cara setting vlan

Cara Membuat VLAN Simple Pada Cisco

VLAN disebut juga virtual LAN, pada tutorial kali ini akan dijelaskan bagaiman membuat VLAN pada CISCO. disini saya memakai simulasi CISCO yaitu Packet Tracer V5, sedangkan definisi VLAN sendiri anda bisa melihat disini

kita akan membuat 3 valan yaitu :
1. vlan 30 dosen
2. vlan 40 mahasiswa
3. vlan 50 karyawan

berikut gambarannya :

definisikan ip address gateway di router dengan membuat interface virtual :

– untuk gateway vlan 30

Router>enable

Password:

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#interface fa0/0.30

Router(config-subif)#encapsulation dot1Q 30

Router(config-subif)#ip address 192.168.30.254 255.255.255.0

Router(config-if)#exit

Router(config)#exit

%SYS-5-CONFIG_I: Configured from console by console

– untuk gateway vlan 40

Router>enable

Password:

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#interface fa0/0.40

Router(config-subif)#encapsulation dot1Q 40

Router(config-subif)#ip address 192.168.40.254 255.255.255.0

Router(config-if)#exit

Router(config)#exit

%SYS-5-CONFIG_I: Configured from console by console

– untuk gateway vlan 50

Router>enable

Password:

Router#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#interface fa0/0.50

Router(config-subif)#encapsulation dot1Q 50

Router(config-subif)#ip address 192.168.50.254 255.255.255.0

Router(config-if)#exit

Router(config)#exit

%SYS-5-CONFIG_I: Configured from console by console

Lalu kita setting switchnya, langkah-langkahnya sebagai berikut :
– Definisikan Vlan :

Switch#vlan database

Switch(vlan)#vlan 30 name Dosen

Switch(vlan)#vlan 40 name Mahasiswa

Switch(vlan)#vlan 50 name Karyawan

– Delegasikan port untuk mengakses tiap-tiap Vlan yang sudah didefinisikan :

Switch>enable

Switch#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#interface fa0/1 -> Menuju router

Switch(config-if)#switchport mode trunk

Switch(config-if)#exit

Switch(config)#interface fa0/2 -> Menuju PC Dosen

Switch(config-if)#switchport access vlan 30

Switch(config-if)#exit

Switch(config)#interface fa0/3 -> Menuju PC Mahasiswa

Switch(config-if)#switchport access vlan 40

Switch(config-if)#exit

Switch(config)#interface fa0/4 -> Menuju PC Karyawan

Switch(config-if)#switchport access vlan 50

Switch(config-if)#exit

– verifikasi vlan

Switch#show vlan

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

1    default                          active    Fa0/5, Fa0/6, Fa0/7, Fa0/8

                                                Fa0/9, Fa0/10, Fa0/11, Fa0/12

                                                Fa0/21, Fa0/22, Fa0/23, Fa0/24

30   dosen                            active    Fa0/2

40   mahasiswa                        active    Fa0/3

50   karyawan                         active    Fa0/4

Setting IP masing – masing PC :

- PC 0 :

IP Address………………….: 192.168.30.1

Subnet Mask…………………: 255.255.255.0

Default Gateway……………..: 192.168.30.254

- PC 1 :

IP Address………………….: 192.168.40.1

Subnet Mask…………………: 255.255.255.0

Default Gateway……………..: 192.168.40.254

- PC 2 :

IP Address………………….: 192.168.50.1

Subnet Mask…………………: 255.255.255.0

Default Gateway……………..: 192.168.50.254

– Test Ping ke router dan ke masing – masin pc :

PC>ipconfig
