Virtual Local Area Networks (VLANs) are an essential tool for network administrators to divide a network into smaller, isolated groups. This allows for improved network performance, better security, and simplified network management. In this guide, we’ll walk you through the steps to set up VLANs with switchport mode access.
Step 1: Plan Your VLANs
Before you begin setting up VLANs, you need to have a plan in place for how you want to divide your network. Consider your organization’s needs, such as separating departments or creating a guest network. Make a list of each VLAN you want to create, along with a brief description of its purpose.
Step 2: Configure Your VLANs on the Switch
Once you have a plan in place, you can begin configuring your VLANs on the switch. Access the switch’s command line interface (CLI) and enter the following commands:
Switch# configure terminal Switch(config)# vlan <vlan-id> Switch(config-vlan)# name <vlan-name>
vlan-id> with the VLAN number you want to create and
<vlan-name> with a descriptive name for the VLAN.
Repeat this process for each VLAN you want to create.
Step 3: Assign Ports to VLANs
Now that you have created your VLANs, you need to assign ports to each VLAN. To do this, enter the following commands:
Switch(config)# interface <interface-id> Switch(config-if)# switchport mode access Switch(config-if)# switchport access vlan <vlan-id>
<interface-id> with the ID of the port you want to assign to a VLAN and
<vlan-id> with the ID of the VLAN you want to assign the port to.
Repeat this process for each port you want to assign to a VLAN.
Step 4: Verify Your Configuration
Once you have assigned all your ports to VLANs, you should verify your configuration to ensure everything is working as intended. Enter the following command:
Switch# show vlan brief
This will display a summary of all VLANs configured on the switch, along with the ports assigned to each VLAN.
You can also use the following command to verify a specific port’s VLAN assignment:
show interfaces <interface-id> switchport
This will display detailed information about the specified port, including its VLAN assignment.
Setting up VLANs with switchport mode access is a straightforward process that can greatly improve your network’s performance, security, and management. By following these steps, you can divide your network into isolated groups and assign ports to each VLAN with ease.
