VNI Pools (Resources)

VNI Pool Overview

Virtual network identifiers (VNIs) are used in VXLAN encapsulation to provide Layer 2 separation for the overlay traffic in your data center fabric. (For more information about VNI usage, see Virtual Networks. When you're building your blueprint you'll specify which resource pool to use for assigning VNIs.

Note: If you need to assign a specific VNI to a specific device, you can assign the VNI individually from the staged blueprint in the Properties panel of a selection.

VNI pools include the following details:

Name Description
Pool Name A unique name to identify the resource pool
Total Usage Percentage of VNIs in use for all ranges in the resource pool. (Hover over the status bar to see the number of VNIs in use and the total number of VNIs in the pool.)
Range Usage The VNIs included in the range and the percentage that are in use. (Hover over the status bar to see the number of VNIs in use and the total number of VNIs in that range.)
Status Indicates if the pool is in use

From the left navigation menu, navigate to Resources > VNI Pools to go to VNI pools in the design (global) catalog. You can create, clone, edit and delete VNI pools.

Create VNI Pool

  1. From the left navigation menu, navigate to Resources > VNI Pools and click Create VNI Pool.
  2. Enter a unique name and a valid range (4096 through 16777214). To add another range, click Add a range and enter the range.
  3. Click Create to create the pool and return to the table view.

When you've created your blueprint, you'll assign resources from these pools in the Staged > Virtual view of the blueprint.

Edit VNI Pool

  1. Either from the table view (Resources > VNI Pools) or the details view, click the Edit button for the pool to edit.
  2. Make your changes. You can add, change, and delete ranges, but you cannot remove any VNIs that are in use.
  3. Click Update to update the pool and return to the table view.

Delete VNI Pool

You can delete VNI pools as long as none of the VNIs within the pool are in use.
  1. Either from the table view (Resources > VNI Pools) or the details view, click the Delete button for the pool to delete.
  2. Click Delete to delete the pool and return to the table view.
