Fabric Virtualization – Manage vNET

Caution: Manage vNET is an Early Field Trial (EFT) feature. EFTs are intended for test environments and are not supported for use in production networks. You should consult your local partner or Arista Networks account team before using any EFT feature or to provide feedback.

There are features and functions used in Arista NetVisor UNUM and Insight Analytics that are common throughout the user interface (UI). Please refer to the Common Functions section for more information on the use of these functions and features.

Manage vNET

Please refer to the Understanding Virtual Networks (vNETS) section for more information about vNETs.

Selecting Manager → Fabric Virtualization → Manage vNET displays the Manage vNET dashboard with a list of any existing vNets.

Select the applicable Fabric from the left-hand navigation bar and the dashboard updates showing all vNET entries from all switches within the Fabric. 

Note: If no entries exist a "No Data Exists" message is displayed. You must first configure an entry on a switch. Prerequisite settings and configuration may be required.

The dashboard displays a list of existing vNET entries by Fabric and sorted using a drop-down selector. 

Additional parameters include: Switch, Name, Scope, VLAN, Admin, vNET Shared Ports, VXLAN IDs Assigned to vNET, Type of VLAN for this vNET, vNET Exclusive Port, Number of Private VLAN, Number Bridge Domains, Public VLAN, and Shared Port VLAN.

Create a Virtual Network (vNET)

Create a vNET by selecting Create a Virtual Network vNET. 

Please refer to Fabric Virtualization - Virtual Networks (vNETs) and vNET User Groups below noting the special case details.

Note: Switch / FRG only appears when creating a vNET with a fabric selected from the Left-Hand Navigation (LHN) pane. Otherwise, only Name appears when selecting an individual switch. For more information about Fabric Resource Groups refer to the Manage Groups section.
