VTP
VTP adalah adalah suatu
protokol untuk mengenalkan suatu atau sekelompok VLAN yang telah ada agar dapat
berkomunikasi dengan jaringan. Atau menurut sumber lain mengatakan suatu metoda
dalam hubungan jaringan LAN dengan ethernet untuk menyambungkan komunikasi
dengan menggunakan informasi VLAN, khususnya ke VLAN.
VLAN Trunking Protocol
(VTP) merupakan fitur Layer 2 yang terdapat pada jajaran switch Cisco Catalyst,
yang sangat berguna terutama dalam lingkungan switch skala besar yang
meliputi beberapa Virtual Local Area Network (VLAN).

Di atas VLAN 10 dan 20 sudah terSynkron kan, tinggal memasukkan
Port interface pada VLAN tersebut sesuai dengan topology.
IDN-Lantai1(config)#int f0/2
IDN-Lantai1(config-if)#sw mode

IDN-Lantai1(config-if)#sw

Sekarang coba tambahkan VLAN 30 (FISIP), 40 (FE), 50 (FKM) di SWITCH Server, maka lihat hasilnya pada SWITCH Lantai 2
(Client):
IDN-SERVER(config)#vlan 30
IDN-SERVER(config-vlan)#name FISIP
IDN-SERVER(config-vlan)#vlan 40
