vlan 只要是 L2 switch 就可以做得到 主要就是虛擬網段 切網段. 可以讓你規畫區網更好的方式 網段是否要互通 要看有沒有需求. 如果有此需求 那麼 L3 switch 有路由功能 自然就可以達到 vlan 又可以互通的功用. 舉例來說 公司部門不想互相存取資料. 你可以切vlan
You don’t use subinterfaces on a L3 switch. What you do is connect your L2 switch to your L3 switch via a L2 trunk. Then for each vlan you want to route on the 3750 you create a L3 SVI (switched virtual interface) eg. int vlan 10 ip address 192.168.5.1 255.255.255.0

Hi Vlans exist at layer 2. At layer 3 you have vlan interfaces. Vlan interfaces are only needed if you wanted to route between your vlans. So vlan 10 = 192.168.5.0/24 vlan 11 = 182.168.6.0/24 On a switch you create vlan 10 and vlan 11 at layer 2 only. Any PC
