Basic Networking

1. Dasar Langkah-Langkah Konfigurasi VLAN
By Lukman, SE, M.Kom
1. Mendefinisikan VLAN IDdari 1 s/d 1005
Ada 5 VLAN ID yang tidakdipakai untukkegunaandefault(1,1002,1003,1004,1005)
Switch#configterminal
Switch(config)#vlan10 >>> mendefinisikanvlan idyangke 10 dgn nama teacher
Switch(config-vlan)#name teacher
Switch(config-vlan)#vlan50 >>> mendefinisikanvlanidyangke 50 dgn nama student
Switch(config-vlan)#name student
Switch(config-vlan)#end
Switch#showvlan >>> melihatkonfigurasi vlan yangsudahdidefinisikan
2. Menentukan/mengarahkan portpadaswitchyang akan digunakanuntukmasing-masingvlan
a. MengaktifkanportfastEthernet0/2 yg akan digunakanuntukvlan-id10(vlanteacher)
Switch#configterminal
Switch(config)#interface fa0/2
Switch(config-if)#switchportmode access
Switch(config-if)#switchportaccessvlan10
Switch(config-if)#end
b. MengaktifkanportfastEthernet0/5 yg akan digunakanuntukvlan-id50(vlanstudent)
Switch#configterminal
Switch(config)#interface fa0/5
Switch(config-if)#switchportmode access
Switch(config-if)#switchportaccessvlan50
Switch(config-if)#end
Catatan :
Jikaakan mengarahkanbeberapaportsecarabersamaanpadasatu anggota VLAN, misalnya
mengarahkanportfa0/10 s.dfa0/24 ke VLAN-ID50, maka cara konfigurasnyaadalah:
Switch#configterminal
Switch(config) interface range fa0/10 – fa 0/24

2. Switch(config-if-range)#switchportmode access
Switch(config-if-range)#switchportaccessvlan50
Switch(config-if-range)#end
