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
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. 14.9.11 packet tracer - layer 2 vlan security
