This parameter is applicable for an APEX where chassis redundancy is enabled. This parameter will report the chassis redundancy configuration status. These are based on its knowledge about the secondary APEX from heartbeat messages. The APEX configured as primary will report the following values: unknown(0): Secondary configuration is not known or secondary is not connected. synchronized(1): Secondary has same configuration as primary (except for QAM outputs). outofsync(2): Secondary configuration is not in sync with primary.
