Every piece of hardware which is installed within a site or 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.
Each device must be instantiated from a pre-created device type, and its default components (console ports, power ports, interfaces, etc.) will be created automatically. (The device type associated with a device may be changed after its creation, however its components will not be updated retroactively.)
Device names must be unique within a site, unless the device has been assigned to a tenant. Devices may also be unnamed.
When a device has one or more interfaces with IP addresses assigned, a primary IP for the device can be designated, for both IPv4 and IPv6.
Fields¶
Name¶
The device's configured name. This field is optional; devices can be unnamed. However, if set, the name must be unique to the assigned site and tenant.
Device Role¶
The functional role assigned to this device.
Device Type¶
The hardware device type which defines the device's make & model. Upon creating, all templated components assigned to the device type will be replicated on the new device.
Airflow¶
The direction in which air circulates through the device chassis for cooling.
Serial Number¶
The unique physical serial number assigned to this device by its manufacturer.
Asset Tag¶
A unique, locally-administered label used to identify hardware resources.
Site¶
The site in which this device is located.
Location¶
A specific location where this device resides within the assigned site (optional).
Rack¶
The rack within which this device is installed (optional).
Rack Face¶
If installed in a rack, this field denotes the primary face on which the device is mounted.
Position¶
If installed in a rack, this field indicates the base rack unit in which the device is mounted.
Tip
Devices with a height of more than one rack unit should be set to the lowest-numbered rack unit that they occupy.
Status¶
The device's operational status.
Tip
Additional statuses may be defined by setting Device.status under the FIELD_CHOICES configuration parameter.
Platform¶
A device may be associated with a particular platform to indicate its operating system. Note that only platforms assigned to the associated manufacturer (or to no manufacturer) will be available for selection.
Primary IPv4 & IPv6 Addresses¶
Each device may designate one primary IPv4 address and/or one primary IPv6 address for management purposes.
Tip
NetBox will prefer IPv6 addresses over IPv4 addresses by default. This can be changed by setting the PREFER_IPV4 configuration parameter.
Cluster¶
If this device will serve as a host for a virtualization cluster, it can be assigned here. (Host devices can also be assigned by editing the cluster.)
Virtual Chassis¶
The virtual chassis of which this device is a member, if any.
VC Position¶
If assigned to a virtual chassis, this field indicates the device's member position.
VC Priority¶
If assigned to a virtual chassis, this field indicates the device's priority for master election.
Local Config Context Data¶
Any unique context data to be associated with the device.
