请问怎样进行交换机化分VLAN啊？

Switch>en
Switch#vlan database
Switch(vlan)#vlan 1 name sales
A default VLAN may not have its name changed.
Switch(vlan)#vlan 2 name sales
VLAN 2 added:
Name: sales
Switch(vlan)#vlan 3 name marketing
VLAN 3 added:
Name: marketing
Switch(vlan)#vlan 4 name mis
VLAN 4 added:
Name: mis
Switch(vlan)#exit
APPLY completed.
Exiting....

将指定接口放入你想要的VLAN
Switch(config)#int f 0/1
Switch(config-if)#switchport access vlan 2
Switch(config-if)#int f 0/2
Switch(config-if)#switchport access vlan 3
Switch(config-if)#int f 0/3
Switch(config-if)#switchport access vlan 4
Switch(config-if)#^Z

根据实际情况自己改变..
以上为CISCO产品命令

看你的交换机什么牌子，什么型号啊。
先vlan datebase **
把接口与VLAN关联。。
