14.9.11 Packet Tracer - Layer 2 Vlan Security Apr 2026

A Virtual Local Area Network (VLAN) is a logical grouping of devices on a network that are configured to communicate as if they were attached to the same physical network segment. VLANs are used to segment a network into smaller, more manageable parts, improving security, reducing broadcast traffic, and enhancing network performance.

Configuring Layer 2 VLAN Security with 14.9.11 Packet Tracer**

S1(config)#interface fastEthernet 0/2 S1(config-if)#switchport mode access S1(config-if)#switchport access vlan 20 14.9.11 packet tracer - layer 2 vlan security

In this article, we have demonstrated how to configure Layer 2 VLAN security using the 14.9.11 Packet Tracer. By implementing VLANs and configuring VLAN security features, you can enhance the security and integrity of your network. Remember to always follow best practices and test your configurations thoroughly to ensure a secure and stable network.

3. **Assign Ports to VLANs**: Assign ports to VLANs using the commands: S1(config)#interface fastEthernet 0/1 S1(config-if)#switchport mode access S1(config-if)#switchport access vlan 10 A Virtual Local Area Network (VLAN) is a

S1(config)#vlan 30 S1(config-vlan)#name Marketing S1(config-vlan)#exit

This allows only VLANs 10 and 20 to pass through port Fa0/4. 2. **Port Security**: Configure port security to restrict unauthorized access to the network: S1(config)#interface fastEthernet 0/1 S1(config-if)#switchport port-security S1(config-if)#switchport port-security maximum 2 S1(config-if)#switchport port-security violation restrict “` This configuration allows only two devices to connect to port Fa0/1 and restricts any additional connections. **Assign Ports to VLANs**: Assign ports to VLANs

S1(config)#interface fastEthernet 0/3 S1(config-if)#switchport mode access S1(config-if)#switchport access vlan 30
