实验一 路由器基本命令配置(基于Cisco Packet Tracer仿真实验).doc

实验一 路由器基本命令配置一、实验目的1、掌握路由器各种模式的切换；2、掌握路由器不同登陆方式口令的设置；3、掌握端口IP地址设置等常用命令的使用。二、 实验环境三、 实验步骤1、按照实验拓扑图，使用交叉网线连接PC1与路由器RTA的fa0/0端口。2、打开路由器RTA电源，启动路由器，观察路由器启动信息，提示是否进入系统配置对话框。System Bootstrap, Version 12.1(3r)T2, RELEASE SOFTWARE (fc1)Copyright (c) 2000 by cisco Systems, Inc.cisco 2621 (MPC860) processor (revision 0x200) with 60416K/5120K bytes of memorySelf decompressing the image :# OK Restricted Rights LegendUse, duplication, or disclosure by the Government issubject to restrictions as set forth in subparagraph(c) of the Commercial Computer Software - RestrictedRights clause at FAR sec. 52.227-19 and subparagraph(c) (1) (ii) of the Rights in Technical Data and ComputerSoftware clause at DFARS sec. 252.227-7013. cisco Systems, Inc. 170 West Tasman Drive San Jose, California 95134-1706Cisco Internetwork Operating System SoftwareIOS (tm) C2600 Software (C2600-I-M), Version 12.2(28), RELEASE SOFTWARE (fc5)Technical Support: /techsupportCopyright (c) 1986-2005 by cisco Systems, Inc.Compiled Wed 27-Apr-04 19:01 by miwangcisco 2621 (MPC860) processor (revision 0x200) with 60416K/5120K bytes of memory.Processor board ID JAD05190MTZ (4292891495)M860 processor: part number 0, mask 49Bridging software.X.25 software, Version FastEthernet/IEEE 802.3 interface(s)32K bytes of non-volatile configuration memory.63488K bytes of ATA CompactFlash (Read/Write) - System Configuration Dialog -Continue with configuration dialog? yes/no:实验结果分析：3、在路由器RTA上，输入no，并按回车键，进入路由器用户模式。Continue with configuration dialog? yes/no: noPress RETURN to get started!Router实验结果分析：4、在路由器RTA上，输入enable命令，由用户模式进入特权模式，输入exit命令，由特权模式退回到用户模式。Routerenable Router#exitRouter con0 is now availablePress RETURN to get started.Routerenable Router#实验结果分析：5、在路由器RTA上，输入configure terminal命令由特权模式进入全局配置模式，利用hostname命令将路由器的名称改为RTA。Router#configure terminal Enter configuration commands, one per line.
