Closes: #9906
- Adds `color` field to front and rearport template import forms
- Adds `color` field to `to_yaml` export for front and rearport
templates
Prefetch the Tenant Group in views which allows its table to be configured
by the user. This decreases the amount of database queries that are required
to fetch the data.
Configure the prefetch to also include the Tenant Group, avoids additional
database queries when the Tenant Group column is to be rendered.
NOTE: If no personalisation of the global search tables should be done,
this commit can be reverted.
Replaces all usages of the TenantColumn with the new TenancyColumnsMixin.
This enables the user to add a column for Tenant Group on all tables which
also has a column for Tenant.
Works the same as the existing TenantColumn, but displats the Tenant Group of
the Tenant.
Views should prefetch the Tenants Group for this to be efficient in large
tables.

Fixes#8920
Limits the amount of non-racked devices on Site and Location view to 10 and provides a link to the device list this is pre-filtered to the relevant site or location.
When using permissions that use tags, a user may receive multiple permissions
of the same type if multiple tags are assigned to the device. This causes the
RestrictedQuerySet class to generate a query similar to this:
>>> dcim.models.Device.objects.filter(Q(tags__name='tag1')|Q(tags__name='tag2'))
<ConfigContextModelQuerySet [<Device: device1>, <Device: device1>]>
This query returns the same object twice if both tags are assigned to it. This
is due to the use of the django-taggit library. The library's documentation
describes this behavior as expected and suggests using an explicit distinct()
call in queries to avoid duplicates.
However, the use of DISTINCT in queries has a global side effect -
deduplication of responses, which may or may not be acceptable behavior
(depending on further use). Since it is not known how RestrictedQuerySet will
be used in the rest of the code, it was decided to dedupe using a subquery.
In the current documentation we have two seemingly conflicting sentences:
* REMOTE_AUTH_DEFAULT_GROUPS: (Requires REMOTE_AUTH_ENABLED.)
* REMOTE_AUTH_ENABLED: (REMOTE_AUTH_DEFAULT_GROUPS will not function if REMOTE_AUTH_ENABLED is enabled)
* Fixes#8398: Add ConfigParam.size to enlarge specific config fields

* Hierarchical regions, site groups, sites, and locations
* Racks, devices, and device components
* Cables and wireless connections
* Power distribution
* Data circuits and providers
* Virtual machines and clusters
* IP prefixes, ranges, and addresses
* VRFs and route targets
* FHRP groups (VRRP, HSRP, etc.)
* AS numbers
* VLANs and scoped VLAN groups
* Organizational tenants and contacts
In addition to its extensive built-in models and functionality, NetBox can be
customized and extended through the use of:
* Custom fields
* Custom links
* Configuration contexts
* Custom model validation rules
* Reports
* Custom scripts
* Export templates
* Conditional webhooks
* Plugins
* Single sign-on (SSO) authentication

## Authentication
By default, the [`NAPALM_USERNAME`](../configuration/optional-settings.md#napalm_username) and [`NAPALM_PASSWORD`](../configuration/optional-settings.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.
By default, the [`NAPALM_USERNAME`](../configuration/dynamic-settings.md#napalm_username) and [`NAPALM_PASSWORD`](../configuration/dynamic-settings.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.
A webhook may include a set of conditional logic expressed in JSON used to control whether a webhook triggers for a specific object. For example, you may wish to trigger a webhook for devices only when the `status` field of an object is "active":
```json
{
"and":[
{
"attr":"status.value",
"value":"active"
}
]
}
```
For more detail, see the reference documentation for NetBox's [conditional logic](../reference/conditions.md).
## Webhook Processing
When a change is detected, any resulting webhooks are placed into a Redis queue for processing. This allows the user's request to complete without needing to wait for the outgoing webhook(s) to be processed. The webhooks are then extracted from the queue by the `rqworker` process and HTTP requests are sent to their respective destinations. The current webhook queue and any failed webhooks can be inspected in the admin UI under System > Background Tasks.
This guide explains how to configure single sign-on (SSO) support for NetBox using [Microsoft Azure Active Directory (AD)](https://azure.microsoft.com/en-us/services/active-directory/) as an authentication backend.
## Azure AD Configuration
### 1. Create a test user (optional)
Create a new user in AD to be used for testing. You can skip this step if you already have a suitable account created.
### 2. Create an app registration
Under the Azure Active Directory dashboard, navigate to **Add > App registration**.
Enter a name for the registration (e.g. "NetBox") and ensure that the "single tenant" option is selected.
Under "Redirect URI", select "Web" for the platform and enter the path to your NetBox installation, ending with `/oauth/complete/azuread-oauth2/`. Note that this URI **must** begin with `https://` unless you are referencing localhost (for development purposes).
NetBox also supports multitenant authentication via Azure AD, however it requires a different backend and an additional configuration parameter. Please see the [`python-social-auth` documentation](https://python-social-auth.readthedocs.io/en/latest/backends/azuread.html#tenant-support) for details concerning multitenant authentication.
### 3. Create a secret
When viewing the newly-created app registration, click the "Add a certificate or secret" link under "Client credentials". Under the "Client secrets" tab, click the "New client secret" button.
You can optionally specify a description and select a lifetime for the secret.
Restart the NetBox services so that the new configuration takes effect. This is typically done with the command below:
```no-highlight
sudo systemctl restart netbox
```
## Testing
Log out of NetBox if already authenticated, and click the "Log In" button at top right. You should see the normal login form as well as an option to authenticate using Azure AD. Click that link.
You should be redirected to Microsoft's authentication portal. Enter the username/email and password of your test account to continue. You may also be prompted to grant this application access to your account.
If successful, you will be redirected back to the NetBox UI, and will be logged in as the AD user. You can verify this by navigating to your profile (using the button at top right).
This user account has been replicated locally to NetBox, and can now be assigned groups and permissions within the NetBox admin UI.
## Troubleshooting
### Redirect URI does not Match
Azure requires that the authenticating client request a redirect URI that matches what you've configured for the app in step two. This URI **must** begin with `https://` (unless using `localhost` for the domain).
If Azure complains that the requested URI starts with `http://` (not HTTPS), it's likely that your HTTP server is misconfigured or sitting behind a load balancer, so NetBox is not aware that HTTPS is being use. To force the use of an HTTPS redirect URI, set `SOCIAL_AUTH_REDIRECT_IS_HTTPS = True` in `configuration.py` per the [python-social-auth docs](https://python-social-auth.readthedocs.io/en/latest/configuration/settings.html#processing-redirects-and-urlopen).
### Not Logged in After Authenticating
If you are redirected to the NetBox UI after authenticating successfully, but are _not_ logged in, double-check the configured backend and app registration. The instructions in this guide pertain only to the `azuread.AzureADOAuth2` backend using a single-tenant app registration.
This guide explains how to configure single sign-on (SSO) support for NetBox using [Okta](https://www.okta.com/) as an authentication backend.
## Okta Configuration
!!! tip "Okta developer account"
Okta offers free developer accounts at <https://developer.okta.com/>.
### 1. Create a test user (optional)
Create a new user in the Okta admin portal to be used for testing. You can skip this step if you already have a suitable account created.
### 2. Create an app registration
Within the Okta administration dashboard, navigate to **Applications > Applications**, and click the "Create App Integration" button. Select "OIDC" as the sign-in method, and "Web application" for the application type.
On the next page, give the app integration a name (e.g. "NetBox") and specify the sign-in and sign-out URIs. These URIs should follow the formats below:
Restart the NetBox services so that the new configuration takes effect. This is typically done with the command below:
```no-highlight
sudo systemctl restart netbox
```
## Testing
Log out of NetBox if already authenticated, and click the "Log In" button at top right. You should see the normal login form as well as an option to authenticate using Okta. Click that link.
You should be redirected to Okta's authentication portal. Enter the username/email and password of your test account to continue. You may also be prompted to grant this application access to your account.
If successful, you will be redirected back to the NetBox UI, and will be logged in as the Okta user. You can verify this by navigating to your profile (using the button at top right).
This user account has been replicated locally to NetBox, and can now be assigned groups and permissions within the NetBox admin UI.
Local user accounts and groups can be created in NetBox under the "Authentication and Authorization" section of the administrative user interface. This interface is available only to users with the "staff" permission enabled.
At a minimum, each user account must have a username and password set. User accounts may also denote a first name, last name, and email address. [Permissions](../permissions.md) may also be assigned to users and/or groups within the admin UI.
## Remote Authentication
NetBox may be configured to provide user authenticate via a remote backend in addition to local authentication. This is done by setting the `REMOTE_AUTH_BACKEND` configuration parameter to a suitable backend class. NetBox provides several options for remote authentication.
NetBox includes an authentication backend which supports LDAP. See the [LDAP installation docs](../../installation/6-ldap.md) for more detail about this backend.
Another option for remote authentication in NetBox is to enable HTTP header-based user assignment. The front end HTTP server (e.g. nginx or Apache) performs client authentication as a process external to NetBox, and passes information about the authenticated user via HTTP headers. By default, the user is assigned via the `REMOTE_USER` header, but this can be customized via the `REMOTE_AUTH_HEADER` configuration parameter.
NetBox supports single sign-on authentication via the [python-social-auth](https://github.com/python-social-auth) library. To enable SSO, specify the path to the desired authentication backend within the `social_core` Python package. Please see the complete list of [supported authentication backends](https://github.com/python-social-auth/social-core/tree/master/social_core/backends) for the available options.
Most remote authentication backends require some additional configuration through settings prefixed with `SOCIAL_AUTH_`. These will be automatically imported from NetBox's `configuration.py` file. Additionally, the [authentication pipeline](https://python-social-auth.readthedocs.io/en/latest/pipeline.html) can be customized via the `SOCIAL_AUTH_PIPELINE` parameter. (NetBox's default pipeline is defined in `netbox/settings.py` for your reference.)
NetBox v3.2.3 and later support native integration with [Sentry](https://sentry.io/) for automatic error reporting. To enable this functionality, simply set `SENTRY_ENABLED` to True in `configuration.py`. Errors will be sent to a Sentry ingestor maintained by the NetBox team for analysis.
```python
SENTRY_ENABLED=True
```
### Using a Custom DSN
If you prefer instead to use your own Sentry ingestor, you'll need to first create a new project under your Sentry account to represent your NetBox deployment and obtain its corresponding data source name (DSN). This looks like a URL similar to the example below:
```
https://examplePublicKey@o0.ingest.sentry.io/0
```
Once you have obtained a DSN, configure Sentry in NetBox's `configuration.py` file with the following parameters:
You can optionally attach one or more arbitrary tags to the outgoing error reports if desired by setting the `SENTRY_TAGS` parameter:
```python
SENTRY_TAGS={
"custom.foo":"123",
"custom.bar":"abc",
}
```
!!! warning "Reserved tag prefixes"
Avoid using any tag names which begin with `netbox.`, as this prefix is reserved by the NetBox application.
### Testing
Once the configuration has been saved, restart the NetBox service.
To test Sentry operation, try generating a 404 (page not found) error by navigating to an invalid URL, such as `https://netbox/404-error-testing`. (Be sure that debug mode has been disabled.) After receiving a 404 response from the NetBox server, you should see the issue appear shortly in Sentry.
NetBox includes a `housekeeping` management command that should be run nightly. This command handles:
* Clearing expired authentication sessions from the database
* Deleting changelog records older than the configured [retention time](../configuration/optional-settings.md#changelog_retention)
* Deleting changelog records older than the configured [retention time](../configuration/dynamic-settings.md#changelog_retention)
* Deleting job result records older than the configured [retention time](../configuration/dynamic-settings.md#jobresult_retention)
This command can be invoked directly, or by using the shell script provided at `/opt/netbox/contrib/netbox-housekeeping.sh`. This script can be copied into your cron scheduler's daily jobs directory (e.g. `/etc/cron.daily`) or referenced directly within the cron configuration file.
This command can be invoked directly, or by using the shell script provided at `/opt/netbox/contrib/netbox-housekeeping.sh`. This script can be linked from your cron scheduler's daily jobs directory (e.g. `/etc/cron.daily`) or referenced directly within the cron configuration file.
The `housekeeping` command can also be run manually at any time: Running the command outside of scheduled execution times will not interfere with its operation.
On Debian-based systems, be sure to omit the `.sh` file extension when linking to the script from within a cron directory. Otherwise, the task may not run.
The `housekeeping` command can also be run manually at any time: Running the command outside scheduled execution times will not interfere with its operation.
NetBox v2.9 introduced a new object-based permissions framework, which replace's Django's built-in permissions model. Object-based permissions enable an administrator to grant users or groups the ability to perform an action on arbitrary subsets of objects in NetBox, rather than all objects of a certain type. For example, it is possible to grant a user permission to view only sites within a particular region, or to modify only VLANs with a numeric ID within a certain range.

## BANNER_TOP
## BANNER_BOTTOM
Setting these variables will display custom 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:
```python
BANNER_TOP='Your banner text'
BANNER_BOTTOM=BANNER_TOP
```
---
## BANNER_LOGIN
This defines custom content to be displayed on the login page above the login form. HTML is allowed.
---
## CHANGELOG_RETENTION
Default: 90
The number of days to retain logged changes (object creations, updates, and deletions). Set this to `0` to retain
changes in the database indefinitely.
!!! warning
If enabling indefinite changelog retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.
---
## CUSTOM_VALIDATORS
This is a mapping of models to [custom validators](../customization/custom-validation.md) that have been defined locally to enforce custom validation logic. An example is provided below:
```python
CUSTOM_VALIDATORS={
"dcim.site":[
{
"name":{
"min_length":5,
"max_length":30
}
},
"my_plugin.validators.Validator1"
],
"dim.device":[
"my_plugin.validators.Validator1"
]
}
```
---
## DEFAULT_USER_PREFERENCES
This is a dictionary defining the default preferences to be set for newly-created user accounts. For example, to set the default page size for all users to 100, define the following:
```python
DEFAULT_USER_PREFERENCES={
"pagination":{
"per_page":100
}
}
```
For a complete list of available preferences, log into NetBox and navigate to `/user/preferences/`. A period in a preference name indicates a level of nesting in the JSON data. The example above maps to `pagination.per_page`.
---
## ENFORCE_GLOBAL_UNIQUE
Default: False
By default, NetBox will permit users to create duplicate prefixes and IP addresses in the global table (that is, those which are not assigned to any VRF). This behavior can be disabled by setting `ENFORCE_GLOBAL_UNIQUE` to True.
---
## GRAPHQL_ENABLED
Default: True
Setting this to False will disable the GraphQL API.
---
## JOBRESULT_RETENTION
Default: 90
The number of days to retain job results (scripts and reports). Set this to `0` to retain
job results in the database indefinitely.
!!! warning
If enabling indefinite job results retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.
---
## MAINTENANCE_MODE
Default: False
Setting this to True will display a "maintenance mode" banner at the top of every page. Additionally, NetBox will no longer update a user's "last active" time upon login. This is to allow new logins when the database is in a read-only state. Recording of login times will resume when maintenance mode is disabled.
This specifies the URL to use when presenting a map of a physical location by street address or GPS coordinates. The URL must accept either a free-form street address or a comma-separated pair of numeric coordinates appended to it.
---
## MAX_PAGE_SIZE
Default: 1000
A web user or API consumer can request an arbitrary number of objects by appending the "limit" parameter to the URL (e.g. `?limit=1000`). This parameter defines the maximum acceptable limit. Setting this to `0` or `None` will allow a client to retrieve _all_ matching objects at once with no limit by specifying `?limit=0`.
---
## NAPALM_USERNAME
## NAPALM_PASSWORD
NetBox will use these credentials when authenticating to remote devices via the supported [NAPALM integration](../additional-features/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
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
Default: 30 seconds
The amount of time (in seconds) to wait for NAPALM to connect to a device.
---
## PAGINATE_COUNT
Default: 50
The default maximum number of objects to display per page within each list of objects.
---
## POWERFEED_DEFAULT_AMPERAGE
Default: 15
The default value for the `amperage` field when creating new power feeds.
---
## POWERFEED_DEFAULT_MAX_UTILIZATION
Default: 80
The default value (percentage) for the `max_utilization` field when creating new power feeds.
---
## POWERFEED_DEFAULT_VOLTAGE
Default: 120
The default value for the `voltage` field when creating new power feeds.
---
## PREFER_IPV4
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.
---
## RACK_ELEVATION_DEFAULT_UNIT_HEIGHT
Default: 22
Default height (in pixels) of a unit within a rack elevation. For best results, this should be approximately one tenth of `RACK_ELEVATION_DEFAULT_UNIT_WIDTH`.
---
## RACK_ELEVATION_DEFAULT_UNIT_WIDTH
Default: 220
Default width (in pixels) of a unit within a rack elevation.
Set to True to enable automatic error reporting via [Sentry](https://sentry.io/).
---
## SENTRY_SAMPLE_RATE
Default: 1.0 (all)
The sampling rate for errors. Must be a value between 0 (disabled) and 1.0 (report on all errors).
---
## SENTRY_TAGS
An optional dictionary of tag names and values to apply to Sentry error reports.For example:
```
SENTRY_TAGS = {
"custom.foo": "123",
"custom.bar": "abc",
}
```
!!! warning "Reserved tag prefixes"
Avoid using any tag names which begin with `netbox.`, as this prefix is reserved by the NetBox application.
---
## SENTRY_TRACES_SAMPLE_RATE
Default: 0 (disabled)
The sampling rate for transactions. Must be a value between 0 (disabled) and 1.0 (report on all transactions).
!!! warning "Consider performance implications"
A high sampling rate for transactions can induce significant performance penalties. If transaction reporting is desired, it is recommended to use a relatively low sample rate of 10% to 20% (0.1 to 0.2).

## ENFORCE_GLOBAL_UNIQUE
Default: False
By default, NetBox will permit users to create duplicate prefixes and IP addresses in the global table (that is, those which are not assigned to any VRF). This behavior can be disabled by setting `ENFORCE_GLOBAL_UNIQUE` to True.
Some static choice fields on models can be configured with custom values. This is done by defining `FIELD_CHOICES` as a dictionary mapping model fields to their choices. Each choice in the list must have a database value and a human-friendly label, and may optionally specify a color. (A list of available colors is provided below.)
Setting this to False will disable the GraphQL API.
The choices provided can either replace the stock choices provided by NetBox, or append to them. To _replace_ the available choices, specify the app, model, and field name separated by dots. For example, the site model would be referenced as `dcim.Site.status`. To _extend_ the available choices, append a plus sign to the end of this string (e.g. `dcim.Site.status+`).
For example, the following configuration would replace the default site status choices with the options Foo, Bar, and Baz:
```python
FIELD_CHOICES = {
'dcim.Site.status': (
('foo', 'Foo', 'red'),
('bar', 'Bar', 'green'),
('baz', 'Baz', 'blue'),
)
}
```
Appending a plus sign to the field identifier would instead _add_ these choices to the ones already offered:
```python
FIELD_CHOICES = {
'dcim.Site.status+': (
...
)
}
```
The following model fields support configurable choices:
* `circuits.Circuit.status`
* `dcim.Device.status`
* `dcim.PowerFeed.status`
* `dcim.Rack.status`
* `dcim.Site.status`
* `extras.JournalEntry.kind`
* `ipam.IPAddress.status`
* `ipam.IPRange.status`

Custom validators are associated with specific NetBox models under the [CUSTOM_VALIDATORS](../configuration/dynamic-settings.md#custom_validators) configuration parameter. There are three manners by which custom validation rules can be defined:

2. Dotted path to a custom validator class
3. Direct reference to a custom validator class

!!! info "IDE Integration"
Some IDEs, such as PyCharm, will integrate with Django's development server and allow you to run it directly within the IDE. This is strongly encouraged as it makes for a much more convenient development environment.
## Populating Demo Data
Once you have your development environment up and running, it might be helpful to populate some "dummy" data to make interacting with the UI and APIs more convenient. Check out the [netbox-demo-data](https://github.com/netbox-community/netbox-demo-data) repo on GitHub, which houses a collection of sample data that can be easily imported to any new NetBox deployment. (This sample data is used to populate the public demo instance at <https://demo.netbox.dev>.)
The demo data is provided in JSON format and loaded into an empty database using Django's `loaddata` management command. Consult the demo data repo's `README` file for complete instructions on populating the data.
## Running Tests
Throughout the course of development, it's a good idea to occasionally run NetBox's test suite to catch any potential errors. Tests are run using the `test` management command:
Prior to committing any substantial changes to the code base, be sure to run NetBox's test suite to catch any potential errors. Tests are run using the `test` management command, which employs Python's [`unittest`](https://docs.python.org/3/library/unittest.html#module-unittest) library. Remember to ensure the Python virtual environment is active before running this command. Also keep in mind that these commands are executed in the `netbox/` directory, not the root directory of the repository.
To avoid potential issues with your local configuration file, set the `NETBOX_CONFIGURATION` to point to the packaged test configuration at `netbox/configuration_testing.py`. This will handle things like ensuring that the dummy plugin is enabled for comprehensive testing.
In cases where you haven't made any changes to the database (which is most of the time), you can append the `--keepdb` argument to this command to reuse the test database between runs. This cuts down on the time it takes to run the test suite since the database doesn't have to be rebuilt each time. (Note that this argument will cause errors if you've modified any model fields since the previous test run.)
In cases where you haven't made any changes to the database schema (which is typical), you can append the `--keepdb` argument to this command to reuse the test database between runs. This cuts down on the time it takes to run the test suite since the database doesn't have to be rebuilt each time. (Note that this argument will cause errors if you've modified any model fields since the previous test run.)
```no-highlight
$ python netbox/manage.py test --keepdb
$ python manage.py test --keepdb
```
You can also reduce testing time by enabling parallel test execution with the `--parallel` flag. (By default, this will run as many parallel tests as you have processors. To avoid sluggishness, it's a good idea to specify a lower number of parallel tests.) This flag can be combined with `--keepdb`, although if you encounter any strange errors, try running the test suite again with parallelization disabled.
```no-highlight
$ python manage.py test --parallel <n>
```
Finally, it's possible to limit the run to a specific set of tests, specified by their Python path. For example, to run only IPAM and DCIM view tests:
```no-highlight
$ python manage.py test dcim.tests.test_views ipam.tests.test_views
```
This is handy for instances where just a few tests are failing and you want to re-run them individually.

If you notice in the course of unrelated work a pattern that should be corrected, continue to follow the pattern for now and submit a separate bug report so that the entire code base can be evaluated at a later point.
* Prioritize readability over concision. Python is a very flexible language that typically offers several options for expressing a given piece of logic, but some may be more friendly to the reader than others. (List comprehensions are particularly vulnerable to over-optimization.) Always remain considerate of the future reader who may need to interpret your code without the benefit of the context within which you are writing it.

See the [installation guide](installation/index.md) for help getting NetBox up and running quickly.
Minor NetBox releases (e.g. v3.1) are published three times a year; in April, August, and December. These typically introduce major new features and may contain breaking API changes. Patch releases are published roughly every one to two weeks to resolve bugs and fulfill minor feature requests. These are backward-compatible with previous releases unless otherwise noted. The NetBox maintainers strongly recommend running the latest stable release whenever possible.

A cable may be traced from either of its endpoints by clicking the "trace" button. (A REST API endpoint also provides this functionality.) NetBox will follow the path of connected cables from this termination across the directly connected cable to the far-end termination. If the cable connects to a pass-through port, and the peer port has another cable connected, NetBox will continue following the cable path until it encounters a non-pass-through or unconnected termination point. The entire path will be displayed to the user.

Device types are instantiated as devices installed within sites and/or equipment racks.

You can then create multiple _instances_ of this type named "switch1," "switch2," and so on. Each device will automatically inherit the components (such as interfaces) of its device type at the time of creation. However, changes made to a device type will **not** apply to instances of that device type retroactively.

A device type may optionally specify an airflow direction, such as front-to-rear, rear-to-front, or passive. Airflow direction may also be set separately per device. If it is not defined for a device at the time of its creation, it will inherit the airflow setting of its device type.
Interfaces in NetBox represent network interfaces used to exchange data with connected devices. On modern networks, these are most commonly Ethernet, but other types are supported as well. Each interface must be assigned a type, and may optionally be assigned a MAC address, MTU, and IEEE 802.1Q mode (tagged or access). Each interface can also be enabled or disabled, and optionally designated as management-only (for out-of-band management).

Physical interfaces may be arranged into a link aggregation group (LAG) and associated with a parent LAG (virtual) interface. LAG interfaces can be recursively nested to model bonding of trunk groups. Like all virtual interfaces, LAG interfaces cannot be connected physically.
### Wireless Interfaces
Wireless interfaces may additionally track the following attributes:
* **Role** - AP or station
* **Channel** - One of several standard wireless channels
* **Channel Frequency** - The transmit frequency
* **Channel Width** - Channel bandwidth
If a predefined channel is selected, the frequency and width attributes will be assigned automatically. If no channel is selected, these attributes may be defined manually.
### IP Address Assignment
IP addresses can be assigned to interfaces. VLANs can also be assigned to each interface as either tagged or untagged. (An interface may have only one untagged VLAN.)
Inventory items represent hardware components installed within a device, such as a power supply or CPU or line card. Inventory items are distinct from other device components in that they cannot be templatized on a device type, and cannot be connected by cables. They are intended to be used primarily for inventory purposes.
Inventory items represent hardware components installed within a device, such as a power supply or CPU or line card. They are intended to be used primarily for inventory purposes.

For example, an inventory item might be created to represent a line card which houses several SFP optics, each of which exists as a child item within the device. An inventory item may also be associated with a specific component within the same device. For example, you may wish to associate a transceiver with an interface.
Inventory items can be organized by functional roles, which are fully customizable by the user. For example, you might create roles for power supplies, fans, interface optics, etc.
A template for an inventory item that will be automatically created when instantiating a new device. All attributes of this object will be copied to the new inventory item, including the associations with a parent item and assigned component, if any.
Racks and devices can be grouped by location within a site. A location may represent a floor, room, cage, or similar organizational unit. Locations can be nested to form a hierarchy. For example, you may have floors within a site, and rooms within a floor.
The name and facility ID of each rack within a location must be unique. (Racks not assigned to the same location may have identical names and/or facility IDs.)
Each location must have a name that is unique within its parent site and location, if any.
A module is a field-replaceable hardware component installed within a device which houses its own child components. The most common example is a chassis-based router or switch.
Similar to devices, modules are instantiated from module types, and any components associated with the module type are automatically instantiated on the new model. Each module must be installed within a module bay on a device, and each module bay may have only one module installed in it. A module may optionally be assigned a serial number and asset tag.
Module bays represent a space or slot within a device in which a field-replaceable module may be installed. A common example is that of a chassis-based switch such as the Cisco Nexus 9000 or Juniper EX9200. Modules in turn hold additional components that become available to the parent device.
A template for a module bay that will be created on all instantiations of the parent device type. Module bays hold installed modules that do not have an independent management plane, such as line cards.
A module type represent a specific make and model of hardware component which is installable within a device and has its own child components. For example, consider a chassis-based switch or router with a number of field-replaceable line cards. Each line card has its own model number and includes a certain set of components such as interfaces. Each module type may have a manufacturer, model number, and part number assigned to it.
Similar to device types, each module type can have any of the following component templates associated with it:
* Interfaces
* Console ports
* Console server ports
* Power ports
* Power Outlets
* Front pass-through ports
* Rear pass-through ports
Note that device bays and module bays may _not_ be added to modules.
## Automatic Component Renaming
When adding component templates to a module type, the string `{module}` can be used to reference the `position` field of the module bay into which an instance of the module type is being installed.
For example, you can create a module type with interface templates named `Gi{module}/0/[1-48]`. When a new module of this type is "installed" to a module bay with a position of "3", NetBox will automatically name these interfaces `Gi3/0/[1-48]`.
Automatic renaming is supported for all modular component types (those listed above).
The rack model represents a physical two- or four-post equipment rack in which devices can be installed. Each rack must be assigned to a site, and may optionally be assigned to a location and/or tenant. Racks can also be organized by user-defined functional roles.

Each rack must be assigned to a site, and may optionally be assigned to a location and/or tenant. Racks can also be organized by user-defined functional roles. The name and facility ID of each rack within a location must be unique.
Rack height is measured in *rack units* (U); racks are commonly between 42U and 48U tall, but NetBox allows you to define racks of arbitrary height. A toggle is provided to indicate whether rack units are in ascending (from the ground up) or descending order.
Sites can be arranged geographically using regions. A region might represent a continent, country, city, campus, or other area depending on your use case. Regions can be nested recursively to construct a hierarchy. For example, you might define several country regions, and within each of those several state or city regions to which sites are assigned.
Each region must have a name that is unique within its parent region, if any.
Like regions, site groups can be used to organize sites. Whereas regions are intended to provide geographic organization, site groups can be used to classify sites by role or function. Also like regions, site groups can be nested to form a hierarchy. Sites which belong to a child group are also considered to be members of any of its parent groups.
Each site group must have a name that is unique within its parent group, if any.
A virtual chassis represents a set of devices which share a common control plane. A common example of this is a stack of switches which are connected and configured to operate as a single device. A virtual chassis must be assigned a name and may be assigned a domain.
Each device in the virtual chassis is referred to as a VC member, and assigned a position and (optionally) a priority. VC member devices commonly reside within the same rack, though this is not a requirement. One of the devices may be designated as the VC master: This device will typically be assigned a name, services, and other attributes related to managing the VC.

It's important to recognize the distinction between a virtual chassis and a chassis-based device. A virtual chassis is **not** suitable for modeling a chassis-based switch with removable line cards (such as the Juniper EX9208), as its line cards are _not_ physically autonomous devices.

A webhook is a mechanism for conveying to some external system a change that took place in NetBox. For example, you may want to notify a monitoring system whenever the status of a device is updated in NetBox. This can be done by creating a webhook for the device model in NetBox and identifying the webhook receiver. When NetBox detects a change to a device, an HTTP request containing the details of the change and who made it be sent to the specified receiver. Webhooks are managed under Logging > Webhooks.

ASN is short for Autonomous System Number. This identifier is used in the BGP protocol to identify which "autonomous system" a particular prefix is originating and transiting through.
The AS number model within NetBox allows you to model some of this real-world relationship.
Within NetBox:
* AS numbers are globally unique
* Each AS number must be associated with a RIR (ARIN, RFC 6996, etc)
* Each AS number can be associated with many different sites
* Each site can have many different AS numbers
* Each AS number can be assigned to a single tenant
A first-hop redundancy protocol (FHRP) enables multiple physical interfaces to present a virtual IP address in a redundant manner. Example of such protocols include:
* Hot Standby Router Protocol (HSRP)
* Virtual Router Redundancy Protocol (VRRP)
* Common Address Redundancy Protocol (CARP)
* Gateway Load Balancing Protocol (GLBP)
NetBox models these redundancy groups by protocol and group ID. Each group may optionally be assigned an authentication type and key. (Note that the authentication key is stored as a plaintext value in NetBox.) Each group may be assigned or more virtual IPv4 and/or IPv6 addresses.
