VLAN adalah suatu pengelompokan host-host mengurangi

tingkat traffic.

Kelebihan VLAN

• Mengurangi broadcast domain

• Mengelompokan host-host

• Memperkuat keamanan

CARA MEMBUAT VLAN PADA SWITCH:

• CARA MEMBUAT VLAN PADA SWITCH:

Switch(config)#vlan 10

Switch(config-vlan)#name srii

Switch(config-vlan)#ex


Switch(config-vlan)#name hartinahhh

Switch(config-vlan)#int fa0/1

Switch(config-if)#swi

Switch(config-if)#switchport mode access

Switch(config-if)#switchport vlan 10

Switch(config-if)#sw

Switch(config-if)#switchport access vlan 10

Switch(config-if)#ex

Switch(config)#int fa1/1

• Menghubungkan vlan pada 2 switch

• Tambahkan vlan 10 dan 20 dan beri nama pada kedua switch


Switch(config-vlan)#name sri



Switch(config-vlan)#name hartina

• Kemudian kita kelompokan host-host tersebut berdasarkan interface pada switch

pertama:

Switch(config-vlan)#int fa0/1




• Kemudian kita kelompokan host-host tersebut berdasarkan interface pada switch

kedua:

Switch(config-if)#switchport mode trunk

KONFIGURASI DHCP PADA SWITCH MULTI LAYER

• Konfigurasi pada CLI untuk memberi IP dengan menggunakan DHCP

• Konfigurasi pada DHCP1:

• Konfigurasi pada DHCP2:

• Rubah IP CONFIGURATION dari static menjadi DHCP

• Pada PC

• Pada LAPTOP:

• Kemudian PING

• Antara PC dengan PC

• Antara LAPTOP dengan LAPTOP

• Antara PC dengan LAPTOP
