Making a VLAN


In Cisco Packet Tracer, a VLAN (Virtual Local Area Network) is a virtualized network segment that allows you to logically separate devices into different broadcast domains. It enables you to group devices together based on specific criteria such as department, function, or security requirements, even if they are physically connected to the same switch

In Cisco Packet Tracer, a VLAN (Virtual Local Area Network) is a virtualized network segment that allows you to logically separate devices into different broadcast domains. It enables you to group devices together based on specific criteria such as department, function, or security requirements, even if they are physically connected to the same switch.

To create a VLAN in Cisco Packet Tracer, follow these steps:

Step 1: Build the network topology Drag and drop a switch from the Packet Tracer device panel onto the workspace. Connect the necessary devices, such as PCs or other switches, to the switch using appropriate interfaces.

Step 2: Access the switch's CLI Double-click on the switch to open the CLI (Command Line Interface).

Step 3: Enter VLAN configuration mode Enter the following commands in the switch's CLI to access the VLAN configuration mode:


enable

configure terminal


Step 4: Create a VLAN To create a VLAN, use the following command:


vlan vlan-id


Replace vlan-id with the desired VLAN ID. For example:

Copy code

vlan 10


Step 5: Assign switch ports to the VLAN To assign switch ports to the VLAN you created, use the following command:

interface interface-id

switchport access vlan vlan-id


Replace interface-id with the specific switch port (e.g., FastEthernet0/1) you want to assign to the VLAN, and vlan-id with the VLAN ID you created. For example:


interface FastEthernet0/1

switchport access vlan 10


Repeat this command for each switch port you want to assign to the VLAN.

Step 6: Exit VLAN configuration mode Exit the VLAN configuration mode by entering the following command:

exit


Step 7: Save and exit Save the configuration changes by entering the following commands:

copy running-config startup-config

exit


Here is an example of 2 VLANS in 1 network.


Router/Switch/Server:


Ena

Conf t

VLAN10

Name (Name of the VLAN)

No shutdown

Sh vlan

Sh vtp status


VLAN20

Name (Name of the VLAN20)

No shutdown

Sh vlan

Sh vtp status


By following these steps, you can create a VLAN in Cisco Packet Tracer and assign switch ports to the VLAN. This enables devices connected to those ports to be logically separated into the respective VLANs.
