Virtual Appliance Pre-Requisites

Deploy NetVisor UNUM  as a VM (Virtual Machine) on a VMware ESXi Hypervisor.

Currently, NetVisor UNUM 6.3.x requires either ESXi, VMware vSphere Enterprise, VMware vSphere Standard, and vCenter 6.7 versions.

For High Availability (HA), NetVisor UNUM supports both VMware vSphere Enterprise and VMware vSphere Standard with applicable licensing.

We do not support other VMware versions for NetVisor UNUM 6.3.x

Please consult the specific NetVisor UNUM Release Note for the NetVisor UNUM version you are using for more information regarding supported VMware versions.

The instructions in this document assume the administrator has access to a VMware vCenter console with privileges adequate to create a Virtual Machine and has the necessary Linux system administration skills.

VM comes in an OVA format.

The NetVisor UNUM VM requires the following: 

NetVisor UNUM virtual machine (software) and server hardware requirements can vary based on the NetVisor UNUM options chosen (BASE, Medium Capacity, or High Capacity). Please consult the NetVisor UNUM datasheet tables for the most up-to-date requirements.

Network: three Ethernet interfaces configured as:

Note: Please carefully review the following usage information regarding the Ethernet adapters used by Arista NetVisor UNUM.


used for management, GUI (user interaction) and data collection via Netvisor REST. This interface uses DHCP by default.


Eth1: is used for internal system communication. A standalone Arista NetVisor UNUM VM instance REQUIRES the use of an IP address for eth1 before normal operations begin. Arista recommends adding the Eth1 IP address to a dummy vSwitch and a separate dummy subnet on the ESXi host.

WARNING! If you change the IP address of Eth1 in a cluster configuration, you disrupt normal operations. Please contact Technical Support if you need or want to change the Eth1 address in a cluster configuration.


<Optional> used to connect a Seed Switch or Fabric via an inband connection.

Note: To connect more than one Fabric via inband and external switch is required.
