NAPALM allows NetBox to serve a proxy for operational data, fetching live data from network devices and returning it to a requester via its REST API. Note that NetBox does not store any NAPALM data locally. + +The NetBox UI will display tabs for status, LLDP neighbors, and configuration under the device view if the following conditions are met: + +* Device status is "Active" +* A primary IP has been assigned to the device +* A platform with a NAPALM driver has been assigned +* The authenticated user has the `dcim.napalm_read_device` permission + +!!! note + To enable this integration, the NAPALM library must be installed. See [installation steps](../../installation/3-netbox/#napalm) for more information. + +Below is an example REST API request and response: + +```no-highlight +GET /api/dcim/devices/1/napalm/?method=get_environment + +{ + "get_environment": { + ... + } +} +``` + +!!! note + To make NAPALM requests via the NetBox REST API, a NetBox user must have assigned a permission granting the `napalm_read` action for the device object type. + +## Authentication + +By default, the [`NAPALM_USERNAME`](../configuration/napalm.md#napalm_username) and [`NAPALM_PASSWORD`](../configuration/napalm.md#napalm_password) configuration parameters are used for NAPALM authentication. They can be overridden for an individual API call by specifying the `X-NAPALM-Username` and `X-NAPALM-Password` headers. + +``` +$ curl "http://localhost/api/dcim/devices/1/napalm/?method=get_environment" \ +-H "Authorization: Token $TOKEN" \ +-H "Content-Type: application/json" \ +-H "Accept: application/json; indent=4" \ +-H "X-NAPALM-Username: foo" \ +-H "X-NAPALM-Password: bar" +``` + +## Method Support + +The list of supported NAPALM methods depends on the [NAPALM driver](https://napalm.readthedocs.io/en/latest/support/index.html#general-support-matrix) configured for the platform of a device. Because there is no granular mechanism in place for limiting potentially disruptive requests, NetBox supports only read-only [get](https://napalm.readthedocs.io/en/latest/support/index.html#getters-support-matrix) methods. + +## Multiple Methods + +It is possible to request the output of multiple NAPALM methods in a single API request by passing multiple `method` parameters. For example: + +```no-highlight +GET /api/dcim/devices/1/napalm/?method=get_ntp_servers&method=get_ntp_peers + +{ + "get_ntp_servers": { + ... + }, + "get_ntp_peers": { + ... + } +} +``` + +## Optional Arguments + +The behavior of NAPALM drivers can be adjusted according to the [optional arguments](https://napalm.readthedocs.io/en/latest/support/index.html#optional-arguments). NetBox exposes those arguments using headers prefixed with `X-NAPALM-`. For example, the SSH port is changed to 2222 in this API call: + +``` +$ curl "http://localhost/api/dcim/devices/1/napalm/?method=get_environment" \ +-H "Authorization: Token $TOKEN" \ +-H "Content-Type: application/json" \ +-H "Accept: application/json; indent=4" \ +-H "X-NAPALM-port: 2222" +```
