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. Each VLAN may be assigned to a site and/or VLAN group.

Each VLAN must be assigned one of the following operational statuses:

  • Active
  • Reserved
  • Deprecated

Each VLAN may also be assigned a functional role. Prefixes and VLANs share the same set of customizable roles.

VLAN Groups

VLAN groups can be used to organize VLANs within NetBox. Groups can also be used to enforce uniqueness: 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 VLANs which belong to a common site). For example, you can create two VLANs with ID 123, but they cannot both be assigned to the same group.
