二、登录方式代码
要求：
1.console口进入操作界面必须接对口
2.HTTP登录时，登录名称是CISCO路由器名，密码是登录Telnet密码
3.Telnet登录必须在网卡网段与远方设备需同一网段
连线结构如右：
C3电脑绑定了实际物理网卡,在路由器没有设置Telnet时连线无效
Telnet设置:需要write后PC登录才能生效Router(config)#line vty 0 4Router(config-line)#pasRouter(config-line)#password ciscoRouter(config-line)#loginRouter(config-line)#exec-timeout 0 10 #0这个位置代表分钟 10这个位置代表秒钟--设置的都是光标退出时间PC输入，提示设置enable密码Router>en% No password set.回路由器输入下列代码Router(config)#enable password 123 ##注意secret的密码优先级比password密码优先级高，并且show run查询的时候在前面Router(config)#do write下面是PC输入的反馈信息pc>telnet 1.1.1.1Password: Password: Router>enPassword: Router#confConfiguring from terminal, memory, or network [terminal]? Enter configuration commands, one per line. End with CNTL/Z.Router(config)#Telnet设置成功
HTTP设置方式
HTTP设置 config ip http server ip domain www.cisco.com HTTP网页登录成功
用户名输入命令行中的用户名R1 密码输入telnet的密码
console口设置方式
Router(config)#line console 0Router(config-line)#password ciscoRouter(config-line)#login console密码设置成功
