Hardware Serial Number

[ghost]

Environment

• nautobot version: 1.5.x
• nautobot-ssot-ipfabric version: 2.0.0
• ipfabric version: 6.x

Summary

IP Fabric records two serial numbers:

• "Unique Serial Number"
  • Column sn
• "Serial Number"
  • Column snHw (Hardware Serial Number)

Nautobot has a single serial number for a device under "Hardware" with a description of "Chassis serial number".

Currently, the SSOT syncs the IPF sn and not the snHw which is not correct from the description above.

Proposed Functionality

• Add new custom field IPFabric Serial Number or IPFabric Unique Serial Number?
• Sync jobs still use the sn field as this is a unique value and ensures all data is sync'ed correctly.
• Update sync jobs to use snHw for the Device Serial Number
• Add sn data to custom field.

Open Questions

• Can Nautobot have duplicate Serial Numbers?
  • YES
• Can this be configurable?
  • CONFIG.get("default_device_serial_number", "sn" or "snHw")
• How do we migrate users?
  • SN might be an important field for their current automation.
