Description: An entry in zxAnPonOltPerfAlmPrfConfTable. When a manager wants to create or modify an OLT 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 OLT performance alarm threshold item on different level, alarm threshold ,restore threshold and zxAnPonOltPerfAlmConfRowStatus 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: zxAnPonOltPerfRiseAlmThresh and zxAnPonOltPerfRiseAlmClrThresh, zxAnPonOltPerfRiseWarnThresh and zxAnPonOltPerfRiseWarnClrThresh, zxAnPonOltPerfFallWarnThresh and zxAnPonOltPerfFallWarnClrThresh, zxAnPonOltPerfFallAlmThresh and zxAnPonOltPerfFallAlmClrThresh.

To modify an OLT 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: zxAnPonOltPerfRiseAlmThresh and zxAnPonOltPerfRiseAlmClrThresh, zxAnPonOltPerfRiseWarnThresh and zxAnPonOltPerfRiseWarnClrThresh, zxAnPonOltPerfFallWarnThresh and zxAnPonOltPerfFallWarnClrThresh, zxAnPonOltPerfFallAlmThresh and zxAnPonOltPerfFallAlmClrThresh.

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