# How to Isolate Management Machines from Production

**This guide explains how to isolate management machines to improve security.**

A Nutanix cluster contains two different types of management machines after delivery:

- VM, 1 CVM per node plus Prism Central
- Physical servers (nodes)

To increase the security of management machines, it is recommended to isolate them from the production environment.

## Requirements

- A Nutanix cluster in your OVHcloud account

## Instructions

### Step 1

Connect to the Prism Central Web interface.

Go to `Network & Security` and open `Subnets`.

 

### Step 2

In this example, VLAN 0 is associated with the "base" subnet on the "vs0" virtual switch.

To isolate the management network, you can use a new subnet in VLAN 1 for example.

To do this, click on `Create Subnet`.

 

Enter a name for your network, then select a VLAN ID, cluster, and the "vs0" virtual switch.

Then click `Save`.
