MAC地址表

1.1.1 MAC 地址表项的生成方式
MAC 地址表项的生成方式有两种：自动生成、手工配置。 1. 自动生成 MAC 地址表项一般情况下，MAC 地址表是设备通过源 MAC 地址学习过程而自动建立的。设备学习 MAC 地址的方法如下：如果从某接口（假设为接口 A）收到一个数据帧，设备就会分析该数据帧的源 MAC 地址（假设为 MAC-SOURCE），并认为目的 MAC 地址为 MAC-SOURCE 的报文可以由接口 A 转发；如果 MAC 地址表中已经包含 MAC-SOURCE，设备将对该表项进行更新；如果 MAC 地址表中尚未包含 MAC-SOURCE，设备则将这个新 MAC 地址以及该 MAC 地址对应的接口 A 作为一个新的表项加入到 MAC 地址表中。为适应网络的变化，MAC 地址表需要不断更新。MAC 地址表中自动生成的表项并非永远有效，每一条表项都有一个生存周期，到达生存周期仍得不到刷新的表项将被删除，这个生存周期被称作老化时间。如果在到达生存周期前纪录被刷新，则该表项的老化时间重新计算。 2. 手工配置 MAC 地址表项设备通过源 MAC 地址学习自动建立 MAC 地址表时，无法区分合法用户和黑客用户的报文，带来了安全隐患。如果黑客用户将攻击报文的源 MAC 地址伪装成合法用户的 MAC 地址，并从设备的其它接口进入，设备就会学习到错误的 MAC 地址表项，于是就会将本应转发给合法用户的报文转发给黑客用户。为了提高接口安全性，网络管理员可手工在 MAC 地址表中加入特定 MAC 地址表项，将用户设备与接口绑定，从而防止假冒身份的非法用户骗取数据。手工配置的 MAC 地址表项优先级高于自动生成的表项。

MAC地址表（交换机）、ARP缓存表以及路由表（路由器）

MAC地址表（交换机）、ARP缓存表以及路由表（路由器）⼀、MAC地址表详解说到MAC地址表，就不得不说⼀下交换机的⼯作原理了，因为交换机是根据MAC地址表转发数据帧的。

在交换机中有⼀张记录着局域⽹主机MAC地址与交换机接⼝的对应关系的表，即为MAC地址表，交换机就是根据这张表负责将数据帧传输到指定的主机上的。

交换机的⼯作原理交换机在接收到数据帧以后，⾸先会记录数据帧中的源MAC地址和对应的接⼝到MAC表中，接着会检查⾃⼰的MAC表中是否有数据帧中⽬标MAC地址的信息，如果有则会根据MAC表中记录的对应接⼝将数据帧发送出去(也就是单播)，如果没有，则会将该数据帧从⾮接受接⼝发送出去(也就是⼴播)。

下图为数据经过单交换机的传输过程。

单交换机数据交换⽰意图 1)主机A会将⼀个源MAC地址为⾃⼰，⽬标MAC地址为主机B的数据帧发送给交换机。

2)交换机收到此数据帧后，⾸先将数据帧中的源MAC地址和对应的接⼝(接⼝为f 0/1) 记录到MAC地址表中。

3)然后交换机会检查⾃⼰的MAC地址表中是否有数据帧中的⽬标MAC地址的信息，如果有，则从MAC地址表中记录的接⼝发送出去，如果没有，则会将此数据帧从⾮接收接⼝的所有接⼝发送出去(也就是除了f 0/1接⼝)。

4)这时，局域⽹的所有主机都会收到此数据帧，但是只有主机B收到此数据帧时会响应这个⼴播，并回应⼀个数据帧，此数据帧中包括主机B的MAC地址。

如果没有主机相应这个⼴播，则会继续向下⼀个交换机或路由器传播。

5)当交换机收到主机B回应的数据帧后，也会记录数据帧中的源MAC地址(也就是主机B的MAC地址)，这时，再当主机A和主机B通信时，交换机根据MAC地址表中的记录，实现单播了。

下图为经多个交换机进⾏数据传播的过程。

经多个交换机数据传播的过程 1)主机A将⼀个源MAC地址为⾃⼰、⽬标MAC地址主机C的数据帧发送给交换机。

2)交换机1收到此数据帧后，会解析源MAC地址，并检查MAC地址表，发现没有⽬标MAC地址的记录，则会将数据帧⼴播出去，主机B和交换机2都会收到此数据帧。

交换机MAC地址表

交换机MAC地址表交换机在转发数据时，需要根据MAC 地址表来做出相应转发，如果目标主机的MAC 地址不在表中，交换机将收到的数据包在所有活动接口上广播发送。

当交换机上的接口状态变成UP 之后，将动态从该接口上学习MAC 地址，并且将学习到的MAC 地址与接口相对应后放入MAC 地址表。

交换机的MAC 地址表除了动态学习之外，还可以静态手工指定，并且在指定MAC 地址时，还可以指定在某个VLAN 的某个接口收到相应的MAC 后，将数据包作丢弃处理。

注：交换机上，一个接口可以对应多个MAC 地址，地址的数量无上限，但不超过交换机所支持的MAC 地址最大数量。

一个MAC 地址可以同时出现在交换机的多个接口上，但此特性并不被所有型号的交换机支持，在某些型号的交换机上，一个MAC 地址只能出现在一个接口上，如果出现在另外一个接口上，将会报错，并且数据转发也会出错。

1.查看交换机MAC 地址表（1）查看接口F0/1 的MAC 地址表Switch#sh mac-address-table interface f0/1Mac Address Table-------------------------------------------Vlan Mac Address---- ----------- -------- -----0013.1a2f.0680 DYNAMIC Fa0/1TypePorts2Total Mac Addresses for this criterion: 1Switch#说明：交换机从F0/1 上学习到了MAC 地址0013.1a2f.0680，并且说明是动态学习到的。

2.手工静态指定MAC 地址（1）手工静态指定MAC 地址Switch(config)#mac-address-table static 0013.1a2f.0680 vlan 1 interface f0/2说明：指定VLAN 1 的接口F0/2 的MAC 地址为0013.1a2f.0680。

解决方案：配置交换机只学习动态mac地址，不学习静态mac地址，减少虚假mac地址的输入；启用mac 地址过滤功能，只允许已知的、合法的mac地址通过交换机端口；限制交换机端口的mac地址学习速率，防止短时间内学习大量虚假mac地址。
掌握从交换机mac地址表中删除条目的方法
详细描述
从交换机mac地址表中删除条目需要遵循一定的步骤和规则。首先需要确定要删除的条目，然后通过特定的命令将条目从mac地址表中删除。在删除过程中，需要注意命令的正确性和参数的设置。
mac地址表的绑定
总结词
了解如何将mac地址表中的条目与特定的IP 地址进行绑定
交换机在运行过程中会不断学习新的mac地址，当mac地址表达到上限时，会导致交换机性能下降甚至出现故障。因此，需要定期清理mac地址表，删除不再使用的或者无效的 mac地址条目。
限制mac地址表的容量
可以通过配置交换机的参数来限制mac地址表的容量，从而避免因mac地址表过大而导致的溢出问题。
使用动态mac地址绑定
总结词
交换机MAC地址表频繁变化或丢失
详细描述
可能是由于网络中存在大量ARP欺骗攻击、MAC地址漂移等问题，导致交换机MAC地址表频繁变化或
丢失。
解决方案
配置交换机端口安全功能，绑定MAC地址与端口，防止ARP欺骗攻击；使用静态MAC地址表，避免MAC 地址漂移问题；定期检查网络设备日志，发现异常
及时处理。

37张图详解MAC地址、以太网、二层转发、VLAN

37张图详解MAC地址、以太网、二层转发、VLANMAC 地址每个网卡或三层网口都有一个MAC 地址，MAC 地址是烧录到硬件上，因此也称为硬件地址。

MAC 地址作为数据链路设备的地址标识符，需要保证网络中的每个MAC 地址都是唯一的，才能正确识别到数据链路上的设备。

MAC 地址由6 个字节组成。

前3 个字节表示厂商识别码，每个网卡厂商都有特定唯一的识别数字。

后3 个字节由厂商给每个网卡进行分配。

厂商可以保证生产出来的网卡不会有相同MAC 地址的网卡。

现在可以通过软件修改MAC 地址，虚拟机使用物理机网卡的MAC 地址，并不能保证 MAC 地址是唯一的。

但是只要 MAC 地址相同的设备不在同一个数据链路上就没问题。

为了查看方便，6 个字节的MAC 地址使用十六进制来表示。

每个字节的 8 位二进制数分别用 2 个十六进制数来表示，例如我的网卡MAC 地址是 E0-06-E6-39-86-31。

什么是字节？什么是比特？比特，英文名bit，也叫位。

二进制中最小单位，一个比特的值要么是 0 要么是 1 。

字节，英文名Byte。

一个字节由八个比特构成。

MAC 地址怎么使用？最常用的以太网和无线局域网，都是使用MAC 地址作为地址标识符进行通信的。

以太网有线局域网中普遍使用以太网，以太网标准简单，传输速率高。

常见的网络拓扑结构如下图。

什么是网络拓扑？网络的连接和构成的形态称为网络拓扑。

它不仅可以直观的看到网络物理连接方式，还可以表示网络的逻辑结构。

以太网数据格式当今最常用的以太网协议标准是 ETHERNET II 标准。

ETHERNET II 标准定义的数据帧格式如下图。

•前导码（ Preamble ）前导码由 7 个字节组成，每个字节固定为 10101010 。

之后的 1 个字节称为帧起始定界符，这个字节固定为 10101011 。

这 8 个字节表示以太网帧的开始，也是对端网卡能够确保与其同步的标志。

帧起始定界符的最后两位比特被定义为 11 ，之后就是以太网数据帧的本体。

MAC地址详解

MAC(Media Access Control)地址，或称为MAC位址、硬件位址，用来定义网络设备的位置。

在OSI模型中，第三层网络层负责IP地址，第二层资料链结层则负责MAC位址。

因此一个主机会有一个IP地址，而每个网络位置会有一个专属于它的MAC位址。

以路由器来说，假设现有一台路由器，含有一个WAN埠及四个LAN埠。

它的WAN埠会有一个如61.61.61.61的IP地址，也会有一个如01:0A:02:0B:03:0C 的MAC位址。

而它的四个LAN埠，会共用一个例如192.168.1.1这样的IP地址，但是四个埠各会有一个不同的MAC位址。

再以交换器来说，它没有IP地址，但每个交换器的埠都会有一个不同的MAC位址。

[1]基本格式MAC位址共48位元（6个字节），以十六进制表示。

广播位址为ff:ff:ff:ff:ff:ff。

后24位元由IEEE等各组织决定如何分配，前24位元由实际生产该网络设备的厂商自行指定。

作用原理00000000部分就是修改网卡MAC地址的部分MAC地址就是网卡的标识，相当于人的身份证一样，MAC地址是写入网卡ROM内的，所以不管你的网卡装在那台机器上，你的MAC地址都是唯一的。

什么是MAC地址？我们该怎么去理解MAC地址呢？我们首先来理解一下IP地址和MAC地址之间的关系：在日常的计算机使用过程中，大家都知道IP地址只要规划合理，你可以任意更改IP地址。

修改的方法也是比较简单的，只要在对应网卡的TCP/IP协议上双击一下然后修改参数就行了。

那么MAC地址与IP地址同为地址，它们之间有什么地方相似又有什么地方不同呢？下面就让我们一起来看看吧，了解它们的差异与类似之处便于我们更好的掌握。

在OSI(Open System Interconnection，开放系统互连)7层网络协议参考模型中，第二层为数据链路层(Data Link)。

MAC地址也叫物理地址、硬件地址或链路地址，由网络设备制造商生产时写在硬件内部。
