31 Switch#vlan database 

32 % Warning: It is recommended to configure VLAN from config mode,

33   as VLAN database mode is being deprecated. Please consult user

34   documentation for configuring VTP/VLAN in config mode.

35 

36 Switch(vlan)#vlan 2

37 VLAN 2 added:

38     Name: VLAN0002

39 Switch(vlan)#vlan 3

40 VLAN 3 added:

41     Name: VLAN0003

 第二步：建立vlan trunk

Switch# configure terminal 

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

Switch(config)#int fa0/1

Switch(config-if)#switchport mode trunk

 

第三步：将相应的端口添加到相应的vlan
