Introduction

This tutorial will guide you through configuring access ports on a Cisco switch and assigning them to specific VLANs (Virtual Local Area Networks). Understanding VLAN configuration is essential for managing and segmenting network traffic effectively, a key skill for obtaining your CCNA certification.

Step 1: Access the Switch Configuration

Open your terminal or console application to connect to the Cisco switch.
Enter the privileged EXEC mode by typing:
```
enable
```
Access the global configuration mode by entering:
```
configure terminal
```

Step 2: Create VLANs

To create a VLAN, use the following command:
```
vlan [VLAN_ID]
```
Replace [VLAN_ID] with the desired VLAN number (e.g., 10, 20).
Assign a name to the VLAN for easier identification:
```
name [VLAN_NAME]
```
Replace [VLAN_NAME] with a descriptive name (e.g., "Sales").

Step 3: Configure Access Ports

Identify the interface you want to configure as an access port. Enter the following command:
```
interface [INTERFACE_ID]
```
Replace [INTERFACE_ID] with the actual interface (e.g., FastEthernet0/1).
Change the port mode to access:
```
switchport mode access
```
Assign the interface to the VLAN you created:
```
switchport access vlan [VLAN_ID]
```
Again, replace [VLAN_ID] with the VLAN number you want to associate.

Step 4: Verify Configuration

Exit the interface configuration mode:
```
exit
```
To check the VLAN configuration, use:
```
show vlan brief
```
Verify that the port configurations are correct by using:
```
show running-config
```
This command will display the current configuration for all interfaces.

Conclusion

In this tutorial, you learned how to configure access ports on a Cisco switch and assign them to specific VLANs. Remember to save your configuration changes using:

write memory

or

copy running-config startup-config

As a next step, consider practicing these commands in a lab environment using Packet Tracer or similar simulation software to solidify your understanding and prepare for the CCNA exam.
