UNUM Appliance OVA - UNUM-6.3.0-xxxx.xx.-st.ova

Virtual Netvisor OVA - VNV-6300315465.ova (example version number only).

Note: The downloaded vNV version has to match your installed switch OS version.

2.Activate VMware License using the steps illustrated below.

Usage Note: DHCP or Static IP addresses can be assigned. A DHCP server must be running for an automatic IP address assignment during ESXi configuration.

For Static IP addressing, select static from the setup script and enter the static IP parameters for UNUM and vNV.

3.Configure ESXi and create a new Virtual Machine (VM) using the configuration examples illustrated below.

4.Connect to the UNUM host via a terminal session using SSH (using the assigned IP address) and run the following script:


5.Deploy a standalone VM.

ESXi Obtain License

From the ESXi Management Interface, determine if a license is enabled.

Click the Licensing tab to display the current license status.

If a valid license is missing, the following dashboard is displayed.

ESXi Management Interface - Licensing Tab - No License

General Deployment Details and Management Scenarios

Arista NetVisor UNUM

1.Deploy VM.

2.Eth0 obtains a DHCP IP Address.

3.Login to the VM and set up the Eth1 IP address.

4.Add vnv(s) as a Seed Switch for UNUM. Performed post vNV config/ setup.


1.Deploy VM.

2.Obtain vmgmt0 IP address for vNV from DHCP.

3.Disconnect the Network adapter 1 on the VM.

4.Accept EULA.

5.If fabric name is specified: join fabric and errors out under the following conditions:

a)fabric doesn't exist or is not reachable or is running a different version

Provisioning Details and Steps for Inband Scenario

Configuration Steps for VEP

ESXi Configuration:

1.Create a Vswitch on the ESXi host with the following settings:

a)promiscuous mode enabled

b)allow forged transmits

2.Portgroup is created (with optional VLAN parameter; defaults to 0 (untagged))

3.Assign a vnic to the vswitch. This vnic is the physical port connected to the switch and needs to be entered correctly by the user for configuration to succeed. Without this is the physical link, the vNV cannot find the fabric to join.

vNV Configuration:

1.vNV’s Network Adapter 3 assigned to this port group.

2.vdata0 interface on vNV needs an IP address configured in the same network as the inband IP address of the switch.

3.vNV should have web-enabled on data using: admin-service-show if mgmt web (same as the management scenario).
