VLAN, did you know vlan configuration?.

TOPOLOGI

Departemen Produksi:

• VLAN ID: 51
• Port Switch: Fa0/1 → Laptop produksi 1
• Port Switch: Fa3/1 → Laptop produksi 2

Departemen Penjualan:

• VLAN ID: 52
• Port Switch: Fa1/1 → Laptop penjualan 1
• Port Switch: Fa6/1 → Laptop penjualan 2

Departemen Marketing:

• VLAN ID: 53
• Port Switch: Fa2/1 → Laptop marketing 1
• Port Switch: Fa7/1 → Laptop marketing 2

🛠️ LANGKAH KONFIGURASI VLAN DI SWITCH

1. Masuk ke Mode Konfigurasi

Switch> enable
Switch# configure terminal

2. Buat VLAN Baru

Switch(config)# vlan 51
Switch(config-vlan)# name PRODUKSI
Switch(config-vlan)# exit

Switch(config)# vlan 52
Switch(config-vlan)# name PENJUALAN
Switch(config-vlan)# exit

Switch(config)# vlan 53
Switch(config-vlan)# name MARKETING
Switch(config-vlan)# exit

3. Assign Port ke VLAN

VLAN 51 — Produksi

Switch(config)# interface fastethernet 0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 51
Switch(config-if)# exit

Switch(config)# interface fastethernet 3/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 51
Switch(config-if)# exit

VLAN 52 — Penjualan

Switch(config)# interface fastethernet 1/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 52
Switch(config-if)# exit

Switch(config)# interface fastethernet 6/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 52
Switch(config-if)# exit

VLAN 53 — Marketing

Switch(config)# interface fastethernet 2/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 53
Switch(config-if)# exit

Switch(config)# interface fastethernet 7/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 53
Switch(config-if)# exit

4. Simpan Konfigurasi

Switch# write memory

atau

Switch# copy running-config startup-config
Destination filename [startup-config]? (tekan Enter)

5. Verifikasi Konfigurasi

Untuk memastikan bahwa VLAN dan port sudah terkonfigurasi dengan benar:

Switch# show vlan brief

Contoh hasil:

VLAN Name                             Status    Ports
---- -------------------------------- --------- --------------------------
1    default                          active    Fa4/1, Fa5/1
51   Produksi                         active    Fa0/1, Fa3/1
52   Penjualan                        active    Fa1/1, Fa6/1
53   Marketing                        active    Fa2/1, Fa7/1

✅ Pengujian:

• Laptop Produksi 1 ↔ Produksi 2 → Ping ✔️
• Laptop Penjualan 1 ↔ Penjualan 2 → Ping ✔️
• Laptop Marketing 1 ↔ Marketing 2 → Ping ✔️
• Laptop Produksi ↔ Penjualan / Marketing → Ping ❌ (karena beda VLAN)
