* Trunking pada Port Switch

Sebuah VLAN Native ditandai dengan sebuah port trunk 802.1Q. Sebuah port trunk 802.1Q mendukung traffic dari banyak VLAN sama seperti traffic yang tidak berasal dari sebuah VLAN. Trunk adalah link point-to point diantara satu atau lebih interface ethernet device jaringan seperti router atau switch. Trunk Ethernet membawa lalu lintas dari banyak VLAN melalui link tunggal. Sebuah VLAN trunk mengijinkan kita untuk memperluas VLAN melalui seluruh jaringan. Jadi link Trunk digunakan untuk menghubungkan antar device intermediate. Dengan menggunakan port trunk, dapat digunakan sebuah link fisik untuk menghubungkan banyak VLAN.

Sebuah Port pada Switch Cisco Catalyst mempunyai beberapa mode trunk. Mode trunking tersebut didefinisikan untuk negosiasi antar port yang saling berhubungan dengan menggunakan Dynamic Trunking Protocol (DTP). DTP merupakan sebuah protokol keluaran Cisco. Switch dari vendor lain tidak mendukung DTP. DTP mengatur negosiasi mode trunk hanya jika port switch dikonfigurasi dalam mode trunk yang mendukung DTP. DTP mendukung baik ISL maupun 802.1Q. Ada tiga mode trunk pada DTP, yaitu: Trunk, Access, Dynamic Auto dan Dynamic Desirable.



* Native VLAN

Native VLAN dikeluarkan untuk port trunking 802.1Q. port trunking 802.1Q mendukung lalu lintas jaringan yang datang dari banyak VLAN (tagged traffic) sama baiknya dengan yang datang dari sebuah VLAN (untagged traffic). Port trunking 802.1Q menempatkan untagged traffic pada Native VLAN.

* Native VLAN digunakan untuk :
- Untuk kompatibilitas pada system yang lebih tua.
- relevan untuk trunk port ( trunk port membawa traffic pada multiple VLAN).
- VLAN di diidentifikasi oleh sebuah “tag” di dalam sebuah frame.
- Native VLAN tidak memiliki tag.

* kenapa VLAN 1 di buat sebagai native . . ? ?
karena VLAN 1 merupakan default Ethernet LAN, semua port awalnya merupakan anggota VLAN 1.
