 # 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.
+
+Devices and Virtual Machines may also have a local config context defined. This local context will always overwrite the rendered config context objects for the Device/VM. This is useful in situations were the device requires a one-off value different from the rest of the environment.

+Pass-through ports are used to model physical terminations which comprise part of a longer path, such as a cable terminated to a patch panel. Each front port maps to a position on a rear port. A 24-port UTP patch panel, for instance, would have 24 front ports and 24 rear ports. Although this relationship is typically one-to-one, a rear port may have multiple front ports mapped to it. This can be useful for modeling instances where multiple paths share a common cable (for example, six different fiber connections sharing a 12-strand MPO cable).

 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.

 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.

 It's important to recognize the distinction between a virtual chassis and a chassis-based device.
