+# Change Logging
+
+Every time an object in NetBox is created, updated, or deleted, a serialized copy of that object is saved to the database, along with meta data including the current time and the user associated with the change. These records form a running changelog both for each individual object as well as NetBox as a whole (Organization > Changelog).
+
+A serialized representation is included for each object in JSON format. This is similar to how objects are conveyed within the REST API, but does not include any nested representations. For instance, the `tenant` field of a site will record only the tenant's ID, not a representation of the tenant.
+
+When a request is made, a random request ID is generated and attached to any change records resulting from the request. For example, editing multiple objects in bulk will create a change record for each object, and each of those objects will be assigned the same request ID. This makes it easy to identify all the change records associated with a particular request.
+
+Change records are exposed in the API via the read-only endpoint `/api/extras/object-changes/`. They may also be exported in CSV format.

+# Contextual Configuration Data
+
+Sometimes it is desirable to associate arbitrary data with a group of devices to aid in their configuration. For example, you might want to associate a set of syslog servers for all devices at a particular site. Context data enables the association of arbitrary data to devices and virtual machines grouped by region, site, role, platform, and/or tenant. Context data is arranged hierarchically, so that data with a higher weight can be entered to override more general lower-weight data. Multiple instances of data are automatically merged by NetBox to present a single dictionary for each object.

docs/additional-features/custom-fields.md

@@ -0,0 +1,26 @@
+# Custom Fields
+
+Each object in NetBox is represented in the database as a discrete table, and each attribute of an object exists as a column within its table. For example, sites are stored in the `dcim_site` table, which has columns named `name`, `facility`, `physical_address`, and so on. As new attributes are added to objects throughout the development of NetBox, tables are expanded to include new rows.
+
+However, some users might want to associate with objects attributes that are somewhat esoteric in nature, and that would not make sense to include in the core NetBox database schema. For instance, suppose your organization needs to associate each device with a ticket number pointing to the support ticket that was opened to have it installed. This is certainly a legitimate use for NetBox, but it's perhaps not a common enough need to warrant expanding the internal data schema. Instead, you can create a custom field to hold this data.
+
+Custom fields must be created through the admin UI under Extras > Custom Fields. To create a new custom field, select the object(s) to which you want it to apply, and the type of field it will be. NetBox supports six field types:
+
+* Free-form text (up to 255 characters)
+* Integer
+* Boolean (true/false)
+* Date
+* URL
+* Selection
+
+Assign the field a name. This should be a simple database-friendly string, e.g. `tps_report`. You may optionally assign the field a human-friendly label (e.g. "TPS report") as well; the label will be displayed on forms. If a description is provided, it will appear beneath the field in a form.
+
+Marking the field as required will require the user to provide a value for the field when creating a new object or when saving an existing object. A default value for the field may also be provided. Use "true" or "false" for boolean fields. (The default value has no effect for selection fields.)
+
+When creating a selection field, you should create at least two choices. These choices will be arranged first by weight, with lower weights appearing higher in the list, and then alphabetically.
+
+## Using Custom Fields
+
+When a single object is edited, the form will include any custom fields which have been defined for the object type. These fields are included in the "Custom Fields" panel. On the backend, each custom field value is saved separately from the core object as an independent database call, so it's best to avoid adding too many custom fields per object.
+
+When editing multiple objects, custom field values are saved in bulk. There is no significant difference in overhead when saving a custom field value for 100 objects versus one object. However, the bulk operation must be performed separately for each custom field.

+# Export Templates
+
+NetBox allows users to define custom templates that can be used when exporting objects. To create an export template, navigate to Extras > Export Templates under the admin interface.
+
+Each export template is associated with a certain type of object. For instance, if you create an export template for VLANs, your custom template will appear under the "Export" button on the VLANs list.
+
+Export templates are written in [Django's template language](https://docs.djangoproject.com/en/1.9/ref/templates/language/), which is very similar to Jinja2. The list of objects returned from the database is stored in the `queryset` variable, which you'll typically want to iterate through using a `for` loop. Object properties can be access by name. For example:
+
+```
+{% for rack in queryset %}
+Rack: {{ rack.name }}
+Site: {{ rack.site.name }}
+Height: {{ rack.u_height }}U
+{% endfor %}
+```
+
+To access custom fields of an object within a template, use the `cf` attribute. For example, `{{ obj.cf.color }}` will return the value (if any) for a custom field named `color` on `obj`.
+
+A MIME type and file extension can optionally be defined for each export template. The default MIME type is `text/plain`.
+
+## Example
+
+Here's an example device export template that will generate a simple Nagios configuration from a list of devices.
+
+```
+{% for device in queryset %}{% if device.status and device.primary_ip %}define host{
+        use                     generic-switch
+        host_name               {{ device.name }}
+        address                 {{ device.primary_ip.address.ip }}
+}
+{% endif %}{% endfor %}
+```
+
+The generated output will look something like this:
+
+```
+define host{
+        use                     generic-switch
+        host_name               switch1
+        address                 192.0.2.1
+}
+define host{
+        use                     generic-switch
+        host_name               switch2
+        address                 192.0.2.2
+}
+define host{
+        use                     generic-switch
+        host_name               switch3

+# Graphs
+
+NetBox does not have the ability to generate graphs natively, but this feature allows you to embed contextual graphs from an external resources (such as a monitoring system) inside the site, provider, and interface views. Each embedded graph must be defined with the following parameters:
+
+* **Type:** Site, provider, or interface. This determines in which view the graph will be displayed.
+* **Weight:** Determines the order in which graphs are displayed (lower weights are displayed first). Graphs with equal weights will be ordered alphabetically by name.
+* **Name:** The title to display above the graph.
+* **Source URL:** The source of the image to be embedded. The associated object will be available as a template variable named `obj`.
+* **Link URL (optional):** A URL to which the graph will be linked. The associated object will be available as a template variable named `obj`.
+
+## Examples
+
+You only need to define one graph object for each graph you want to include when viewing an object. For example, if you want to include a graph of traffic through an interface over the past five minutes, your graph source might looks like this:
+
+```
+https://my.nms.local/graphs/?node={{ obj.device.name }}&interface={{ obj.name }}&duration=5m
+```
+
+You can define several graphs to provide multiple contexts when viewing an object. For example:
+
+```
+https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=60m
+https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=24h

+# Tags
+
+Tags are free-form text labels which can be applied to a variety of objects within NetBox. Tags are created on-demand as they are assigned to objects. Use commas to separate tags when adding multiple tags to an object 9for example: `Inventoried, Monitored`). Use double quotes around a multi-word tag when adding only one tag, e.g. `"Core Switch"`.
+
+Each tag has a label and a URL-friendly slug. For example, the slug for a tag named "Dunder Mifflin, Inc." would be `dunder-mifflin-inc`. The slug is generated automatically and makes tags easier to work with as URL parameters.
+
+Objects can be filtered by the tags they have applied. For example, the following API request will retrieve all devices tagged as "monitored":
+
+```
+GET /api/dcim/devices/?tag=monitored
+```
+
+Tags are included in the API representation of an object as a list of plain strings:

+    "tags": [
+        "Core Switch",
+        "Monitored"

+# Topology Maps
+
+NetBox can generate simple topology maps from the physical network connections recorded in its database. First, you'll need to create a topology map definition under the admin UI at Extras > Topology Maps.
+
+Each topology map is associated with a site. A site can have multiple topology maps, which might each illustrate a different aspect of its infrastructure (for example, production versus backend infrastructure).
+
+To define the scope of a topology map, decide which devices you want to include. The map will only include interface connections with both points terminated on an included device. Specify the devices to include in the **device patterns** field by entering a list of [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) matching device names. For example, if you wanted to include "mgmt-switch1" through "mgmt-switch99", you might use the regex `mgmt-switch\d+`.
+
+Each line of the **device patterns** field represents a hierarchical layer within the topology map. For example, you might map a traditional network with core, distribution, and access tiers like this:
+
+```
+core-switch-[abcd]
+dist-switch\d
+access-switch\d+;oob-switch\d+
+```
+
+Note that you can combine multiple regexes onto one line using semicolons. The order in which regexes are listed on a line is significant: devices matching the first regex will be rendered first, and subsequent groups will be rendered to the right of those.

+# Webhooks
+
+A webhook defines an HTTP request that is sent to an external application when certain types of objects are created, updated, and/or deleted in NetBox. When a webhook is triggered, a POST request is sent to its configured URL. This request will include a full representation of the object being modified for consumption by the receiver. Webhooks are configured via the admin UI under Extras > Webhooks.
+
+An optional secret key can be configured for each webhook. This will append a `X-Hook-Signature` header to the request, consisting of a HMAC (SHA-512) hex digest of the request body using the secret as the key. This digest can be used by the receiver to authenticate the request's content.
+
+## Requests
+
+The webhook POST request is structured as so (assuming `application/json` as the Content-Type):
+
+```no-highlight
+{
+    "event": "created",
+    "signal_received_timestamp": 1508769597,
+    "model": "Site"
+    "data": {
+        ...
+    }
+}
+```
+
+`data` is the serialized representation of the model instance(s) from the event. The same serializers from the NetBox API are used. So an example of the payload for a Site delete event would be:
+
+```no-highlight
+{

+
+A request is considered successful if the response status code is any one of a list of "good" statuses defined in the [requests library](https://github.com/requests/requests/blob/205755834d34a8a6ecf2b0b5b2e9c3e6a7f4e4b6/requests/models.py#L688), otherwise the request is marked as having failed. The user may manually retry a failed request.

+# Replicating the Database
+
+NetBox uses [PostgreSQL](https://www.postgresql.org/) for its database, so general PostgreSQL best practices will apply to NetBox. You can dump and restore the database using the `pg_dump` and `psql` utilities, respectively.
+
+!!! note
+    The examples below assume that your database is named `netbox`.
+
+## Export the Database
+
+Use the `pg_dump` utility to export the entire database to a file:
+
+```no-highlight
+pg_dump netbox > netbox.sql
+```
+
+When replicating a production database for development purposes, you may find it convenient to exclude changelog data, which can easily account for the bulk of a database's size. To do this, exclude the `extras_objectchange` table data from the export. The table will still be included in the output file, but will not be populated with any data.
+
+```no-highlight
+pg_dump --exclude-table-data=extras_objectchange netbox > netbox.sql
+```
+
+## Load an Exported Database
+
+!!! warning
+    This will destroy and replace any existing instance of the database.
+
+```no-highlight
+psql -c 'drop database netbox'
+psql -c 'create database netbox'
+psql netbox < netbox.sql
+```
+
+Keep in mind that PostgreSQL user accounts and permissions are not included with the dump: You will need to create those manually if you want to fully replicate the original database (see the [installation docs](installation/1-postgresql.md)). When setting up a development instance of NetBox, it's strongly recommended to use different credentials anyway.
+
+## Export the Database Schema
+
+If you want to export only the database schema, and not the data itself (e.g. for development reference), do the following:
+
+```no-highlight
+pg_dump -s netbox > netbox_schema.sql
+```
+
+---
+
+# Replicating Media
+
+NetBox stored uploaded files (such as image attachments) in its media directory. To fully replicate an instance of NetBox, you'll need to copy both the database and the media files.
+
+## Archive the Media Directory
+
+Execute the following command from the root of the NetBox installation path (typically `/opt/netbox`):
+
+```no-highlight
+tar -czf netbox_media.tar.gz netbox/media/
+```

+# Device Types
+
+A device type represents a particular make and model of hardware that exists in the real world. Device types define the physical attributes of a device (rack height and depth) and its individual components (console, power, and network interfaces).
+
+Device types are instantiated as devices installed within racks. For example, you might define a device type to represent a Juniper EX4300-48T network switch with 48 Ethernet interfaces. You can then create multiple devices of this type named "switch1," "switch2," and so on. Each device will 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.)
+
+The device type model includes three flags which inform what type of components may be added to it:
+
+* `is_console_server`: This device type has console server ports
+* `is_pdu`: This device type has power outlets
+* `is_network_device`: This device type has network interfaces
+
+Some devices house child devices which share physical resources, like space and power, but which functional independently from one another. A common example of this is blade server chassis. Each device type is designated as one of the following:
+
+* A parent device (which has device bays)
+* A child device (which must be installed in a device bay)
+* Neither
+
+!!! note
+    This parent/child relationship is **not** suitable for modeling chassis-based devices, wherein child members share a common control plane.
+
+## Manufacturers
+
+Each device type must be assigned to a manufacturer. The model number of a device type must be unique to its manufacturer.
+
+## Component Templates
+
+Each device type is assigned a number of component templates which define the physical components within a device. These are:
+
+* Console ports
+* Console server ports
+* Power ports
+* Power outlets
+* Network interfaces
+* Device bays (which house child devices)
+
+Whenever a new device is created, its components are automatically created per the templates assigned to its device type. For example, a Juniper EX4300-48T device type might have the following component templates defined:
+
+* One template for a console port ("Console")
+* Two templates for power ports ("PSU0" and "PSU1")
+* 48 templates for 1GE interfaces ("ge-0/0/0" through "ge-0/0/47")
+* Four templates for 10GE interfaces ("xe-0/2/0" through "xe-0/2/3")
+
+Once component templates have been created, every new device that you create as an instance of this type will automatically be assigned each of the components listed above.
+
+!!! note
+    Assignment of components from templates occurs only at the time of device creation. If you modify the templates of a device type, it will not affect devices which have already been created. However, you always have the option of adding, modifying, or deleting components on existing devices.
+
+---
+
+# Devices
+
+Every piece of hardware which is installed within a rack exists in NetBox as a device. Devices are measured in rack units (U) and can be half depth or full depth. A device may have a height of 0U: These devices do not consume vertical rack space and cannot be assigned to a particular rack unit. A common example of a 0U device is a vertically-mounted PDU.
+
+When assigning a multi-U device to a rack, it is considered to be mounted in the lowest-numbered rack unit which it occupies. For example, a 3U device which occupies U8 through U10 is said to be mounted in U8. This logic applies to racks with both ascending and descending unit numbering.
+
+A device is said to be full depth if its installation on one rack face prevents the installation of any other device on the opposite face within the same rack unit(s). This could be either because the device is physically too deep to allow a device behind it, or because the installation of an opposing device would impede airflow.
+
+## Device Roles
+
+Devices can be organized by functional roles. These roles are fully cusomizable. For example, you might create roles for core switches, distribution switches, and access switches.
+
+---
+
+# Device Components
+
+There are six types of device components which comprise all of the interconnection logic with NetBox:
+
+* Console ports
+* Console server ports
+* Power ports
+* Power outlets
+* Network interfaces
+* Device bays
+
+## Console
+
+Console ports connect only to console server ports. Console connections can be marked as either *planned* or *connected*.
+
+## Power
+
+Power ports connect only to power outlets. Power connections can be marked as either *planned* or *connected*.
+
+## Interfaces
+
+Interfaces connect to one another in a symmetric manner: If interface A connects to interface B, interface B therefore connects to interface A. Each type of connection can be classified as either *planned* or *connected*.
+
+Each interface is a assigned a form factor denoting its physical properties. Two special form factors exist: the "virtual" form factor can be used to designate logical interfaces (such as SVIs), and the "LAG" form factor can be used to desinate link aggregation groups to which physical interfaces can be assigned.
+
+Each interface can also be enabled or disabled, and optionally designated as management-only (for out-of-band management). Fields are also provided to store an interface's MTU and MAC address.
+
+VLANs can be assigned to each interface as either tagged or untagged. (An interface may have only one untagged VLAN.)
+
+## Device Bays
+
+Device bays represent the ability of a device to house child devices. For example, you might install four blade servers into a 2U chassis. The chassis would appear in the rack elevation as a 2U device with four device bays. Each server within it would be defined as a 0U device installed in one of the device bays. Child devices do not appear within rack elevations, but they are included in the "Non-Racked Devices" list within the rack view.
+
+---
+
+# Platforms
+
+A platform defines the type of software running on a device or virtual machine. This can be helpful when it is necessary to distinguish between, for instance, different feature sets. Note that two devices of same type may be assigned different platforms: for example, one Juniper MX240 running Junos 14 and another running Junos 15.
+
+The platform model is also used to indicate which [NAPALM](https://napalm-automation.net/) driver NetBox should use when connecting to a remote device. The name of the driver along with optional parameters are stored with the platform. See the [API documentation](api/napalm-integration.md) for more information on NAPALM integration.
+
+The assignment of platforms to devices is an optional feature, and may be disregarded if not desired.
+
+---
+
+# Inventory Items
+
+Inventory items represent hardware components installed within a device, such as a power supply or CPU. Currently, these are used merely for inventory tracking, although future development might see their functionality expand. Like device types, each item can optionally be assigned a manufacturer.
+
+---
+
+# Virtual Chassis
+
+A virtual chassis represents a set of devices which share a single control plane: a stack of switches which are managed as a single device, for example. Each device in the virtual chassis is assigned a position and (optionally) a priority. Exactly one device is designated the virtual chassis master: This device will typically be assigned a name, secrets, services, and other attributes related to its management.
+
+It's important to recognize the distinction between a virtual chassis and a chassis-based device. For instance, a virtual chassis is not used to model a chassis switch with removable line cards such as the Juniper EX9208, as its line cards are _not_ physically separate devices capable of operating independently.

+# Aggregates
+
+The first step to documenting your IP space is to define its scope by creating aggregates. Aggregates establish the root of your IP address hierarchy by defining the top-level allocations that you're interested in managing. Most organizations will want to track some commonly-used private IP spaces, such as:
+
+* 10.0.0.0/8 (RFC 1918)
+* 100.64.0.0/10 (RFC 6598)
+* 172.16.0.0/20 (RFC 1918)
+* 192.168.0.0/16 (RFC 1918)
+* One or more /48s within fd00::/8 (IPv6 unique local addressing)
+
+In addition to one or more of these, you'll want to create an aggregate for each globally-routable space your organization has been allocated. These aggregates should match the allocations recorded in public WHOIS databases.
+
+Each IP prefix will be automatically arranged under its parent aggregate if one exists. Note that it's advised to create aggregates only for IP ranges actually allocated to your organization (or marked for private use): There is no need to define aggregates for provider-assigned space which is only used on Internet circuits, for example.
+
+Aggregates cannot overlap with one another: They can only exist side-by-side. For instance, you cannot define both 10.0.0.0/8 and 10.16.0.0/16 as aggregates, because they overlap. 10.16.0.0/16 in this example would be created as a prefix and automatically grouped under 10.0.0.0/8. Remember, the purpose of aggregates is to establish the root of your IP addressing hierarchy.
+
+## Regional Internet Registries (RIRs)
+
+[Regional Internet registries](https://en.wikipedia.org/wiki/Regional_Internet_registry) are responsible for the allocation of globally-routable address space. The five RIRs are ARIN, RIPE, APNIC, LACNIC, and AFRINIC. However, some address space has been set aside for internal use, such as defined in RFCs 1918 and 6598. NetBox considers these RFCs as a sort of RIR as well; that is, an authority which "owns" certain address space. There also exist lower-tier registries which serve a particular geographic area.
+
+Each aggregate must be assigned to one RIR. You are free to define whichever RIRs you choose (or create your own). The RIR model includes a boolean flag which indicates whether the RIR allocates only private IP space.
+
+For example, suppose your organization has been allocated 104.131.0.0/16 by ARIN. It also makes use of RFC 1918 addressing internally. You would first create RIRs named ARIN and RFC 1918, then create an aggregate for each of these top-level prefixes, assigning it to its respective RIR.
+
+---
+
+# Prefixes
+
+A prefix is an IPv4 or IPv6 network and mask expressed in CIDR notation (e.g. 192.0.2.0/24). A prefix entails only the "network portion" of an IP address: All bits in the address not covered by the mask must be zero. (In other words, a prefix cannot be a specific IP address.)
+
+Prefixes are automatically arranged by their parent aggregates. Additionally, each prefix can be assigned to a particular site and VRF (routing table). All prefixes not assigned to a VRF will appear in the "global" table.
+
+Each prefix can be assigned a status and a role. These terms are often used interchangeably so it's important to recognize the difference between them. The **status** defines a prefix's operational state. Statuses are hard-coded in NetBox and can be one of the following:
+
+* Container - A summary of child prefixes
+* Active - Provisioned and in use
+* Reserved - Designated for future use
+* Deprecated - No longer in use
+
+On the other hand, a prefix's **role** defines its function. Role assignment is optional and roles are fully customizable. For example, you might create roles to differentiate between production and development infrastructure.
+
+A prefix may also be assigned to a VLAN. This association is helpful for identifying which prefixes are included when reviewing a list of VLANs.
+
+The prefix model include a "pool" flag. If enabled, NetBox will treat this prefix as a range (such as a NAT pool) wherein every IP address is valid and assignable. This logic is used for identifying available IP addresses within a prefix. If this flag is disabled, NetBox will assume that the first and last (broadcast) address within the prefix are unusable.
+
+---
+
+# IP Addresses
+
+An IP address comprises a single host address (either IPv4 or IPv6) and its subnet mask. Its mask should match exactly how the IP address is configured on an interface in the real world.
+
+Like prefixes, an IP address can optionally be assigned to a VRF (otherwise, it will appear in the "global" table). IP addresses are automatically organized under parent prefixes within their respective VRFs.
+
+Also like prefixes, each IP address can be assigned a status and a role. Statuses are hard-coded in NetBox and include the following:
+
+* Active
+* Reserved
+* Deprecated
+* DHCP
+
+Each IP address can optionally be assigned a special role. Roles are used to indicate some special attribute of an IP address: for example, it is used as a loopback, or is a virtual IP maintained using VRRP. (Note that this differs in purpose from a _functional_ role, and thus cannot be customized.) Available roles include:
+
+* Loopback
+* Secondary
+* Anycast
+* VIP
+* VRRP
+* HSRP
+* GLBP
+
+An IP address can be assigned to a device or virtual machine interface, and an interface may have multiple IP addresses assigned to it. Further, each device and virtual machine may have one of its interface IPs designated as its primary IP address (one for IPv4 and one for IPv6).
+
+## Network Address Translation (NAT)
+
+An IP address can be designated as the network address translation (NAT) inside IP address for exactly one other IP address. This is useful primarily to denote a translation between public and private IP addresses. This relationship is followed in both directions: For example, if 10.0.0.1 is assigned as the inside IP for 192.0.2.1, 192.0.2.1 will be displayed as the outside IP for 10.0.0.1.
+
+!!! note
+    NetBox does not support tracking one-to-many NAT relationships (also called port address translation). This type of policy requires additional logic to model and cannot be fully represented by IP address alone.
+
+---
+
+# Virtual Routing and Forwarding (VRF)
+
+A VRF object in NetBox represents a virtual routing and forwarding (VRF) domain. Each VRF is essentially a separate routing table. VRFs are commonly used to isolate customers or organizations from one another within a network, or to route overlapping address space (e.g. multiple instances of the 10.0.0.0/8 space).
+
+Each VRF is assigned a unique name and route distinguisher (RD). The RD is expected to take one of the forms prescribed in [RFC 4364](https://tools.ietf.org/html/rfc4364#section-4.2), however its formatting is not strictly enforced.
+
+Each prefix and IP address may be assigned to one (and only one) VRF. If you have a prefix or IP address which exists in multiple VRFs, you will need to create a separate instance of it in NetBox for each VRF. Any IP prefix or address not assigned to a VRF is said to belong to the "global" table.
+
+By default, NetBox will allow duplicate prefixes to be assigned to a VRF. This behavior can be disabled by setting the "enforce unique" flag on the VRF model.
+
+!!! note
+    Enforcement of unique IP space can be toggled for global table (non-VRF prefixes) using the `ENFORCE_GLOBAL_UNIQUE` configuration setting.

+
+The site model also includes several fields for storing contact and address information.
+
+## Regions
+
+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.

+# Racks
+
+The rack model represents a physical two- or four-post equipment rack in which equipment is mounted. Each rack must be assigned to a site. 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 or descending order.
+
+Each rack is assigned a name and (optionally) a separate facility ID. This is helpful when leasing space in a data center your organization does not own: The facility will often assign a seemingly arbitrary ID to a rack (for example, "M204.313") whereas internally you refer to is simply as "R113." A unique serial number may also be associated with each rack.

+A rack must be designated as one of the following types:
+
+* 2-post frame
+* 4-post frame
+* 4-post cabinet
+* Wall-mounted frame
+* Wall-mounted cabinet
+
+Each rack has two faces (front and rear) on which devices can be mounted. Rail-to-rail width may be 19 or 23 inches.
+
+## Rack Groups
+
+Racks can be arranged into groups. As with sites, how you choose to designate rack groups will depend on the nature of your organization. For example, if each site represents a campus, each group might represent a building within a campus. If each site represents a building, each rack group might equate to a floor or room.
+
+Each rack group must be assigned to a parent site. Hierarchical recursion of rack groups is not currently supported.

-Racks can be arranged into groups. As with sites, how you choose to designate rack groups will depend on the nature of your organization. For example, if each site represents a campus, each group might represent a building within a campus. If each site represents a building, each rack group might equate to a floor or room.
-
-Each group is assigned to a parent site for easy navigation. Hierarchical recursion of rack groups is not supported.
-
-### Rack Roles
-
-Each rack can optionally be assigned a functional role. For example, you might designate a rack for compute or storage resources, or to house colocated customer devices. Rack roles are fully customizable.
-
-### Rack Space Reservations
-
-Users can reserve units within a rack for future use. Multiple non-contiguous rack units can be associated with a single reservation (but reservations cannot span multiple racks).
-

-# Device Types
-
-A device type represents a particular hardware model that exists in the real world. Device types describe the physical attributes of a device (rack height and depth), its class (e.g. console server, PDU, etc.), and its individual components (console, power, and data).
-
-Device types are instantiated as devices installed within racks. For example, you might define a device type to represent a Juniper EX4300-48T network switch with 48 Ethernet interfaces. You can then create multiple devices of this type named "switch1," "switch2," and so on. Each device will inherit the components (such as interfaces) of its device type.
-
-A device type can be a parent, child, or neither. Parent devices house child devices in device bays. This relationship is used to model things like blade servers, where child devices function independently but share physical resources like rack space and power. Note that this is **not** intended to model chassis-based devices, wherein child members share a common control plane.
-
-### Manufacturers
-
-Each device type belongs to one manufacturer; e.g. Cisco, Opengear, or APC. The model number of a device type must be unique to its manufacturer.
-
-### Component Templates
-
-Each device type is assigned a number of component templates which define the physical interfaces a device has. These are:
-
-* Console ports
-* Console server ports
-* Power ports
-* Power outlets
-* Interfaces
-* Device bays
-
-Whenever a new device is created, it is automatically assigned components per the templates assigned to its device type. For example, a Juniper EX4300-48T device type might have the following component templates:
-
-* One template for a console port ("Console")
-* Two templates for power ports ("PSU0" and "PSU1")
-* 48 templates for 1GE interfaces ("ge-0/0/0" through "ge-0/0/47")
-* Four templates for 10GE interfaces ("xe-0/2/0" through "xe-0/2/3")
-
-Once component templates have been created, every new device that you create as an instance of this type will automatically be assigned each of the components listed above.
-
-!!! note
-    Assignment of components from templates occurs only at the time of device creation. If you modify the templates of a device type, it will not affect devices which have already been created. However, you always have the option of adding, modifying, or deleting components of existing devices individually.
-
----
-
-# Devices
-
-Every piece of hardware which is installed within a rack exists in NetBox as a device. Devices are measured in rack units (U) and depth. 0U devices which can be installed in a rack but don't consume vertical rack space (such as a vertically-mounted power distribution unit) can also be defined.
-
-When assigning a multi-U device to a rack, it is considered to be mounted in the lowest-numbered rack unit which it occupies. For example, a 3U device which occupies U8 through U10 shows as being mounted in U8. This logic applies to racks with both ascending and descending unit numbering.
-
-A device is said to be "full depth" if its installation on one rack face prevents the installation of any other device on the opposite face within the same rack unit(s). This could be either because the device is physically too deep to allow a device behind it, or because the installation of an opposing device would impede air flow.
-
-### Roles
-
-NetBox allows for the definition of arbitrary device roles by which devices can be organized. For example, you might create roles for core switches, distribution switches, and access switches. In the interest of simplicity, a device can belong to only one role.
-
-### Platforms
-
-A device's platform is used to denote the type of software running on it. This can be helpful when it is necessary to distinguish between, for instance, different feature sets. Note that two devices of same type may be assigned different platforms: for example, one Juniper MX240 running Junos 14 and another running Junos 15.
-
-The assignment of platforms to devices is an optional feature, and may be disregarded if not desired.
-
-### Inventory Items
-
-Inventory items represent hardware components installed within a device, such as a power supply or CPU. Currently, these are used merely for inventory tracking, although future development might see their functionality expand. Each item can optionally be assigned a manufacturer.
-
-!!! note
-    Prior to version 2.0, inventory items were called modules.
-
-### Components
-
-There are six types of device components which comprise all of the interconnection logic with NetBox:
-
-* Console ports
-* Console server ports
-* Power ports
-* Power outlets
-* Interfaces
-* Device bays
-
-Console ports connect only to console server ports, and power ports connect only to power outlets. Interfaces connect to one another in a symmetric manner: If interface A connects to interface B, interface B therefore connects to interface A. (The relationship between two interfaces is actually represented in the database by an InterfaceConnection object, but this is transparent to the user.) Each type of connection can be classified as either *planned* or *connected*. This allows for easily denoting connections which have not yet been installed.
-
-Each interface is a assigned a form factor denoting its physical properties. Two special form factors exist: the "virtual" form factor can be used to designate logical interfaces (such as SVIs), and the "LAG" form factor can be used to desinate link aggregation groups to which physical interfaces can be assigned. Each interface can also be designated as management-only (for out-of-band management) and assigned a short description.
-
-Device bays represent the ability of a device to house child devices. For example, you might install four blade servers into a 2U chassis. The chassis would appear in the rack elevation as a 2U device with four device bays. Each server within it would be defined as a 0U device installed in one of the device bays. Child devices do not appear on rack elevations, but they are included in the "Non-Racked Devices" list within the rack view.
-
----
-
-# Virtual Chassis
-
-A virtual chassis represents a set of devices which share a single control plane: for example, a stack of switches which are managed as a single device. Each device in the virtual chassis is assigned a position and (optionally) a priority. Exactly one device is designated the virtual chassis master: This device will typically be assigned a name, secrets, services, and other attributes related to its management.
-
-It's important to recognize the distinction between a virtual chassis and a chassis-based device. For instance, a virtual chassis is not used to model a chassis switch with removable line cards such as the Juniper EX9208, as its line cards are _not_ physically separate devices capable of operating independently.

-This section entails features of NetBox which are not crucial to its primary functions, but provide additional value.
-
-# Custom Fields
-
-Each object in NetBox is represented in the database as a discrete table, and each attribute of an object exists as a column within its table. For example, sites are stored in the `dcim_site` table, which has columns named `name`, `facility`, `physical_address`, and so on. As new attributes are added to objects throughout the development of NetBox, tables are expanded to include new rows.
-
-However, some users might want to associate with objects attributes that are somewhat esoteric in nature, and that would not make sense to include in the core NetBox database schema. For instance, suppose your organization needs to associate each device with a ticket number pointing to the support ticket that was opened to have it installed. This is certainly a legitimate use for NetBox, but it's perhaps not a common enough need to warrant expanding the internal data schema. Instead, you can create a custom field to hold this data.
-
-Custom fields must be created through the admin UI under Extras > Custom Fields. To create a new custom field, select the object(s) to which you want it to apply, and the type of field it will be. NetBox supports six field types:
-
-* Free-form text (up to 255 characters)
-* Integer
-* Boolean (true/false)
-* Date
-* URL
-* Selection
-
-Assign the field a name. This should be a simple database-friendly string, e.g. `tps_report`. You may optionally assign the field a human-friendly label (e.g. "TPS report") as well; the label will be displayed on forms. If a description is provided, it will appear beneath the field in a form.
-
-Marking the field as required will require the user to provide a value for the field when creating a new object or when saving an existing object. A default value for the field may also be provided. Use "true" or "false" for boolean fields. (The default value has no effect for selection fields.)
-
-When creating a selection field, you should create at least two choices. These choices will be arranged first by weight, with lower weights appearing higher in the list, and then alphabetically.
-
-## Using Custom Fields
-
-When a single object is edited, the form will include any custom fields which have been defined for the object type. These fields are included in the "Custom Fields" panel. On the backend, each custom field value is saved separately from the core object as an independent database call, so it's best to avoid adding too many custom fields per object.
-
-When editing multiple objects, custom field values are saved in bulk. There is no significant difference in overhead when saving a custom field value for 100 objects versus one object. However, the bulk operation must be performed separately for each custom field.
-
-# Export Templates
-
-NetBox allows users to define custom templates that can be used when exporting objects. To create an export template, navigate to Extras > Export Templates under the admin interface.
-
-Each export template is associated with a certain type of object. For instance, if you create an export template for VLANs, your custom template will appear under the "Export" button on the VLANs list.
-
-Export templates are written in [Django's template language](https://docs.djangoproject.com/en/1.9/ref/templates/language/), which is very similar to Jinja2. The list of objects returned from the database is stored in the `queryset` variable, which you'll typically want to iterate through using a `for` loop. Object properties can be access by name. For example:
-
-```
-{% for rack in queryset %}
-Rack: {{ rack.name }}
-Site: {{ rack.site.name }}
-Height: {{ rack.u_height }}U
-{% endfor %}
-```
-
-To access custom fields of an object within a template, use the `cf` attribute. For example, `{{ obj.cf.color }}` will return the value (if any) for a custom field named `color` on `obj`.
-
-A MIME type and file extension can optionally be defined for each export template. The default MIME type is `text/plain`.
-
-## Example
-
-Here's an example device export template that will generate a simple Nagios configuration from a list of devices.
-
-```
-{% for device in queryset %}{% if device.status and device.primary_ip %}define host{
-        use                     generic-switch
-        host_name               {{ device.name }}
-        address                 {{ device.primary_ip.address.ip }}
-}
-{% endif %}{% endfor %}
-```
-
-The generated output will look something like this:
-
-```
-define host{
-        use                     generic-switch
-        host_name               switch1
-        address                 192.0.2.1
-}
-define host{
-        use                     generic-switch
-        host_name               switch2
-        address                 192.0.2.2
-}
-define host{
-        use                     generic-switch
-        host_name               switch3
-        address                 192.0.2.3
-}
-```
-
-# Graphs
-
-NetBox does not have the ability to generate graphs natively, but this feature allows you to embed contextual graphs from an external resources (such as a monitoring system) inside the site, provider, and interface views. Each embedded graph must be defined with the following parameters:
-
-* **Type:** Site, provider, or interface. This determines in which view the graph will be displayed.
-* **Weight:** Determines the order in which graphs are displayed (lower weights are displayed first). Graphs with equal weights will be ordered alphabetically by name.
-* **Name:** The title to display above the graph.
-* **Source URL:** The source of the image to be embedded. The associated object will be available as a template variable named `obj`.
-* **Link URL (optional):** A URL to which the graph will be linked. The associated object will be available as a template variable named `obj`.
-
-## Examples
-
-You only need to define one graph object for each graph you want to include when viewing an object. For example, if you want to include a graph of traffic through an interface over the past five minutes, your graph source might looks like this:
-
-```
-https://my.nms.local/graphs/?node={{ obj.device.name }}&interface={{ obj.name }}&duration=5m
-```
-
-You can define several graphs to provide multiple contexts when viewing an object. For example:
-
-```
-https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=60m
-https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=24h
-https://my.nms.local/graphs/?type=errors&node={{ obj.device.name }}&interface={{ obj.name }}&duration=60m
-```
-
-# Topology Maps
-
-NetBox can generate simple topology maps from the physical network connections recorded in its database. First, you'll need to create a topology map definition under the admin UI at Extras > Topology Maps.
-
-Each topology map is associated with a site. A site can have multiple topology maps, which might each illustrate a different aspect of its infrastructure (for example, production versus backend infrastructure).
-
-To define the scope of a topology map, decide which devices you want to include. The map will only include interface connections with both points terminated on an included device. Specify the devices to include in the **device patterns** field by entering a list of [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) matching device names. For example, if you wanted to include "mgmt-switch1" through "mgmt-switch99", you might use the regex `mgmt-switch\d+`.
-
-Each line of the **device patterns** field represents a hierarchical layer within the topology map. For example, you might map a traditional network with core, distribution, and access tiers like this:
-
-```
-core-switch-[abcd]
-dist-switch\d
-access-switch\d+;oob-switch\d+
-```
-
-Note that you can combine multiple regexes onto one line using semicolons. The order in which regexes are listed on a line is significant: devices matching the first regex will be rendered first, and subsequent groups will be rendered to the right of those.
-
-# Image Attachments
-
-Certain objects within NetBox (namely sites, racks, and devices) can have photos or other images attached to them. (Note that _only_ image files are supported.) Each attachment may optionally be assigned a name; if omitted, the attachment will be represented by its file name.
-
-!!! note
-    If you experience a server error while attempting to upload an image attachment, verify that the system user NetBox runs as has write permission to the media root directory (`netbox/media/`).

-IP address management (IPAM) entails the allocation of IP networks, addresses, and related numeric resources.
-
-# VRFs
-
-A VRF object in NetBox represents a virtual routing and forwarding (VRF) domain within a network. Each VRF is essentially a separate routing table: the same IP prefix or address can exist in multiple VRFs. VRFs are commonly used to isolate customers or organizations from one another within a network.
-
-Each VRF is assigned a name and a unique route distinguisher (RD). VRFs are an optional feature of NetBox: Any IP prefix or address not assigned to a VRF is said to belong to the "global" table.
-
-!!! note
-    By default, NetBox allows for overlapping IP space both in the global table and within each VRF. Unique space enforcement can be toggled per-VRF as well as in the global table using the `ENFORCE_GLOBAL_UNIQUE` configuration setting.
-
----
-
-# Aggregates
-
-IP address space is organized as a hierarchy, with more-specific (smaller) prefixes arranged as child nodes under less-specific (larger) prefixes. For example:
-
-* 10.0.0.0/8
-    * 10.1.0.0/16
-        * 10.1.2.0/24
-
-The root of the IPv4 hierarchy is 0.0.0.0/0, which encompasses all possible IPv4 addresses (and similarly, ::/0 for IPv6). However, even the largest organizations use only a small fraction of the global address space. Therefore, it makes sense to track in NetBox only the address space which is of interest to your organization.
-
-Aggregates serve as arbitrary top-level nodes in the IP space hierarchy. They allow you to easily construct your IP scheme without any clutter of unused address space. For instance, most organizations utilize some portion of the private IPv4 space set aside in RFC 1918. So, you might define three aggregates for this space:
-
-* 10.0.0.0/8
-* 172.16.0.0/12
-* 192.168.0.0/16
-
-Additionally, you might define an aggregate for each large swath of public IPv4 space your organization uses. You'd also create aggregates for both globally routable and unique local IPv6 space. (Most organizations will not have a need to track IPv6 link local space.)
-
-Prefixes you create in NetBox (discussed below) will be automatically organized under their respective aggregates. Any space within an aggregate which is not covered by an existing prefix will be annotated as available for allocation. Total utilization for each aggregate is displayed in the aggregates list.
-
-Aggregates cannot overlap with one another; they can only exist in parallel. For instance, you cannot define both 10.0.0.0/8 and 10.16.0.0/16 as aggregates, because they overlap. 10.16.0.0/16 in this example would be created as a prefix and automatically grouped under 10.0.0.0/8.
-
-### RIRs
-
-Regional Internet Registries (RIRs) are responsible for the allocation of global address space. The five RIRs are ARIN, RIPE, APNIC, LACNIC, and AFRINIC. However, some address space has been set aside for private or internal use only, such as defined in RFCs 1918 and 6598. NetBox considers these RFCs as a sort of RIR as well; that is, an authority which "owns" certain address space.
-
-Each aggregate must be assigned to one RIR. You are free to define whichever RIRs you choose (or create your own). Each RIR can be annotated as representing only private space.
-
----
-
-# Prefixes
-
-A prefix is an IPv4 or IPv6 network and mask expressed in CIDR notation (e.g. 192.0.2.0/24). A prefix entails only the "network portion" of an IP address; all bits in the address not covered by the mask must be zero.
-
-Each prefix may be assigned to one VRF; prefixes not assigned to a VRF are assigned to the "global" table. Prefixes are also organized under their respective aggregates, irrespective of VRF assignment.
-
-A prefix may optionally be assigned to one VLAN; a VLAN may have multiple prefixes assigned to it. Each prefix may also be assigned a short description.
-
-### Statuses
-
-Each prefix is assigned an operational status. This is one of the following:
-
-* Container - A summary of child prefixes
-* Active - Provisioned and in use
-* Reserved - Designated for future use
-* Deprecated - No longer in use
-
-### Roles
-
-Whereas a status describes a prefix's operational state, a role describes its function. For example, roles might include:
-
-* Access segment
-* Infrastructure
-* NAT
-* Lab
-* Out-of-band
-
-Role assignment is optional and roles are fully customizable.
-
----
-
-# IP Addresses
-
-An IP address comprises a single address (either IPv4 or IPv6) and its subnet mask. Its mask should match exactly how the IP address is configured on an interface in the real world.
-
-Like prefixes, an IP address can optionally be assigned to a VRF (or it will appear in the "global" table). IP addresses are automatically organized under parent prefixes within their respective VRFs. Each IP address can also be assigned a short description.
-
-An IP address can be assigned to a device's interface; an interface may have multiple IP addresses assigned to it. Further, each device may have one of its interface IPs designated as its primary IP address (for both IPv4 and IPv6).
-
-One IP address can be designated as the network address translation (NAT) IP address for exactly one other IP address. This is useful primarily to denote the public address for a private internal IP. Tracking one-to-many NAT (or PAT) assignments is not supported.
-
----
-
-# VLANs
-
-A VLAN represents an isolated layer two domain, identified by a name and a numeric ID (1-4094) as defined in [IEEE 802.1Q](https://en.wikipedia.org/wiki/IEEE_802.1Q). Each VLAN may be assigned to a site and/or VLAN group. Like prefixes, each VLAN is assigned an operational status and (optionally) a functional role, and may include a short description.
-
-### VLAN Groups
-
-VLAN groups can be employed for administrative organization within NetBox. Each VLAN within a group must have a unique ID and name. VLANs which are not assigned to a group may have overlapping names and IDs, including within a site.
-
----
-
-# Services
-
-A service represents a TCP or UDP service available on a device or virtual machine. Each service must be defined with a name, protocol, and port number; for example, "SSH (TCP/22)." A service may optionally be bound to one or more specific IP addresses belonging to its parent. (If no IP addresses are bound, the service is assumed to be reachable via any assigned IP address.)

-NetBox supports the definition of virtual machines arranged in clusters. A cluster can optionally have physical host devices associated with it.
-
-# Clusters
-
-A cluster is a logical grouping of physical resources within which virtual machines run. A cluster must be assigned a type, and may optionally be assigned an organizational group.
-
-Physical devices (from NetBox's DCIM component) may be associated with clusters as hosts. This allows users to track on which host(s) a particular VM may reside. However, NetBox does not support pinning a specific VM within a cluster to a particular host device.
-
-### Cluster Types
-
-A cluster type represents a technology or mechanism by which a cluster is formed. For example, you might create a cluster type named "VMware vSphere" for a locally hosted cluster or "DigitalOcean NYC3" for one hosted by a cloud provider.

These behave similarly to device interfaces, and can be assigned IP addresses, however given their virtual nature they cannot be connected to other interfaces. VMs can also be assigned layer four services. Unlike physical devices, VMs cannot be assigned console or power ports, or device bays.

+# NetBox Development
+
+NetBox is maintained as a [GitHub project](https://github.com/digitalocean/netbox) under the Apache 2 license. Users are encouraged to submit GitHub issues for feature requests and bug reports, however we are very selective about pull requests. Please see the `CONTRIBUTING` guide for more direction on contributing to NetBox.
+
+## Communication
+
+Communication among developers should always occur via public channels:
+
+* [GitHub issues](https://github.com/digitalocean/netbox/issues) - All feature requests, bug reports, and other substantial changes to the code base **must** be documented in an issue.
+* [The mailing list](https://groups.google.com/forum/#!forum/netbox-discuss) - The preferred forum for general discussion and support issues. Ideal for shaping a feature request prior to submitting an issue.
+* [#netbox on NetworkToCode](http://slack.networktocode.com/) - Good for quick chats. Avoid any discussion that might need to be referenced later on, as the chat history is not retained long.
+
+## Governance
+
+NetBox follows the [benevolent dictator](http://oss-watch.ac.uk/resources/benevolentdictatorgovernancemodel) model of governance, with [Jeremy Stretch](https://github.com/jeremystretch) ultimately responsible for all changes to the code base. While community contributions are welcomed and encouraged, the lead maintainer's primary role is to ensure the project's long-term maintainability and continued focus on its primary functions (in other words, avoid scope creep).
+
+## Project Structure
+
+All development of the current NetBox release occurs in the `develop` branch; releases are packaged from the `master` branch. The `master` branch should _always_ represent the current stable release in its entirety, such that installing NetBox by either downloading a packaged release or cloning the `master` branch provides the same code base.
+
+NetBox components are arranged into functional subsections called _apps_ (a carryover from Django verancular). Each app holds the models, views, and templates relevant to a particular function:
+
+* `circuits`: Communications circuits and providers (not to be confused with power circuits)
+* `dcim`: Datacenter infrastructure management (sites, racks, and devices)
+* `extras`: Additional features not considered part of the core data model
+* `ipam`: IP address management (VRFs, prefixes, IP addresses, and VLANs)
+* `secrets`: Encrypted storage of sensitive data (e.g. login credentials)
+* `tenancy`: Tenants (such as customers) to which NetBox objects may be assigned
+* `utilities`: Resources which are not user-facing (extendable classes, etc.)
+* `virtualization`: Virtual machines and clusters
+
+## Style Guide
+
+NetBox generally follows the [Django style guide](https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/coding-style/), which is itself based on [PEP 8](https://www.python.org/dev/peps/pep-0008/). The following exceptions are noted:
+
+* [Pycodestyle](https://github.com/pycqa/pycodestyle) is used to validate code formatting, ignoring certain violations. See `scripts/cibuild.sh`.
+* Constants may be imported via wildcard (for example, `from .constants import *`).

+# Minor Version Bumps
+
+## Update Requirements
+
+Required Python packages are maintained in two files. `base_requirements.txt` contains a list of all the packages required by NetBox. Some of them may be pinned to a specific version of the package due to a known issue. For example:
+
+```
+# https://github.com/encode/django-rest-framework/issues/6053
+djangorestframework==3.8.1
+```
+
+The other file is `requirements.txt`, which lists each of the required packages pinned to its current stable version. When NetBox is installed, the Python environment is configured to match this file. This helps ensure that a new release of a dependency doesn't break NetBox.
+
+Every minor version release should refresh `requirements.txt` so that it lists the most recent stable release of each package. To do this:
+
+1. Create a new virtual environment.
+2. Install the latest version of all required packages via pip:
+
+```
+pip install -U -r base_requirements.txt
+```
+
+3. Run all tests and check that the UI and API function as expected.
+4. Update the package versions in `requirements.txt` as appropriate.
+
+## Update Static Libraries
+
+Update the following static libraries to their most recent stable release:
+
+* Bootstrap 3
+* Font Awesome 4
+* jQuery
+* jQuery UI
+
+## Manually Perform a New Install

 # What is NetBox?
 
 NetBox is an open source web application designed to help manage and document computer networks. Initially conceived by the network engineering team at [DigitalOcean](https://www.digitalocean.com/), NetBox was developed specifically to address the needs of network and infrastructure engineers.

 While NetBox strives to cover many areas of network management, the scope of its feature set is necessarily limited. This ensures that development focuses on core functionality and that scope creep is reasonably contained. To that end, it might help to provide some examples of functionality that NetBox **does not** provide:
