simulasi vlan di cisco

Langkah-langkah:

1.      Buat skema jaringan seperti gambar diatas

2.      Konfigurasikan:

-                      PC0  :  192.168.5.10  gateway  :  192.168.5.1

-                      PC1  :  192.168.5.11  gateway  :  192.168.5.1

-                      PC2  :  192.168.6.10  gateway  :  192.168.6.1

-                      PC3  :  192.168.6.11  gateway  :  192.168.6.1

3.      Buka CLI pada switch dan konfigurasikan sbb:

Switch>enable Switch#vlan database % Warning: It is recommended to configure VLAN from config mode,   as VLAN database mode is being deprecated. Please consult user   documentation for configuring VTP/VLAN in config mode. Switch(vlan)#vlan 10 name a VLAN 10 modified:     Name: a Switch(vlan)#vlan 20 name b VLAN 20 modified:     Name: b Switch(vlan)#exit APPLY completed. Exiting.... Switch#conf t Enter configuration commands, one per line.  End with CNTL/Z. Switch(config)#int fa0/1 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 10 Switch(config-if)#int fa1/1 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 10 Switch(config-if)#int fa2/1 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 20 Switch(config-if)#int fa 3/1 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 20 Switch(config-if)#end %SYS-5-CONFIG_I: Configured from console by console Switch#config t Enter configuration commands, one per line.  End with CNTL/Z. Switch(config)#int fa4/1 Switch(config-if)#switchport mode trunk Switch(config-if)#end

1.      Kemudian konfigurasikan routernya:

Router>enable Router#conf t Enter configuration commands, one per line.  End with CNTL/Z. Router(config)#int fa0/0 Router(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up Router(config-if)#int fa0/0.1 %LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.1, changed state to up Router(config-subif)#int fa0/0.1 Router(config-subif)#encapsulation dot1q 1 Router(config-subif)#ip address 192.168.1.1 255.255.255.0 Router(config-subif)#int fa0/0.2 %LINK-5-CHANGED: Interface FastEthernet0/0.2, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.2, changed state to up Router(config-subif)#encapsulation dot1q 10 Router(config-subif)#ip address 192.168.5.1 255.255.255.0 Router(config-subif)#int fa0/0.3 %LINK-5-CHANGED: Interface FastEthernet0/0.3, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.3, changed state to up Router(config-subif)#encapsulation dot1q 20 Router(config-subif)#ip address 192.168.6.1 255.255.255.0 Router(config-subif)#end %SYS-5-CONFIG_I: Configured from console by console

Kesimpulan:

Untuk membuat VLAN harus melihat jumlah gateway yang berbeda, karena jumlah VLAN yang dibuat harus sama dengan jumlah gateway yang berbeda pada tiap pc didalam sebuah jaringan. Karena pada percobaan diatas gateway yang berbeda ada 2, yaitu 192.168.5.1 dan 192.168.6.1, maka jumlah VLAN yang dibuat juga harus 2. Pada simulasi diatas kedua VLAN tersebut diberi nama “VLAN 10 name a dan VLAN 20 name b”.
