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.

Use Case

Device: L71FW9

Hostname,Unique serial number,Serial Number
hostname,sn,snHw
L71FW9/root,FOSVM1HHJXBALLD7/root,FOSVM1HHJXBALLD7
L71FW9/ipf,FOSVM1HHJXBALLD7/ipf,FOSVM1HHJXBALLD7

Is this a network device serial number?

In IP Fabric sn column or Unique Serial Number is an IP Fabric unique SN. In many cases the Hardware Serial Number (snHw) matches the sn however some devices that have virtualized devices will be changed to snHw/<vsys or context name>.

Example:

L71-FW12/root
role: Network Device
model: Default-fortinet
status: Active
vendor: Fortinet
location_name: L71
serial_number: FGVMEV7OFHYVLX5D_root

Note: This is an old snapshot; newer snapshots use FGVMEV7OFHYVLX5D/root instead of FGVMEV7OFHYVLX5D_root

This is an issue also with Cisco SD-WAN devices the sn and snHw are completely different.
