第一台交换机switch1
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#vtp domain benet.com
Changing VTP domain name from NULL to benet.com
Switch(config)#vtp mode server
Device mode already VTP SERVER.
Switch(config)#vtp version 1
VTP mode already in V1.
Switch(config)#interface vlan 1
Switch(config-if)#ip address 172.16.0.1 255.255.0.0
Switch(config-if)#no shutdown
%LINK-5-CHANGED: Interface Vlan1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
Switch(config-if)#exit
这里为啥非要给VLAN 1设置个IP地址，不设置IP不行吗？能不能在原理上解释一下？谢谢各位

类似路由器，当然有个ip地址了

没有虚接口,VLAN怎么通信.
