Here in this experiment, we are going to configure three VLANs with VLAN ID 10, 20 and 30 along with names SALES, HR, ENG., respectively. For details please refer the table 1, given below.

Here in this section, we will discuss about the three important concept about the VLAN.

1. 1. What is a VLAN?


2. 2. Why do we required VLANs in an Enterprise LAN Set-up?


3. 3. How the Shared ICT Infrastructure works using VLAN?

To configure a VLAN the flowing steps are followed:

• # Creating a VLAN with VLAN ID
• # Providing a Name to the VLAN
• # Assigning ports or interfaces to the respective VLAN
• # Making the port as access or trunk port
• # Providing an IP Address to VLAN
• # Creating DHCP pool for individual VLAN (if required)
• # Exempting IP Addresses for each DHCP Pool.

We will follow these steps in similar manner for configuring multiple VLAN in a switch or across a set of switches.

To carry out this virtual experiment in the actual environment we require the following equipment:

1. # Switch (1 Nos.)


2. # Laptop or Desktop (1 No.)


3. # Console Cable (1 No.) with Comm. to USB converter in case you are using a Laptop, or


4. # Mini console cable with USB Connector.

Dear Learners,
Let us know watch the video that will provide you a idea about how to perform the experimental setup and configure individual VLAN in a Layer 2 Device(s) such as a Managed Switch or a set of Managed Switches.
