maintenance points, and the managed objects
required to create and administer them.
