分析 VLAN 技术概念及划分方法
一、 VLAN 技能概述
A, VLAN skills summary
VLAN(Virtual Local Area Network) 也就是虚拟局域
网,是一种建立在交流技能根底之上的, 经过将局域网内
的机器设备逻辑地而不是物理地区分红一个个不一样的
网段,以软件办法完成逻辑作业组的区分和办理的技能。
VLAN 的作用是使得同一 VLAN 中的成员间能够彼此通
讯,而不一样 VLAN 之间则是彼此阻隔的, 不一样的 VLAN
间的若是要通讯就要经过必要的路由设备。
VLAN ( Virtual Local Area Network ) is a virtual local
area network, is a kind of built on the foundation of
communication skills, after the equipment will be LAN
logical rather than physical area into a different network
segment, complete the distinction between logical
operations group in software way and management
skills. The role of VLAN is to make the members in the
same VLAN can communicate with each other, and not
the same between VLAN is another barrier, not the
same between VLAN if communication is about to pass
routing equipment necessary.
二、 VLAN 的长处
Two, the strengths of VLAN
(一)能够操控网络播送
( a ) to be able to control the network broadcast
在没有运用 VLAN 技能的局域网内的整个网络都是
播送域, 这样就使得网内的一台设备宣布网络播送时, 在
局域网内的任何一台设备的接口都能接收到播送, 因而当
网络内的设备越来越多时,网络上的播送也就越来越多,
占用的时刻和资源也就越来越多, 当播送多到必定的数量
时,就会影响到正常的信息的传送。 这样就能致使信息推
迟,严峻的能够形成网络的瘫痪、 阻塞, 严峻的影响了正
常的网络运用,这就是所谓的网络风暴。
In the absence of the use of VLAN skills LAN the entire
network are broadcast domain, which makes a device
within the network announced that the network
broadcast, any equipment in the LAN interface can
receive the broadcast, so when the e
