Trunking VLAN di Cisco Packet Tracer

TRUNKING VLAN

Trunking berfungsi untuk meleawtkan traffic VLAN dari switch yg berbeda. Antara swtch lantai 1 dan lantai 2 bisa terhubung. PC0, PC1, PC4 dan PC5 masuk dalam VLAN 10 sedangkan PC2, PC3, PC6 dan PC7 masuk dalam VLAN 20.

Lalu coba konfigurasikan VLAN seperti dibawah ini. Membuat VLAN 10 dan VLAN 20.

Switch0(config)#vlan 10

Switch0(config-vlan)#int fa0/1

Switch0(config-if)#sw access vlan 10

Switch0(config-if)#int fa0/2

Switch0(config-if)#sw access vlan 10

Switch0(config-if)#vlan 20

Switch0(config-vlan)#int fa0/3

Switch0(config-if)#sw access vlan 20

Switch0(config-if)#int fa0/4

Switch0(config-if)#sw access vlan 20

Switch0(config-if)#      

Switch1(config)#vlan 10

Switch1(config-vlan)#int fa0/1

Switch1(config-if)#sw access vlan 10

Switch1(config-if)#int fa0/2

Switch1(config-if)#sw access vlan 10

Switch1(config-if)#vlan 20

Switch1(config-vlan)#int fa0/3

Switch1(config-if)#sw access vlan 20

Switch1(config-if)#int fa0/4

Switch1(config-if)#sw access vlan 20

Switch1(config-if)#

Lalu konfigurasikan interface yg saling terhubung antar switch dengan mode trunk. Lakukan pada kedua switch ya...!!!

Switch0(config)#int fa0/10

Switch0(config-if)#switchport mode trunk

Switch0(config-if)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to up

Switch1(config)#int fa0/10

Switch1(config-if)#switchport mode trunk

Lakukan perintah ping dari satu PC ke PC yg lain dan juga ketikkan perintah show vlan

Catatan : PC hanya dapat melakukan ping kesesama VLAN beda switch namun tidak bisaa ke beda VLAN

Switch0#sh int trunk

Port Mode Encapsulation Status Native vlan

Fa0/10 on 802.1q trunking 1
