Installation Requirements
The following list contains the pre-requisites of Cisco Optical Network Controller 3.1 installation.
-
Before installing Cisco Optical Network Controller 3.1, you must first login in to the VMware customer center and download VMware vCenter server version 7.0, as well as vSphere server and client with version 7.0. Cisco Optical Network Controller 3.1 is deployed on rack or blade servers within vSphere.
-
ESXi host must be installed on servers with vSphere version of 6.7.0 or 7.0 to support creating Virtual Machines (VM).
-
Before the Cisco Optical Network Controller 3.1 installation, two networks are required to be created.
-
Control Plane Network:
The control plane network helps in the internal communication between the deployed VMs within a cluster. If you are setting up a standalone system, this can refer to any private network. However, in case of a High Availability (HA) cluster, this network is created between the servers where each node of the HA cluster is being created.
-
VM Network or Northbound Network:
The VM network is used for communication between the user and the cluster. It handles all the traffic to and from the VMs running on your ESXi hosts and this is your Public network through which the UI is hosted.

The requirements based on type of deployment are given in the table below.
Deployment Type |
Requirements |
---|---|
Standalone ( SA ) |
Control Plane: 1 IP ( this can be a private network). Northbound Network/VM Network: 1 IP (this must be a public network) |
Highly Available ( HA ) |
Control Plane: 3 IPs (this can be a private network) - IPs required for individual nodes. VM Network: 4 IPs ( this must be a public network) with 3 IPs for node management and 1 IP for Virtual IP, which is used for northbound communication and UI. |
Note |
For a High Availability (HA) deployment, nodes on different ESXi hosts should have a minimum link bandwidth of 10G between them. This is recommended to ensure efficient data communication and synchronization between the nodes. |
To create the control plane and virtual management networks follow the steps listed below.
-
From the vSphere client select the Datacenter where you want to add the ESXi host.
-
After adding the ESXi host create the Control Plane and VM Networks before deploying the SA or HA. The HA has four IPs where one is the primary and the others can join as secondary and tertiary IP addresses. The SA has only one IP. Also, in the case of HA the Virtual IP is the IP that exposes the active node to the user.
