VLAN on Packet Tracer

In this tutorial, we are going to apply VLAN on packet tracer. Let us create a topology with one switch and multiple hosts like in the figure below.

if we go to the switch and enter the command “show vlan ”. It shows the following. 
 
As we can see in the figure above all the interfaces are being displayed and they are all the part of the default vlan 1. Now let us apply vlans on the switch. We are going to create three vlans as follows.
 
Now, that we have created the vlans. Lets see if they are visible to us.

In the above figure, vlans are visible. Now, we are going to assign interfaces to vlans. They are two ways to do this.
i. We can select an interface and assign that interface to a specific vlan
ii. We can select multiple interfaces (range of interfaces) at once and assign those interfaces to vlan.
In the figure below, we have done both of these.


Now, when we write “show vlan “ command and observe it. We will realize that interfaces have been assigned to desired vlans respectively.
 
Let us assign IP addresses to PCs. Open the PC.
 
Assign IP address.
 
After assigning IP addresses, when we try to communicate between two PCs belonging to two different vlans, it will fail. Thus, we have achieved our purpose.
 
The message sending failure status can be seen in the bottom right corner.
