hwInventoryParentIndex
Module: LEXMARK-MPS-MIB
OID (symbolic): LEXMARK-MPS-MIB::hwInventoryParentIndex
OID (numeric): 1.3.6.1.4.1.641.6.3.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The hwInventoryIndex of the hardware device that the item in this row is tied to. If there is no parent, this object should read 0. The base printer itself should only be used as a parent for devices that are integrated into it. ie RIP card, tray one, fax card, scanner. Items that are options such as extra input trays, external duplexers, and add on output bins should rate their own row with no parent.
Examples: 5-bin mailbox The mailbox unit as a whole would be one row, with a parent of 0. Each of the mailboxes would be row, with the parent of each mailbox pointing back to the mailbox unit. Finisher The finisher as a whole would be one row, with a parent of 0. The options of the finsher; output bins, stapler, hole punch, would each merit an individual row with the finisher unit as the parent
What is hwInventoryParentIndex?
Points to the hwInventoryIndex of the parent hardware component this row belongs to (0 if it has no parent), distinguishing integrated sub-units like a fax card from independent add-on options like an extra input tray. An admin uses this to reconstruct the physical hierarchy of a device, e.g. seeing that several output-bin rows all report the same mailbox unit as their parent.
