命令行：
swA配置命令：
Switch>enable
Switch#vlan database //进入vlan配置模式
% 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 2 name TztA //在swA上创建vlan 2 名为TztA VLAN 2 added:
Name: TztA
Switch(vlan)#vlan 3 name TztB //在swA上创建vlan 3 名为TztB VLAN 3 added:
