Tutorial - Cara Konfigurasi VLAN pada Cisco Packet Tracer (Untuk Pemula)

Introduction

This tutorial provides a step-by-step guide on how to configure VLANs using Cisco Packet Tracer, aimed at beginners. VLANs (Virtual Local Area Networks) are essential for network segmentation and improving overall network efficiency. By the end of this tutorial, you'll be able to create and manage VLANs within Cisco Packet Tracer.

Step 1: Set Up Your Network Environment

• Launch Cisco Packet Tracer.
• Create a new project and save it.
• Drag and drop the necessary devices:
  • Switches (e.g., 2960 model).
  • End devices (e.g., PCs).
• Connect the devices using appropriate cables (typically straight-through cables for connecting switches to PCs).

Step 2: Access the Switch Configuration

• Click on the switch to open its configuration window.
• Navigate to the "CLI" (Command Line Interface) tab to start configuring the switch.

Step 3: Enter Global Configuration Mode

• Type the following command to enter global configuration mode:

  enable
  configure terminal
  

• This mode allows you to make changes to the switch's configuration.

Step 4: Create VLANs

• To create a VLAN, use the following command:

  vlan [VLAN_ID]
  

  • Replace [VLAN_ID] with your desired VLAN number (e.g., 10, 20).
• Assign a name to the VLAN for easier identification:

  name [VLAN_Name]
  

Step 5: Assign Ports to the VLAN

• To assign a port to the VLAN, enter interface configuration mode:

  interface [interface_ID]
  

  • Replace [interface_ID] with the specific port number (e.g., FastEthernet0/1).
• Set the port to access mode and assign it to the VLAN:

  switchport mode access
  switchport access vlan [VLAN_ID]
  

Step 6: Verify VLAN Configuration

• Exit back to global configuration mode:

  exit
  

• To view the VLANs configured on the switch, use:

  show vlan brief
  

• This command displays a summary of the VLANs and the ports assigned to them.

Step 7: Test Connectivity

• Assign IP addresses to the PCs in different VLANs to ensure they are on separate subnets.
• Use the command prompt on each PC to ping devices in the same VLAN to test connectivity.

Common Pitfalls to Avoid

• Ensure that you are in the correct mode (global or interface) when entering commands.
• Double-check VLAN IDs and port assignments to avoid misconfigurations.
• Remember to save your configuration with:

  write memory
  

Conclusion

In this tutorial, you learned how to configure VLANs on a Cisco switch using Packet Tracer. Key steps included creating VLANs, assigning ports, and verifying the configuration. As a next step, consider exploring inter-VLAN routing or experimenting with more complex network topologies to deepen your understanding of VLAN functionality. Happy networking!
