# NAPALM Parameters

## NAPALM_USERNAME

## NAPALM_PASSWORD

!!! tip "Dynamic Configuration Parameter"

NetBox will use these credentials when authenticating to remote devices via the supported [NAPALM integration](../integrations/napalm.md), if installed. Both parameters are optional.

!!! note
If SSH public key authentication has been set up on the remote device(s) for the system account under which NetBox runs, these parameters are not needed.

---

## NAPALM_ARGS

!!! tip "Dynamic Configuration Parameter"

A dictionary of optional arguments to pass to NAPALM when instantiating a network driver. See the NAPALM documentation for a [complete list of optional arguments](https://napalm.readthedocs.io/en/latest/support/#optional-arguments). An example:

```python
NAPALM_ARGS = {
'api_key': '472071a93b60a1bd1fafb401d9f8ef41',
'port': 2222,
}
```

Some platforms (e.g. Cisco IOS) require an argument named `secret` to be passed in addition to the normal password. If desired, you can use the configured `NAPALM_PASSWORD` as the value for this argument:

```python
NAPALM_USERNAME = 'username'
NAPALM_PASSWORD = 'MySecretPassword'
NAPALM_ARGS = {
'secret': NAPALM_PASSWORD,
# Include any additional args here
}
```

---

## NAPALM_TIMEOUT

!!! tip "Dynamic Configuration Parameter"

Default: 30 seconds

The amount of time (in seconds) to wait for NAPALM to connect to a device.

# NAPALM

NetBox supports integration with the [NAPALM automation](https://github.com/napalm-automation/napalm) library. 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"
```
