交换机配置过程
一、本地配置方式本地配置我们首先要遇到的是它的物理连接方式，然后还需要面对软件配置，在软件配置方面我们主要以最常见的思科的“Catalyst 1900”交换机为例来讲述。
因为要进行交换机的本地配置就要涉及到硬、软件的连接了，所以下面我们分这两步来说明配置的基本连接过程。
1．物理连接因为笔记本电脑的便携性能，所以配置交换机通常是采用笔记本电脑进行，在实在无笔记本的情况下，当然也可以采用台式机，但移动起来麻烦些。
交换机的本地配置方式是通过计算机与交换机的“Console”端口直接连接的方式进行通信的，它的连接图如图1所示。
图1可进行网络管理的交换机上一般都有一个“Console”端口（这个在前面介绍集线器时已作介绍，交换机也一样），它是专门用于对交换机进行配置和管理的。
通过Console端口连接并配置交换机，是配置和管理交换机必须经过的步骤。
虽然除此之外还有其他若干种配置和管理交换机的方式（如Web方式、Telnet方式等），但是，这些方式必须依靠通过Console 端口进行基本配置后才能进行。
因为其他方式往往需要借助于IP地址、域名或设备名称才可以实现，而新购买的交换机显然不可能内置有这些参数，所以通过Console端口连接并配置交换机是最常用、最基本也是网络管理员必须掌握的管理和配置方式。
不同类型的交换机Console端口所处的位置并不相同，有的位于前面板（如Catalyst 3200和Catalyst 4006），而有的则位于后面板（如Catalyst 1900和Catalyst 2900XL）。
通常是模块化交换机大多位于前面板，而固定配置交换机则大多位于后面板。
不过，倒不用担心无法找到Console端口，在该端口的上方或侧方都会有类似“CONSOLE”字样的标识，如图2所示。
图2除位置不同之外，Console端口的类型也有所不同，绝大多数（如Catalyst 1900和Catalyst 4006）都采用RJ－45端口（如图2所示），但也有少数采用DB－9串口端口（如Catalyst 3200）或DB－25串口端口（如Catalyst 2900）。

华为镜像配置说明及配置实例
华为镜像说明端口镜像详解什么是端口镜像?把交换机一个或多个端口（VLAN）的数据镜像到一个或多个端口的方法。
为什么需要端口镜像 ?通常为了部署 IDS 产品需要监听网络流量（网络分析仪同样也需要），但是在目前广泛采用的交换网络中监听所有流量有相当大的困难，因此需要通过配置交换机来把一个或多个端口（VLAN）的数据转发到某一个端口来实现对网络的监听。
端口镜像的别名支持端口镜像的交换机大多数中档以上的交换机都支持端口镜像功能，但支持程度不同。
端口镜像配置方法下面是几种交换机的端口镜像配置方法，主要来自于 Talisker Security Wizardry (/) 的 Switch Port Mirroring (/switch.htm)Cisco 交换机特点：Cisco 2900 和 Cisco 3500XL 系列交换机Cisco 2950、Cisco 3550 和 Cisco 3750 系列交换机Cisco catylist 2550 Cisco catylist 3550 支持2组monitor session en password config term Switch(config)#monitor session 1 destination interface fast0/4（1为session id，id范围为1－2） Switch(config)#monitor session 1 source interface fast0/1 , fast0/2 , fast0/3 (空格，逗号，空格) Switch(config)#exit Switch#copy running-conf startup-conf Switch#show port-monitorCisco 5000 系列交换机使用 CatOS 的 Cisco 4000 和 Cisco 6000 系列交换机使用 IOS 的 Cisco 4000 和 Cisco 6000 系列交换机Extreme 交换机特点：●只能创建多对一或者一对一的镜像端口●可以监听 VLAN 的流量●Extreme 会镜像 IN 和 OUT 的流量。

The software version number can be seen from parameter 640 Software version no.■High voltagewarningThe voltage of the frequency converteris dangerous whenever the converter isconnected to mains.Incorrect fitting of the motor or frequency converter may cause damage to the equipment,serious injury or death.Consequently,it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.■These rules concern your safety1.The frequency converter must be disconnectedfrom the mains if repair work is to be carriedout.Check that the mains supply has beendisconnected and that the prescribed time haspassed before removing motor and mains plugs.2.The[STOP/RESET]key on the control panel ofthe frequency converter does not disconnectthe equipment from mains and is thus not tobe used as a safety switch.3.The unit must be properly connected to theearth,the user must be protected against thesupply voltage and the motor must be protectedagainst overloading pursuant to prevailingnational and local regulations.4.The earth leakage currents are higher than3.5mA.5.Protection against motor overload is not includedin the factory setting.If this function is required,set parameter128Motor thermal protection todata value ETR trip or data value ETR warning.Forthe North American market:The ETR functionsprovide overload protection of the motor,class20,in accordance with NEC.6.Do not remove the plugs for the motor-and mainssupply while the frequency converter is connectedto mains.Check that the mains supply has beendisconnected and that the prescribed time haspassed before removing motor and mains plugs.7.Note that the frequency converter has more voltageinputs than L1,L2and L3when the DC busterminals are used.Check that all voltage inputsare disconnected and that the prescribed time haspassed before repair work is commenced.■Warning against unintended start1.The motor can be brought to a stop by meansof digital commands,bus commands,referencesor a local stop,while the frequency converteris connected to mains.If personal safetyconsiderations make it necessary to ensurethat no unintended start occurs,these stopfunctions are not sufficient.2.While parameters are being changed,themotor may start.Consequently,the stop key[STOP/RESET]must always be activated,following which data can be modified.3.A motor that has been stopped may start if faultsoccur in the electronics of the frequency converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.■■inputs only be voltage[START]■In order to enter the Menu mode [QUICK MENU]+[+]must be activated at the same time.In Menu mode,most of the frequency converter parameters can be changed.Scroll

设置交换机的侦听口以监视网络会话
设置交换机的侦听口以监视网络会话以前公司里用HUB的时候，可是非常幸福哦，我随便开一个IRIS就能监视整个公司里的网络数据包，能很方便和清楚的看到大家都在做什么，简直就是没有秘密可言了。
后来玩IDS测试SESSIONW ALL的时候我用URL的预先阻断功能，就能做到想黑那里就黑那里的假像，后来很多人纷纷效仿把公司网络简直搞的是一团糟糕。
总结一下就是基于HUB的网络安全性能实在是非常低，而且几乎没有什么可管理性。
如果您正在筹划一个新的网络结构，我强烈建议采用交换机代替HUB来实现（当然费用的差距也必须考虑）。
采用交换机的网络基本上就没有可被监听的危险了，但是前提就是交换机也必须好好配置和管理，否则把买来的设备用默认状态摆在那里也是很危险的。
还是以我们公司为例子好了。
我们用的是3COM的3300的交换机24口的那种，我简单的把我的网络接口配置成了一个侦听接口，还是可以轻松的监听整个网络的数据包，下面简单的介绍下步骤。
说明下就是现在的网络监视软件如IDS和信息审计系统等等都是需要把自己的网络接口在交换机上设置为侦听口的，否则是没有办法正常监视网络流量的。
首先是用串口从后面接上交换机给设备设置一个IP地址，这个可以随便设置当然和我们在一个网段是最方便的了。
然后默认情况下3COM的WEB服务就是打开的我们可以用IE登陆上去。
默认的口令和用户名我们可以用：security 登陆这是3COM设备的一个默认管理帐号，很多人都没有改有意思的是我在互联网上用SNMP扫描找到的3COM交换机99%用这个帐号都可以进去。
简单易用，功能还很强大，听说4400更厉害可惜还没有用过。
我们点击左面的configuration选项，再从右边出来界面中选择Roving AnalysisPort。
这个界面就是配置交换机侦听口的地方了。
当然你如果实现知道自己的网络接口接在交换机那个口上就比较方便可以直接配置了，如果你不知道的话可以点击Advanced Stack Setup这里来查看当前IP地址和交换机端口的对应关系。

旁路监控、串联监控，镜像模式
旁路监控、串联监控，镜像模式旁路监控和串联监控的⽐较常见的⽹络监控模式可以分为两种：⼀种是串联监控模式，另⼀种是旁路监控模式。
旁路模式⼀般是指通过交换机等⽹络设备的“端⼝镜像”功能来实现监控，在此模式下，监控设备只需要连接到交换机的指定镜像端⼝，所以形象的称之为“旁路监控”；⽽串联模式⼀般是通过⽹关或者⽹桥的模式来进⾏监控，由于监控设备做为⽹关或者⽹桥串联在⽹络中，所以称之为“串联监控模式”。
旁路模式和串联模式各有其优缺点，⽐较如下：[B]旁路模式的优点：[/B]1. 旁路监控模式部署起来⽐较灵活⽅便，只需要在交换机上⾯配置镜像端⼝即可。
不会影响现有的⽹络结构。
⽽串联模式⼀般要作为⽹关或者⽹桥，所以需要对现有⽹络结构进⾏变动。
2. 旁路模式分析的是镜像端⼝拷贝过来的数据，对原始传递的数据包不会造成延时，不会对⽹速造成任何影响。
⽽串联模式是串联在⽹络中的，那么所有的数据必须先经过监控系统，通过监控系统的分析检查之后，才能够发送到各个客户端，所以会对⽹速有⼀定的延时。
3. 旁路监控设备⼀旦故障或者停⽌运⾏，不会影响现有⽹络的正常原因。
⽽串联监控设备如果出现故障，会导致⽹络中断，导致⽹络单点故障。
[B]旁路模式的缺点：[/B]1. 需要交换机⽀持端⼝镜像才可以实现监控。
2. 旁路模式采⽤发送RST包的⽅式来断开TCP连接，不能禁⽌UDP通讯。
对于UDP应⽤，⼀般还需要在路由器上⾯禁⽌UDP 端⼝进⾏配合。
⽽串联模式不存在该问题。
3. 旁路模式不处理原始数据包，所以⽆法分配实时带宽。
关于如何在旁路模式下实现流量监控和局域⽹限速，不谈。
思科，华为等主流交换机镜像模式配置镜像模式⼤多数交换机都⽀持镜像技术，这可以对交换机进⾏⽅便的故障诊断。
我们称之为“mirroring ”或“Spanning ”。
端⼝镜像（Port Mirroring）可以让⽤户将所有的流量从⼀个特定的端⼝复制到⼀个镜像端⼝。
如果您的交换机提供端⼝镜像功能，则允许管理⼈员⾃⾏设置⼀个监视管理端⼝来监视被监视端⼝的数据。

Catalyst 2900 Series XL 配置手册
1.命令模式汇总
1.1 switch>
交换机处于用户命令状态，这时用户可以看交换机的连接状态，访问其它网络和主机，但不能看到和更改交换机的设置内容。
1.2 switch#
在Switch>提示符下键入enable，交换机进入特权命令状态Switch#，这时不但可以执行所有的用户命令，还可以看到和更改交换机的设置内容。
1.3 switch(vlan)#
使用该模式来配置指定Vlan的参数。
1.4 switch(config)#
使用该模式对交换机进行全局配置。
1.5 switch(config-if)#
使用该模式来配置以太端口的参数。
1.6 switch(config-line)#
使用该模式来配置terminal line的参数。
2具体配置说明
2.1建立Console端口连接
在第一次进行配置和将交换机接入网络前必须通过Console端口来进入交换机的CLI，对交换机进行配置。
在进入CLI后，通过命令enable进入到 privileged 模式。
2.2 设置密码
由于许多特权模式里的命令是用来设置系统参数，您应该设置密码来防止未经认证的使用。
2.3 配置telnet访问交换机
2.4 配置端口
2.4.1配置端口速度和双工模式
2.4.2在千兆以太端口配置Flow Control
2.5创建以太通道端口组
这些端口组作为一个独立的端口组用于交换机之间或交换机与服务器之间的高带宽连接。
可以在千兆口和百兆口创建端口组，但你不能创建包含两种端口速度的端口组。
IOS Release 12.0支持两种不同类型的端口组：基于源转发端口组和基于目的地转发端口组。
基于源转发端口组分散包转发到基于源地址的incoming包的组。
你可以在一个基于源转发端口组中配置8个端口。
基于源转发缺省时是开启的。
基于目的地端口组分散包转发到基于目的地址的incoming包的组。
你可以一个基于目的地址端口组中配置无限制数量的端口。
你可以一共创建12个基于源转发端口组、源于目的地转发端口组或者综合源、目的地端口。
在一个组中所有的端口必须是相同的类型：例如必须所有的都是基于源或所有的都是基于目的地。
你可以独立配置连接交换机的端口组，但在两端的配置必须一致。
以下限制应用于被转发到端口组的输入静态地址：
·如果端口组基于源地址转发（缺省），就配置静态地址转发到所有的端口组里面的端口。
这种方法限制丢包的可能。
·如果端口组基于目的地址转发，就配置静态地址只转发到端口组的一个端口。
这种方法
2.6配置flooding（控制开启一个网络端口）
每个Vlan指定一个网络端口可以减少网络里的广播交通量。
这时交换机转发未知目的地的地址到网络端口来代替广播到Vlan的所有端口。
2.7重加载或升级交换机软件
升级过程由以下步骤组成：
·将当前映像文件的名字改成新映像文件的名字，然后使用tar命令将旧的文件替换成新的文件。
·在你升级软件之前请关闭访问HTML文件的程序和删除存在的HTML文件，以避免在软件升级期间用户访问CVSM页面。
·升级完成后重新开启访问HTML文件的程序。
2.8配置IP信息
2.9创建和维护Vlan
一个端口可以属于这些模式：
·静态访问：端口属于一个VLAN。
·多重VLAN：端口属于多个VLAN。
2.9.1为Vlans指定静态访问端口
2.9.2指定端口到多个VLAN。
