JARINGAN KOMPUTER VLAN

Apa itu VLAN ???

Vlan (Virtual Local Area Network) adalah kelompok device dalam sebuah LAN yang dikonfigurasi (menggunakan software management) sehingga meraka dapat saling berkomonikasi asalkan dihubungkan dengan jaringan yang sama walaupun secara fisikal mereka pada segmen LAN yang berbeda. Secara logika, VLAN membagi jaringan ke dalam beberapa subnetwork.VLAN juga mengijinkan banyak subnet dalam jaringan yang menggunakan switch yang sama.

Dibawah ini sedikit penjelasan mengenai perintah pada switch dalam pembuatan Vlan :

Switch_Vlan(config-if)#switchport mode trunk

Perintah di atas di gunakan untuk menandakan sebuah port yang difungsikan ketika ada hubungan antara dua switch atau router dan switch yang membawa lalu lintas lebih dari satu VLAN. Sebuah port trunk harus menjalankan protokol trunking khusus. Protokol yang digunakan akan menjadi milik Cisco link Inter-switch (ISL) atau standar IEEE 802.1q.

Switch_Vlan(config-if)#switchport trunk native vlan 1

Perintah di atas di gunakan untuk Vlan management (switchport trunk native vlan vlan-id)
