+==== Troubleshooting Trunk ====
+^ Command ^ Description ^
+| ''S1#show interfaces trunk'' | Menampilkan VLAN yang diizinkan pada trunk |
 ===== Topologi =====
-Gambar topology
+{{ :networking:cisco:cisco_trunk-rev.png?nolink |}}
-Goals Topology
+Pada toplogy terdapat 2 jaringan yang berbeda yaitu BIRU : ''192.168.1.0/24'' dengan VLAN 10 dan MAGENTA : ''192.168.2.0/24'' dengan VLAN 20. ''Interface gigabitethernet0/1'' akan menjadi links trunks yang mengubungkan vlan atas dan bawah.
+  * VLAN 10 - PC1,PC2,PC5,PC6 (BIRU)
+  * VLAN 20 - PC3,PC4,PC7,PC8 (MAGENTA)
 ===== Konfigurasi =====
-  * **Step 1 : Pembuatan VLANs**
+===== Konfigurasi  VLANs=====
+  * **Step 1 : Menset vlan 10,20 pada masing masing switch**
 <code>
-Switch(config)#vlan 10
+SW1(config)#vlan 10
-Switch(config-vlan)#name BIRU
+SW1(config-vlan)#name BIRU
-Switch(config-vlan)#exit
+SW1(config-vlan)#exit
+SW1(config)#vlan 20
+SW1(config-vlan)#name MAGENTA
+SW1(config-vlan)#exit
+</code>
+<code>
+SW2(config)#vlan 10
+SW2(config-vlan)#name BIRU
+SW2(config-vlan)#exit
+SW2(config)#vlan 20
+SW2(config-vlan)#name MAGENTA
+SW2(config-vlan)#exit
+</code>
-Switch(config)#vlan 20
+  * **Step 2 : Mengatur ports sesuai VLAN.**
-Switch(config-vlan)#name MAGENTA
+<code>
-Switch(config-vlan)#exit
+SW1(config)#interface range f0/1-2
+SW1(config-if-range)#switchport mode access
+SW1(config-if-range)#switchport access vlan 10
+SW1(config)#interface range f0/3-4
+SW1(config-if-range)#switchport mode access
+SW1(config-if-range)#switchport access vlan 20
 </code>
-  * **Step 2 : Assign VLANs ke Ports**
 <code>
-Switch(config)#interface f0/1
+SW2(config)#interface range f0/1-2
-Switch(config-if)#switchport mode access
+SW2(config-if-range)#switchport mode access
-Switch(config-if)#switchport access vlan 10
+SW2(config-if-range)#switchport access vlan 10
-Switch(config-if)#exit
+SW2(config-if-range)#exit
+SW2(config)#interface range f0/3-4
+SW2(config-if-range)#switchport mode access
+SW2(config-if-range)#switchport access vlan 20
+</code>
+===== Konfigurasi  Trunk=====
+  * **Step 1 : Mengatur trunk pada sisi SW1.**
+<code>
+SW1(config)#interface g0/1
+SW1(config-if)#switchport mode trunk
+SW1(config-if)#do show interfaces trunk
+Port        Mode         Encapsulation  Status        Native vlan
+Gig0/1      on           802.1q         trunking      1
+Port        Vlans allowed on trunk
+Gig0/1      1-1005
+Port        Vlans allowed and active in management domain
+Gig0/1      1,10,20
+Port        Vlans in spanning tree forwarding state and not pruned
+Gig0/1      1,10,20
+SW1(config-if)#switchport trunk allowed vlan 10,20
+SW1(config-if)#do show interfaces trunk
+Port        Mode         Encapsulation  Status        Native vlan
+Gig0/1      on           802.1q         trunking      1
+Port        Vlans allowed on trunk
+Gig0/1      10,20
+Port        Vlans allowed and active in management domain
+Gig0/1      10,20
+Port        Vlans in spanning tree forwarding state and not pruned
+Gig0/1      20
-Switch(config)#interface f0/2
+SW1(config-if)#exit
-Switch(config-if)#switchport mode access
+</code>
-Switch(config-if)#switchport access vlan 10
-Switch(config-if)#exit
+  * **Step 2 : Mengatur trunk pada sisi SW2.**
+<code>
+SW2(config)#interface g0/1
+SW2(config-if)#switchport mode trunk
+SW2(config-if)#switchport trunk allowed vlan 10,20
+SW2(config-if)#
