The following are optional settings which may be declared in netbox/netbox/


NetBox will email details about critical errors to the administrators listed here. This should be a list of (name, email) tuples. For example:

    ['Hank Hill', ''],
    ['Dale Gribble', ''],

Setting these variables will display content in a banner at the top and/or bottom of the page, respectively. HTML is allowed. To replicate the content of the top banner in the bottom banner, set:

BANNER_TOP = 'Your banner text'

The value of this variable will be displayed on the login page above the login form. HTML is allowed.


Default: None

The base URL path to use when accessing NetBox. Do not include the scheme or domain name. For example, if installed at, set:

BASE_PATH = 'netbox/'


Default: False

If True, cross-origin resource sharing (CORS) requests will be accepted from all origins. If False, a whitelist will be used (see below).



These settings specify a list of origins that are authorized to make cross-site API requests. Use CORS_ORIGIN_WHITELIST to define a list of exact hostnames, or CORS_ORIGIN_REGEX_WHITELIST to define a set of regular expressions. (These settings have no effect if CORS_ORIGIN_ALLOW_ALL is True.)


Default: False

This setting enables debugging. This should be done only during development or troubleshooting. Never enable debugging on a production system, as it can expose sensitive data to unauthenticated users.


In order to send email, NetBox needs an email server configured. The following items can be defined within the EMAIL setting:

  • SERVER - Host name or IP address of the email server (use localhost if running locally)
  • PORT - TCP port to use for the connection (default: 25)
  • USERNAME - Username with which to authenticate
  • PASSSWORD - Password with which to authenticate
  • TIMEOUT - Amount of time to wait for a connection (seconds)
  • FROM_EMAIL - Sender address for emails sent by NetBox


Default: False

Enforcement of unique IP space can be toggled on a per-VRF basis. To enforce unique IP space within the global table (all prefixes and IP addresses not assigned to a VRF), set ENFORCE_GLOBAL_UNIQUE to True.


By default, all messages of INFO severity or higher will be logged to the console. Additionally, if DEBUG is False and email access has been configured, ERROR and CRITICAL messages will be emailed to the users defined in ADMINS.

The Django framework on which NetBox runs allows for the customization of logging, e.g. to write logs to file. Please consult the Django logging documentation for more information on configuring this setting. Below is an example which will write all INFO and higher messages to a file:

    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'INFO',
            'class': 'logging.FileHandler',
            'filename': '/var/log/netbox.log',
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'INFO',


Default: False

Setting this to True will permit only authenticated users to access any part of NetBox. By default, anonymous users are permitted to access most data in NetBox (excluding secrets) but not make any changes.


Default: False

Setting this to True will display a "maintenance mode" banner at the top of every page.


Default: 1000

An API consumer can request an arbitrary number of objects by appending the "limit" parameter to the URL (e.g. ?limit=1000). This setting defines the maximum limit. Setting it to 0 or None will allow an API consumer to request all objects by specifying ?limit=0.


Default: $BASE_DIR/netbox/media/

The file path to the location where media files (such as image attachments) are stored. By default, this is the netbox/media/ directory within the base NetBox installation path.



NetBox will use these credentials when authenticating to remote devices via the NAPALM library, if installed. Both parameters are optional.

Note: If SSH public key authentication has been set up for the system account under which NetBox runs, these parameters are not needed.


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. An example:

    'api_key': '472071a93b60a1bd1fafb401d9f8ef41',
    'port': 2222,

Note: 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:

NAPALM_USERNAME = 'username'
NAPALM_PASSWORD = 'MySecretPassword'
    'secret': NAPALM_PASSWORD,
    # Include any additional args here


Default: 30 seconds

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


Default: 50

Determine how many objects to display per page within each list of objects.


Default: False

When determining the primary IP address for a device, IPv6 is preferred over IPv4 by default. Set this to True to prefer IPv4 instead.


Default: $BASE_DIR/netbox/reports/

The file path to the location where custom reports will be kept. By default, this is the netbox/reports/ directory within the base NetBox installation path.


Default: UTC

The time zone NetBox will use when dealing with dates and times. It is recommended to use UTC time unless you have a specific need to use a local time zone. List of available time zones.

Date and Time Formatting

You may define custom formatting for date and times. For detailed instructions on writing format strings, please see the Django documentation.


DATE_FORMAT = 'N j, Y'               # June 26, 2016
SHORT_DATE_FORMAT = 'Y-m-d'          # 2016-06-27
TIME_FORMAT = 'g:i a'                # 1:23 p.m.
SHORT_TIME_FORMAT = 'H:i:s'          # 13:23:00
DATETIME_FORMAT = 'N j, Y g:i a'     # June 26, 2016 1:23 p.m.
SHORT_DATETIME_FORMAT = 'Y-m-d H:i'  # 2016-06-27 13:23
