HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
Configure the link aggregation group in 1:1 active/standby mode on Router A and Router B.
Configure Ethernet CFM on Router A, Router B, Router C, and Router D respectively. Associate
Ethernet CFM with GE 1/0/1 and GE 1/0/2 on Router A and Router B.
Assume that a connectivity fault occurs on the link between Router A and Router C. The Ethernet
CFM module detects the fault and notifies the OAM management module of the fault. The OAM
management module shuts down and then starts GE 1/0/1. This allows the link aggregation group
to sense the fault and switch the service data to the inactive link. The procedure for processing
connectivity faults on the other links is similar to that for processing the link fault between Router
A and Router C. This implements protection switching in no more than 50 ms to achieve carrier-
class reliability.

Associating Ethernet CFM with an Interface
Through the configured association between Ethernet CFM and an interface, a MEP in a
specified MA can detect a connectivity fault between the MEP and a specified RMEP within
the same MA. Then, the OAM module blocks and then unblocks the interface on which the MEP
resides so that other modules can sense the fault.
