 ====== Cisco : VLAN ======
 VLAN (Virtual Local Area Network) adalah sebuah metode untuk membagi satu jaringan komputer fisik menjadi beberapa jaringan virtual yang terpisah. Hal ini memungkinkan Anda untuk mengelompokkan komputer berdasarkan fungsi, departemen, atau proyek—tanpa harus mengubah kabel fisik yang sudah ada.

-==== Topologi ====
+===== Topologi =====
 {{ :networking:cisco:cisco_vlan.png?nolink |}}
 "Sebelum konfigurasi VLAN, keempat end host berada dalam LAN yang sama (192.168.0.0/24) dan dapat saling berkomunikasi. Setelah mengonfigurasi VLAN, kita akan membagi topologi tersebut menjadi dua VLAN terpisah untuk mengisolasi lalu lintas data (traffic)."
 Goalsnya adalah untuk memisahkan Devices sesuai VLAN pada topology
   * VLAN 10 - PC1,PC2
-  * VLAN 10 - PC3,PC4
+  * VLAN 20 - PC3,PC4
-==== Konfigurasi ====
+===== Konfigurasi =====
+  * **Step 1 : Pembuatan VLANs**
+<code>
+Switch(config)#vlan 10
+Switch(config-vlan)#name BIRU
+Switch(config-vlan)#exit
-=== Router C2691 ===
+Switch(config)#vlan 20
+Switch(config-vlan)#name MAGENTA
-<code>
+Switch(config-vlan)#exit
-// Masuk Global Configration mode
+</code>
-C2691> enable
+  * **Step 2 : Assign VLANs ke Ports**
-C2691# configure terminal
+<code>
-C2691(config)#
+Switch(config)#interface f0/1
-//setup ip interface gateaway
+Switch(config-if)#switchport mode access
-C2691(config)#interface f0/0
+Switch(config-if)#switchport access vlan 10
-C2691(config-if)#ip address 192.168.0.1 255.255.255.0
+Switch(config-if)#exit
-// Setup DHCP Server
+Switch(config)#interface f0/2
-C2691(config-if)#ip dhcp pool LAN
+Switch(config-if)#switchport mode access
-C2691(dhcp-config)#network 192.168.0.0 255.255.255.0
+Switch(config-if)#switchport access vlan 10
-C2691(dhcp-config)#default-router 192.168.0.1
+Switch(config-if)#exit
-C2691(dhcp-config)#exit
+</code>
-C2691(config)#ip dhcp excluded-address 192.168.0.1 192.168.0.100
+Dapat dapat juga menggukan ''interface range'' untuk menkongigurasi banyak interface secara bersamaan:
+<code>
+Switch(config)#interface range f0/3-4
+Switch(config-if-range)#switchport mode access
+Switch(config-if-range)#switchport access vlan 20
+</code>
+  * **Step 3 : Check VLAN Summary**
+<code>
+Switch#show vlan brief
+</code>
+Sample Output:
+<code>
+VLAN Name                             Status    Ports
+---- -------------------------------- --------- -------------------------------
+    default                          active    Fa0/5 - Fa0/24, Gig0/1, Gig0/2
+   BIRU                             active    Fa0/1, Fa0/2
+   MAGENTA                          active    Fa0/3, Fa0/4
+fddi-default                     active
+token-ring-default               active
