　　註：IP地址與MAC地址的關系： IP地址是根據現在的IPv4標準指定的，不受硬件限制比較容易記憶的
地址，長度4個字節。而 MAC地址卻是用網卡的物理地址，保存在網卡的EPROM裏面，與硬件有關系，
比較難於記憶，長度為6個字節。
　　
　　雖然在TCP／IP網絡中，計算機往往需要設置IP地址後才能通訊，然而，實際上計算機之間的通訊並
不是通過IP地址，而是借助於網卡的MAC地址。IP地址只是被用於查詢欲通訊的目的計算機的MAC地址。
　　
　　ARP協議是用來向對方的計算機、網絡設備通知自己IP對應的MAC地址的。在計算機的　ARJ緩存中
包含壹個或多個表，用於存儲IP地址及其經過解析的以太網MAC地址。壹臺計算機與另壹臺IP地址的計算
機通訊後，在ARP緩存中會保留相應的MAC地址。所以，下次和同壹個IP地址的計算機通訊，將不再查詢
MAC地址，而是直接引用緩存中的MAC地址。
　　在交換式網絡中，交換機也維護壹張MAC地址表，並根據MAC地址，將數據發送至目的計算機。　
　（轉載註明出處n et130）
　　
　　為什麽要綁定MAC與IP 地址：IP地址的修改非常容易，而MAC地址存儲在網卡的EEPROM中，而且
網卡的MAC地址是唯壹確定的。因此，為了防止內部人員進行非法IP盜用(例如盜用權限更高人員的IP地
址，以獲得權限外的信息)，可以將內部網絡的IP地址與MAC地址綁定，盜用者即使修改了IP地址，也�
MAC地址不匹配而盜用失敗:而且由於網卡MAC地址的唯壹確定性，可以根據MAC地址查出使用該MAC
地址的網卡，進而查出非法盜用者。
　　
　　目前，很多單位的內部網絡，都采用了MAC地址與IP地址的綁定技術。下面我們就針對Cisco的交換
機介紹壹下IP和MAC綁定的設置方案。
　　
　　在Cisco中有以下三種方案可供選擇，方案1和方案2實現的功能是壹樣的，即在具體的交換機端口上綁
定特定的主機的MAC地址（網卡硬件地址），方案3是在具體的交換機端口上同時綁定特定的主機的MAC
地址（網卡硬件地址）和IP地址。
　　
　　1.方案1——基於端口的MAC地址綁定
　　
　　思科2950交換機為例，登錄進入交換機，輸入管理口令進入配置模式，敲入命令：
　　Switch#config terminal
　　＃進入配置模式
　　Switch(config)# Interface fastethernet 0/1
　　＃進入具體端口配置模式
　　Switch(config-if)#Switchport port-secruity
　　＃配置端口安全模式
　　Switch(config-if )switchport port-security mac-address MAC(主機的MAC地址)
　　＃配置該端口要綁定的主機的MAC地址
　　Switch(config-if )no switchport port-security mac-address MAC(主機的MAC地址)
　　＃刪除綁定主機的MAC地址
　　　　註意：
　　　　以上命令設置交換機上某個端口綁定壹個具體的MAC地址，這樣只有這個主機可以使用網絡，如果對
該主機的網卡進行了更換或者其他PC機想通過這個端口使用網絡都不可用，除非刪除或修改該端口上綁定的MAC地址，才能正常使用。
　　
　　註意：
　　
　　以上功能適用於思科2950、3550、4500、6500系列交換機
　　
　　2.方案2——基於MAC地址的擴展訪問列表
　　
　　Switch(config)Mac access-list extended MAC10
　　＃定義壹個MAC地址訪問控制列表並且命名該列表名為MAC10
　　Switch(config)permit host 0009.6bc4.d4bf any
　　＃定義MAC地址為0009.6bc4.d4bf的主機可以訪問任意主機
　　Switch(config)permit any host 0009.6bc4.d4bf
　　＃定義所有主機可以訪問MAC地址為0009.6bc4.d4bf的主機
　　Switch(config-if )interface Fa0/20
　　#進入配置具體端口的模式
　　Switch(config-if )mac access-group MAC10 in
　　＃在該端口上應用名為MAC10的訪問列表（即前面我們定義的訪問策略）
　　Switch(config)no mac access-list extended MAC10
　　＃清除名為MAC10的訪問列表
　　
　　此功能與應用壹大體相同，但它是基於端口做的MAC地址訪問控制列表限制，可以限定特定源MAC
地址與目的地址範圍。
　　
　　註意：
　　
　　以上功能在思科2950、3550、4500、6500系列交換機上可以實現，但是需要註意的是2950、3550需要交
換機運行增強的軟件鏡像（Enhanced Image）。
　　
　　3.方案3——IP地址的MAC地址綁定
　　
　　只能將應用1或2與基於IP的訪問控制列表組合來使用才能達到IP-MAC 綁定功能。
　　Switch(config)Mac access-list extended MAC10
　　＃定義壹個MAC地址訪問控制列表並且命名該列表名為MAC10
　　Switch(config)permit host 0009.6bc4.d4bf any
　　＃定義MAC地址為0009.6bc4.d4bf的主機可以訪問任意主機
　　Switch(config)permit any host 0009.6bc4.d4bf
　　＃定義所有主機可以訪問MAC地址為0009.6bc4.d4bf的主機
　　Switch(config)Ip access-list extended IP10
　　＃定義壹個IP地址訪問控制列表並且命名該列表名為IP10
　　Switch(config)Permit 192.168.0.1 0.0.0.0 any
　　＃定義IP地址為192.168.0.1的主機可以訪問任意主機
　　Permit any 192.168.0.1 0.0.0.0
　　＃定義所有主機可以訪問IP地址為192.168.0.1的主機
　　Switch(config-if )interface Fa0/20
　　#進入配置具體端口的模式
　　Switch(config-if )mac access-group MAC10 in
　　＃在該端口上應用名為MAC10的訪問列表（即前面我們定義的訪問策略）
　　Switch(config-if )Ip access-group IP10 in
　　＃在該端口上應用名為IP10的訪問列表（即前面我們定義的訪問策略）
　　Switch(config)no mac access-list extended MAC10
　　＃清除名為MAC10的訪問列表
　　Switch(config)no Ip access-group IP10 in
　　＃清除名為IP10的訪問列表
　　
　　上述所提到的應用1是基於主機MAC地址與交換機端口的綁定，方案2是基於MAC地址的訪問控制列
表，前兩種方案所能實現的功能大體壹樣。如果要做到IP與MAC地址的綁定只能按照方案3來實現，可根
據需求將方案1或方案2與IP訪問控制列表結合起來使用以達到自己想要的效果。
　　
　　註意：以上功能在思科2950、3550、4500、6500系列交換機上可以實現，但是需要註意的是2950、3550
需要交換機運行增強的軟件鏡像（Enhanced Image）。
　　
　　後註：從表面上看來，綁定MAC地址和IP地址可以防止內部IP地址被盜用，但實際上由於各層協議以
及網卡驅動等實現技術，MAC地址與IP地址的綁定存在很大的缺陷，並不能真正防止內部IP地址被盜用。

CCNA認證(CCNA-思科網絡安裝和支持認證助理)是整個Cisco認證體系中最初級的認證，同時它也是獲得CCNP認證、CCDP認證和CCSP認證的必要條件(CCIP認證、CCIE認證不強制要求)，而且許多Cisco專業認證(Cisco Qualified Specialist)也要求考生首先得CCNA認證。

壹、CCNA認證簡介

CCNA認證屬於Cisco售後工程師認證體系得入門認證，通過CCNA可以證明妳已掌握網絡得基本知識，並能初步安裝、配置和操作Cisco路由器、交換機及簡單的LAN和WAN。CCNA認證表示經過認證的人員具有為小型辦公室/庭辦公室(SOHO)市場聯網的基本技術和相關知識。通過CCNA認證的專業人員可以在小型網絡(100或100以下個節點)中安裝、配置和運行LAN、WAN和撥號訪問業務。他們可以使用的協議包括(但不限於)IP、IGRP、 IPX、Serial、Apple、Talk、Frame、Relay、IP RIP、VLAN RIP、Ethernet、Access Lists。

二、培訓技能

安裝、配置和操作簡單的路由局域網、路由廣域網，定義”簡單”網絡的內容，如IP、IGRP、IPX、串行、Apple、Talk、幀中繼、IP RIP、IPX RIP、VLAN、以太網和訪問到表等。

三、CCNA能夠根據培訓和現實世界的經驗提供解決方案：

1、安裝和/或配置壹個網絡;

2、通過利用訪問目錄過慮;

3、按需的帶寬(BOD)和按需撥號路由(DDR)等特性減少帶寬和降低廣域網成本的Internet訪問解決方案，優化廣域網。

4、通過集成撥號連接和傳統的遠程局域網到局域網訪問以及支持Internet電子商務和多媒體等新應用所需的最高水平的性能，提供

遠程訪問。

四、獲得CCNA認證的先決條件

不需要考生持有任何證書即可報考CCNA，同時對考生的年齡、學歷、外語水平均沒有硬性規定。

五、CCNA認證的考試

現在參加考試有：1、參加640-802CCNA

 640-802

六、CCNA認證的有效期

CCNA證書的有效期為三年，三年之後需要參加再認證(Recertification)的考試，如果妳再兩年內考取了更高級別的Cisco認證，則

CCNA認證的有效期自動更新。

七、CCNA的再認證考試

有效期滿之後必須參加640-811CND的考試，或者參加任何壹個CCNP、CCIP、CCSP、的考試，再或者參加Cisco專業認證(Cisco

Qualified Specialist)中任何壹顆前綴為642-XXX的考試。

八、CCNA認證目標

1.考完此課程後，考生將達到如下目標：

2.使用可用的配置工具完成設備初始化配置;

3.根據新需求，能夠通過增刪改等方式實現新功能;

4.使用命令行界面確定網絡性能和狀態;

5.根據給定的需求，實現接入層交換機配置;

6.使用命令行，實現VLAN、VTP、IEEEE802.1Q、ISL配置;

7.敘述靜態和動態路由協議(RIP、OSPF、IGRP、EIGRP)的功能和操作;

8.使用SHOW、DEBVG命令確定路由協議的異常;

9.能夠配置標準和擴展的訪問列表;

10.使用命令行接口配置串行接口(PPP、HDLC)。

Introduction
Welcome to CCNA! Recently Cisco Press came to me and told me, albeit very quietly, that
there was going to be some changes made to the CCNA certification exam, and asked
whether I would be interested in updating my CCNA Portable Command Guidefor release
around the time of the announcement of the new exam. I was already working on the various
command guides for the new CCNP certification exams, but I felt that a revision wouldn’t
take a lot of time, as hopefully there would still be a lot of concepts that hadn’t changed.
I have long been a fan of what I call the “Engineering Journal”—a small notebook that can
be carried around and that contains little nuggets of information—commands that you
forget, the IP addressing scheme of some remote part of the network, little reminders about
how to do something you only have to do once or twice a year (but is vital to the integrity
and maintenance of your network). This journal has been a constant companion by my side
for the past eight years; I only teach some of these concepts every second or third year, so
I constantly need to refresh commands and concepts and learn new commands and ideas as
they are released by Cisco. My journals were the best way for me to review because they
were written in my own words—words that I could understand. At least, I had better
understand them, because if I didn’t, I had only myself to blame.
The journals that I would create for my Academy classes would always be different from
the journals I would create when I was teaching from a different curriculum or if I was out
in the industry working on some production network. I could understand that the Academy
needed to split topics into smaller, more manageable chunks, but for me out in the real
world, I needed these concepts to follow a different approach—I needed all the routing
protocols together in one place in my journals, and not spread across some two-year outline
of knowledge.
This book is my “Industry” edition of the Engineering Journal. It contains a different logical
flow to the topics, one more suited to someone working in the field. Like topics are grouped
together: routing protocols, switches, troubleshooting. More-complex examples are given.
New topics have been added, such as IPv6, wireless, and the Security Device Manager
(SDM). The popular “Create Your Own Journal” appendix is still here—blank pages for
you to add in your own commands that you need in your specific job. We all recognize the
fact that no network administrator’s job can be so easily pigeonholed as to being just
working with CCNA topics—you all have your own specific jobs and duties assigned to
you. That is why you will find those blank pages at the end of the book—make this book
your own; personalize it with what you need to make it more effective. That way your
journal will not look like mine.
