21、名为“虚拟局域网”，VLAN 是一种将局域网设备从逻辑上划分（注意，不是从物理上划分）成一个网段，从而实现虚拟工作组的数据交换技术；VLAN 的优点有：增加了网络连接的灵活性；控制网络上的广播；增加网络的安全性。2、初始状态所有的端口都在default 中(实际就是 vlan 1)，所有的端口都可以连通。划分后，将交换机端口划分到不同的VLAN 中，同一个VLAN 中的主机可以互相连通，不同VLAN中的主机不能联通，可以有效控制网络上的广播。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 5 页，共 5 页 - - - - - - - - -
