VNI Pools

VNI Pool Overview

You can create resource pools during the design phase or just before you need them during the build phase. When you assign resources to managed devices in your network (blueprint), they are pulled automatically from the pool you specify. In cases where you need to assign a specific network identifier you have the option of assigning a resource individually. To prevent shortages as a network grows, network design best practices recommend defining more resources than are required for the initial design.

Virtual network identifiers (VNIs) are VXLAN network identifiers used in a VXLAN-Aware datacenter fabrics. For more information about VNI usage, see Create Inter-rack VXLAN/EVPN based Virtual Networks. VNI pools include the following details:

Pool Name
To identify the resource pool.
Total Usage
Percentage of VNIs in use for all ranges in the resource pool. (Hover over status bar to see number of VNIs in use and total number of VNIs in the pool.) (New in version 3.3.0)
Range Usage
The VNIs included in the range and the percentage that are in use. (Hover over status bar to see number of VNIs in use and total number of VNIs in that range.) (New in version 3.3.0)
Status
Indicates if the pool is in use or not.
Tags (optional)
To enable filtering by user-specified categories.

From the web interface, navigate to Resources > VNI Pools.

    • To specify an additional range, click Add a range.
  3. Click Create to create the pool and return to the list view.

When the blueprint is ready, you can assign resources by updating assignments in the Staged > Physical view.

    • To remove a range, click the X to the right of the range to delete.
  3. Click Update to update the pool and return to the list view.

Deleting VNI Pool

If any VNIs in a VNI pool are in use, the pool cannot be deleted.
