Serial number types for identification

Serial number types for identification

As Discovery finds CIs, their serial numbers are listed in the Serial Number [cmdb_serial_number] table so they are easy to identify. Serial number types vary depending on the CI, as described in the following examples.

Linux

In the result of dmidecode | cat, the value on the left side is what Discovery looks for. The value on the right side is how it is stored in the Serial Number [cmdb_serial_number] table.

Serial Number : system_serial_number
 
UUID : uuid_serial
 
Serial Number : baseboard_serial
 
Serial Number : chassis_serial

Windows

For Win32 WMI classes, the value on the left is the name by which it is stored in the Serial Number [cmdb_serial_number] table. The value on the right is the WMI value.

('system' : Win32_ComputerSystemProduct.IdentifyingNumber);
 
('uuid' : Win32_ComputerSystemProduct.UUID);
 
('chassis' : Win32_SystemEnclosure.SerialNumber);
 
('bios' : Win32_BIOS.SerialNumber);
 
('baseboard' : Win32_BaseBoard.SerialNumber);

SNMP

For SNMP, the mapping below is based on the code. Physical types of serial numbers are from all instances of iso.org.dod.internet.mgmt.mib-2.entityMIB.

'cisco_stack' : 'iso.org.dod.internet.private.enterprises.cisco.workgroup.ciscoStackMIB.chassisGrp.chassisSerialNumberString'
 
'cisco_chassis' : 'iso.org.dod.internet.private.enterprises.cisco.temporary.chassis.chassisId'
 
'foundry' : 'iso.org.dod.internet.private.enterprises.foundry.products.switch.snChassis.snChasGen.snChasSerNum'
 
'apc_pdu' : 'iso.org.dod.internet.private.enterprises.apc.products.hardware.masterswitch.sPDUIdent.sPDUIdentSerialNumber'
 
'printer' : 'iso.org.dod.internet.mgmt.mib-2.printmib.prtGeneral.prtGeneralEntry'
 
'standard' : 'iso.org.dod.internet.private.enterprises.apc.products.hardware.ups.upsIdent.upsAdvIdent.upsAdvIdentSerialNumber'
