Description: An entry in zxAnPonOnuPerfAlmPrfConfTable. When a manager wants to create or modify an ONU performance alarm threshold item,it must comply with the multi-variables usage rule that all the mib variables related to same fuction must be in one snmp set operation, the variables have only one type: mandatory.

Mandatory variables must be in the one snmp set operation.

To create an ONU performance alarm threshold item on different level, alarm threshold ,restore threshold and zxAnPonOnuPerfAlmConfRowStatus should be in one snmp set operation. The alarm threshold and restore threshold variables in the one snmp set operationshould be on same level. Such as: zxAnPonOnuPerfRiseAlmThresh and zxAnPonOnuPerfRiseAlmClrThresh, zxAnPonOnuPerfRiseWarnThresh and zxAnPonOnuPerfRiseWarnClrThresh, zxAnPonOnuPerfFallWarnThresh and zxAnPonOnuPerfFallWarnClrThresh, zxAnPonOnuPerfFallAlmThresh and zxAnPonOnuPerfFallAlmClrThresh.

To modify an ONU performance alarm threshold item on different level,alarm threshold and restore threshold should be also in the one snmp set operation regardless of modifying alarm or restore threshold value alone. The alarm threshold and restore threshold variables in the one snmp set operationshould be on same level. Such as: zxAnPonOnuPerfRiseAlmThresh and zxAnPonOnuPerfRiseAlmClrThresh, zxAnPonOnuPerfRiseWarnThresh and zxAnPonOnuPerfRiseWarnClrThresh, zxAnPonOnuPerfFallWarnThresh and zxAnPonOnuPerfFallWarnClrThresh, zxAnPonOnuPerfFallAlmThresh and zxAnPonOnuPerfFallAlmClrThresh.

To remove an ONU performance alarm threshold item, only zxAnPonOnuPerfAlmConfRowStatus should be set to destroy(6) while all levels of this ONU performance alarm threshold item will be removed.
