VLAN

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.

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”.
