Packet Tracer 5.0实验(二) 交换机的Telnet远程登录设置

一、实验目标
掌握采用telnet方式配置交换机的方法

二、技术原理

配置交换机的管理IP地址(计算机的IP地址与交换机管理IP地址在同一网段)；

为telnet用户配置用户名和登录口令：

Switch(config)#enble password xxxx //设置进入特权模式的密码；
Switch(config-line)#password xxxx //可以设置通过console端口连接设备及telnet远程登录时所需要的密码。
Switch(config)#line console 0
Switch(config-line)#password xxxx //设置通过console端口连接设备的密码
Switch(config-line)#login
Switch(config)#line vty 0 4
Switch(config-line)#password xxxx //设置telnet远程登录密码
Switch(config-line)#login

三、实验步骤
实验拓扑



Switch>en
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
1、配置交换机的管理IP地址
Switch(config)#interface vlan 1 //默认情况下交换机所有端口都处于 vlan 1 当中
Switch(config-if)#ip address 192.168.1.1 255.255.255.0 //配置交换机管理IP地址
Switch(config-if)#no shutdown //开启Interface Vlan1

%LINK-5-CHANGED: Interface Vlan1, changed state to up

Switch(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

Switch(config-if)#exit
2、设置进入特权模式的密码
Switch(config)#enable password 123456 //设置进入特权模式的密码
Switch(config)#line console ?
<0-0> First Line number
3、设置通过console端口连接设备的密码
Switch(config)#line console 0
Switch(config-line)#password asdf //设置通过console端口连接设备的密码
Switch(config-line)#login
Switch(config-line)#exit
Switch(config)#line vty ?
<0-15> First Line number
4、设置telnet远程登录密码
Switch(config)#line vty 0 4
Switch(config-line)#password abc123 //设置telnet远程登录密码
Switch(config-line)#login
Switch(config-line)#end
Switch#
%SYS-5-CONFIG_I: Configured from console by console

5、查看配置情况
Switch#show running-config

end

Switch#

四、验证
1、验证通过console端口连接设备的密码
Press RETURN to get started.

User Access Verification

Password: //这里输入asdf
Switch>
2、验证进入特权模式的密码
Switch>en
Password: //这里输入123456
Switch#
3、验证telnet远程登录密码
a. 给PC机设置IP地址



b. 打开Command Prompt
Packet Tracer PC Command Line 1.0
PC>ipconfig

IP Address......................: 192.168.1.2
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 192.168.1.1

PC>ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:

Request timed out.
Reply from 192.168.1.1: bytes=32 time=32ms TTL=255
Reply from 192.168.1.1: bytes=32 time=32ms TTL=255
Reply from 192.168.1.1: bytes=32 time=31ms TTL=255

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),
Approximate round trip times in milli-seconds:
Minimum = 31ms, Maximum = 32ms, Average = 31ms

PC>telnet 192.168.1.1 //远程登录
Trying 192.168.1.1 ...Open

User Access Verification

Password: //vty密码
Switch>en
Password: //enable密码
Switch#show running-config
