Di tengah perkembangan teknologi jaringan korporat yang makin pesat. VLAN cisco masih sangat popular di mata para network administrator. Bahkan, teknologi WAN yang notabennya identik dengan OSI Layer 3, sekarang kembali memakai OSI Layer 2, seperti kita lihat pada teknologi Metro Ethernet yang menghemat perangkat. Tidak perlu menggunakan router yang harganya mahal dan hanya menggunakan Switch sekelas Cisco 2900 series atau switch Layer 2 lainnya.Untuk masalah routing terserah kita apakah menggunakan dynamic route seperti EIGRP, BGP, OSPFatau menggunakan static route.

Sebenarnya, apa sih keuntungan menggunakan VLAN ?

1. Network administrator lebih mudah mengelola jaringan di suatu tempat baik secara fisik maupun secara logic.
2. Mengurangi broadcast domain
3. Memudahkan mengontrol trafik jaringan
4. Memberikan sistem keamanan jaringan yang lebih baik.

VLAN menguntungkan baik di sisi network administrator maupun penggunanya. Untuk Metro Ethernet, kita bisa membagi cabang dengan VLAN yang berbeda.Misal, cabang Jakarta menggunakan VLAN 1, cabang Bandung menggunakan VLAN 2, cabang Makasar menggunakan VLAN 3 dan seterusnya.

Untuk lingkungan kantor, network administrator bisa membagi VLAN berdasarkan departemen yang ada di perusahaan tersebut. Misalkan departemen HRD menjadi VLAN 1, departemen accounting menjadi VLAN 2 dan seterusnya.

VLAN terbagi menjadi port based, mac address based, maupun protocol based. Yang sering digunakan adalah VLAN port based karena jenis VLAN ini mudah dikonfigurasi dan mudah untuk diimplementasikan.

Jadi, ada yang mau berdiskusi tentang VLAN? Mari kita berbagi.
