VLAN (Virtual Lan) Configuration On Cisco Packet Tracer
What’s VLAN?
A VLAN (Virtual Local Area Network) is a method of creating separate logical networks within a physical network infrastructure. VLANs enable network administrators to segment a physical network into multiple virtual networks, each acting as if it were a separate physical network. This segmentation allows for better network management, security, and efficiency.
In a VLAN setup, devices within the same VLAN can communicate with each other as if they were connected to the same physical network switch, even if they are physically located on different switches. Devices in different VLANs typically require a router or layer 3 switch to communicate with each other.

VLANs are commonly used in enterprise networks to group devices based on department, function, or security requirements. They are also utilized in cloud environments and data centers to provide isolation and flexibility in network design.
Steps to Configure VLAN on Cisco Packets Tracer:
Step 1: First open the Cisco packet tracer desktop and create a network topology something like the image.
- Assign IP address to all PCs.
Step 2: After making the basic settings, create 3 different VLAN groups according to the topology you have created on the Switch. Use the following commands to create a VLAN by topology.
- Verify the configuration afterwards to ensure accuracy.
Step 3: After creating VLANs for departments, you need to make clients connected to the Switch interface to VLANs.
- After adding the Switchport to the VLANs, check the interfaces you have created and made on the Switch with the show vlan command.
Step 4: To send a message from one network to another.
Step 5: After configuring VLAN, Ping the computers again to check the network connection.
- Pinging from 192.168.10.10 to 192.168.20.10 will succeed as follows.
