Virtual LAN (VLAN) membagi satu broadcast domain menjadi beberapa broadcast domain, sehingga dalam satu switch bisa saja terdiri dari beberapa network, host yang berbeda vlan tidak akan tersambung sehingga meningkatkan security jaringan.

VLAN adalah fasilitas yang dimiliki oleh switch manageable, contohnya cisco pada swith unmanageble , port portnya hanya dapat digunakan untuk koneksi ke network yang sama (satu network) sehingga mendukung fasailitas VLAN

Switch(config)#vlan 10

Switch(config-vlan)#name A

Switch(config-vlan)#exit

Switch(config)#vlan 20

Switch(config-vlan)#name B

Switch(config-vlan)#exit

Switch(config)#interface FastEthernet0/1

Switch(config-if)#switchport access vlan 20

Switch(config-if)#exit

Switch(config)#interface FastEthernet0/2

Switch(config-if)#switchport access vlan 20

Switch(config-if)#exit

Switch(config)#interface FastEthernet0/3

Switch(config-if)#switchport access vlan 10

Switch(config-if)#exit

Switch(config)#interface FastEthernet0/4

Switch(config-if)#switchport access vlan 10

Switch(config-if)#no shutdown
