Description: ------------ When SNMP::walk() is called with a numeric OID it provides generic results any number of times. However, as soon as it's called with the textual OID corresponding to the numeric one any subsequent calls with that numerical OID will suddenly start returning results in a different format (exactly like with the textual one). It's pretty hard to describe, however looking at the "Actual result" section clearly shows the problem. Test script: --------------- /* No simple script available due to external server being required. - \SNMP was configured with v3 protocol including auth & priv - oid_output_format = \SNMP_OID_OUTPUT_SUFFIX - exceptions_enabled = \SNMP::ERRNO_ANY - quick_print = true #1 ->walk('.1.3.6.1.4.1.6574.2.1.1', false); #2 ->walk('.1.3.6.1.4.1.6574.2.1.1', false); => result exactly like in #1 #3 ->walk('SYNOLOGY-DISK-MIB::diskTable', false); => result with names #4 ->walk('.1.3.6.1.4.1.6574.2.1.1', false); => result like in #3 instead of #1-#2 */ Actual result: -------------- $snmp->walk('.1.3.6.1.4.1.6574.2.1.1', false); array ( 'synology.2.1.1.2.0' => '"Drive 1"', 'synology.2.1.1.2.1' => '"Drive 2"', 'synology.2.1.1.2.2' => '"Drive 3"', 'synology.2.1.1.2.3' => '"Drive 4"', 'synology.2.1.1.2.4' => '"Drive 5"', 'synology.2.1.1.3.0' => '"WD40EFRX-68WT0N0 "', 'synology.2.1.1.3.1' => '"WD40EFRX-68N32N0 "', 'synology.2.1.1.3.2' => '"ST6000VN0033-2EE110 "', 'synology.2.1.1.3.3' => '"WD60EFRX-68L0BN1 "', 'synology.2.1.1.3.4' => '"ST1000LM010-9YH146 "', 'synology.2.1.1.4.0' => '"SATA"', 'synology.2.1.1.4.1' => '"SATA"', 'synology.2.1.1.4.2' => '"SATA"', 'synology.2.1.1.4.3' => '"SATA"', 'synology.2.1.1.4.4' => '"SATA"', 'synology.2.1.1.5.0' => '1', 'synology.2.1.1.5.1' => '1', 'synology.2.1.1.5.2' => '1', 'synology.2.1.1.5.3' => '1', 'synology.2.1.1.5.4' => '1', 'synology.2.1.1.6.0' => '37', 'synology.2.1.1.6.1' => '34', 'synology.2.1.1.6.2' => '39', 'synology.2.1.1.6.3' => '37', 'synology.2.1.1.6.4' => '31', ) $snmp->walk('SYNOLOGY-DISK-MIB::diskTable', false); array ( 'diskID.0' => '"Drive 1"', 'diskID.1' => '"Drive 2"', 'diskID.2' => '"Drive 3"', 'diskID.3' => '"Drive 4"', 'diskID.4' => '"Drive 5"', 'diskModel.0' => '"WD40EFRX-68WT0N0 "', 'diskModel.1' => '"WD40EFRX-68N32N0 "', 'diskModel.2' => '"ST6000VN0033-2EE110 "', 'diskModel.3' => '"WD60EFRX-68L0BN1 "', 'diskModel.4' => '"ST1000LM010-9YH146 "', 'diskType.0' => '"SATA"', 'diskType.1' => '"SATA"', 'diskType.2' => '"SATA"', 'diskType.3' => '"SATA"', 'diskType.4' => '"SATA"', 'diskStatus.0' => '1', 'diskStatus.1' => '1', 'diskStatus.2' => '1', 'diskStatus.3' => '1', 'diskStatus.4' => '1', 'diskTemperature.0' => '37', 'diskTemperature.1' => '34', 'diskTemperature.2' => '39', 'diskTemperature.3' => '37', 'diskTemperature.4' => '31', ) $snmp->walk('.1.3.6.1.4.1.6574.2.1.1', false); array ( 'diskID.0' => '"Drive 1"', 'diskID.1' => '"Drive 2"', 'diskID.2' => '"Drive 3"', 'diskID.3' => '"Drive 4"', 'diskID.4' => '"Drive 5"', 'diskModel.0' => '"WD40EFRX-68WT0N0 "', 'diskModel.1' => '"WD40EFRX-68N32N0 "', 'diskModel.2' => '"ST6000VN0033-2EE110 "', 'diskModel.3' => '"WD60EFRX-68L0BN1 "', 'diskModel.4' => '"ST1000LM010-9YH146 "', 'diskType.0' => '"SATA"', 'diskType.1' => '"SATA"', 'diskType.2' => '"SATA"', 'diskType.3' => '"SATA"', 'diskType.4' => '"SATA"', 'diskStatus.0' => '1', 'diskStatus.1' => '1', 'diskStatus.2' => '1', 'diskStatus.3' => '1', 'diskStatus.4' => '1', 'diskTemperature.0' => '37', 'diskTemperature.1' => '34', 'diskTemperature.2' => '39', 'diskTemperature.3' => '37', 'diskTemperature.4' => '31', )
