Creating multiple vLANs in a vRack

This guide will show you how to create multiple vLANs within the vRack

Last updated 21/06/2018

Objective

The standard vRack configuration enables you to create only one vLAN. This means that you can only use each IP address once. However, with the vRack version 2.0 configuration, you can create up to 4,000 vLANs within a single vRack. This means that you can use each IP address up to 4,000 times.

This guide will show you how to create multiple vLANs within the vRack.

Requirements

Instructions

Linux

As an example, we'll use eth1 as the network interface, 10 as the vLAN tag, and 192.168.0.0/16 as the IP address range.

First, you need to establish an SSH connection to your server, and run the following commands from the command line. This will install the vLAN package on your server:

# sudo apt-get install vlan

Next, we need to create a vLAN tag. The tag is an identifier that allows you differentiate between multiple vLANs:

# vconfig add eth1 10

Added VLAN with VID == 10 to IF -:eth1:-

Next, we need to declare the IP address range within the vRack and tag it with our identifier. We can do this with the following command:

# ip addr add 192.168.0.0/16 dev eth1.10

Lastly, we need to amend the configuration of our network interface so that it takes into account the vLAN tag. For this step, you will need to open your network interface configuration file for editing, and amend it as shown below:

# sudo /etc/network/interfaces

auto eth1.10
iface eth1.10 inet static
address 192.168.0.50
netmask 255.255.0.0
broadcast 192.168.255.255

Windows

Log on to your server via a remote desktop connection, and open the Server Manager app. Then select Local Server. Now click the Disabled link next to NIC Teaming:

Windows vLAN

Next, create a new team by selecting a network interface, and typing a team name into the Team name field. When you have finished, click OK:

Windows vLAN

Next, we need to define the vLAN tag. In the Adapters and Interfaces pane of the NIC Teaming screen, right-click the interface you have just added to the new team, then click Properties. Now click Specific VLAN, and define the tag:

Windows vLAN

Next, we need to configure the IP address of the vLAN. Click the Start button on your keyboard, then click Control Panel:

Windows vLAN

Next, click Network and Internet:

Windows vLAN

Then Network and Sharing Center:

Windows vLAN

Then click Change adapter settings:

Windows vLAN

Next, right-click the vLAN interface, and click Properties:

Windows vLAN

Then double-click Internet Protocol Version 4 (TCP/IP/IPv4):

Windows vLAN

Next, click Use the following IP address. For IP address, type in an IP from your internal range. For Subnet mask, type in 255.255.0.0.

Windows vLAN

Finally, click the OK button to save the changes, then reboot your server.
