Device Type Data Model

The cani device-types library follows the Nautobot device-type schema. Each YAML definition maps directly to the Nautobot data model, making inventory data portable between cani and Nautobot.

Type Categories

Device types are organized into subdirectories that map to inventory types:

Directory	Inventory Type	Go Type
device-types/	Device	CaniDeviceType
rack-types/	Rack	CaniRackType
module-types/	Module	CaniModuleType
cable-types/	Cable	CaniCableType
inventory-types/	FRU	CaniFruType

YAML Schema

Each device type definition includes:

Field	Description
manufacturer	Vendor name (e.g. HPE, Cray)
model	Model identifier (e.g. ProLiant DL380 Gen10)
slug	URL-safe unique key (e.g. hpe-proliant-dl380-gen10)
hardware-type	Classification (Device, Rack, Module, Cable)
u_height	Rack units consumed (devices and racks)
interfaces	Network interface definitions
console-ports	Serial/console port definitions
power-ports	Power input definitions
module-bays	Slots for installable modules
device-bays	Slots for child devices

Listing Available Types

Use the -L flag on any add subcommand to see what device types are currently loaded:

# List all device types
cani alpha add device -L

# List all rack types
cani alpha add rack -L

# List all module types
cani alpha add module -L
