Impact on the System

After OAM is deployed and an APS instance is bound to the PW protection group:

The service traffic will be switched from the primary PW to the secondary PW if OAM reports an alarm about the primary PW.
The service traffic will not be switched or affected if OAM reports an alarm about the secondary PW.

Possible Causes

The MEG names configured on the local and remote MEPs were different.

Procedure
