In this tutorial I’ll discuss about how to configuration vlan trunk on  switch cisco packet tracer. Vlan trunk can be carrier multiple vlan, use for point to point connection between two switch, switch and router, switch and server. It can be load multiple vlan connection in one time.

The following is the topologi are used :

Configure ip address for PC :

Create vlan on Switch 1 :

SW1(config)#vlan 10
SW1(config-vlan)#name ADMIN
SW1(config-vlan)#exit
SW1(config)#vlan 20
SW1(config-vlan)#name IT
SW1(config-vlan)#exit
SW1(config)#

Create vlan on Switch 2 :

SW2(config)#vlan 10
SW2(config-vlan)#name ADMIN
SW2(config-vlan)#exit
SW2(config)#vlan 20
SW2(config-vlan)#name IT
SW2(config-vlan)#exit
SW2(config)#

Assign vlan port on Switch 1 :

SW1(config)#int fa0/2
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 10
SW1(config-if)#exit
SW1(config)#int fa0/3
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 20
SW1(config-if)#exit

Assign vlan port on Switch 2 :

SW2(config)#int fa0/2
SW2(config-if)#switchport mode access
SW2(config-if)#switchport access vlan 10
SW2(config-if)#exit
SW2(config)#int fa0/3
SW2(config-if)#switchport mode access
SW2(config-if)#switchport access vlan 20
SW2(config-if)#exit
SW2(config)#

Test connection PC0 (Network VLAN10) from Switch1 to PC3 (VLAN10) from Switch2. Connection is timeout.

Test connection PC2 (Network VLAN20) from Switch1 to PC4 (VLAN20) from Switch2. Connection is timeout.

Configure Vlan trunk between Switch1 and Switch2 so that connection vlan10 and vlan20 from switch1 and switch2 can be connected.

Configure vlan trunk Switch1 :

SW1(config)#int fa0/1
SW1(config-if)#switchport mode trunk
SW1(config-if)#exit
SW1(config)#

Configure vlan trunk Switch2 :

SW2(config)#int fa0/1
SW2(config-if)#switchport mode trunk
SW2(config-if)#exit
SW2(config)#

Now repeat connection test again :

Connection vlan10 between switch1 and switch2, vlan20 between switch1 and switch2 is successfull.
