ZXR10 2900E Series Configuration Guide
l Loopback Message (LBM): A unicast CFM protocol data unit. It is sent to a specified
MP from an MEP, expected to receive an LBR message.
l
Loopback Reply (LBR): A unicast CFM protocol data unit. It is sent by the MP receiving
an LBM as the reply to the LBM.
With the five protocol messages listed above, CFM implements the following functions:
l
Detecting faults: MEP detects network connectivity faults by periodically sending
and receiving CCM messages. The faults include connection failure and unwelcome
connection (error connection).
l
Notifying faults: After MEP detects a connectivity fault, it sends a proper alarm to the
specified management system, for example, trap messages of SNMP.
l
Locating a path: MEP locates and traces a path from an MEP to another MP (including
MEP and MIP) by using LTM/LTR messages.
l Confirming and separating a fault: This is an administrative function. The network
manager confirms the fault through LBM/LBR messages and separates the fault.
