HCNA-3 通过配置Telnet登录系统
HCNA-3 通过配置Telnet登录系统利用Router2和Router3模拟PC通过Telnet远程访问Router1设备；2为普通用户给予监控权，3为管理员给予最高管理权限。1、基本配置Router1<Huawei>clocktimezone BJ add 8:00:00<Huawei>clockdatetime 22:30 2020-04-13<Huawei>system-viewsysnameRouter1headerlogin information "welcome to ipgzj.com"//配置登录时标题文本信息为headershell information "welcome to zurkj.com"//配置登录成功后标题文本信息为interfaceGigabitEthernet 0/0/0ipaddress 10.1.1.1 24quitdisplayip interface briefreturn<Router1>saveRouter2<Huawei>system-viewsysnameRouter2interfaceGigabitEthernet 0/0/0ipaddress 10.1.1.100 24return<Router2>displayip interface brief<Router2>saveRouter3<Huawei>system-viewsysnameRouter3interfaceGigabitEthernet 0/0/0ipaddress 10.1.1.200 24return<Router3>displayip interface brief<Router3>save
2、配置Telnet密码验证Router1<Router1>system-viewuser-interfacevty 0 4//VTY用户界面authentication-modepassword //认证模式为密码Please configurethe login password (maximum length 16):admin1234//配置密码：return<Router1>save在Router2与Router3上Telnet连接Router1（系统默认给予权限）<Router2>telnet10.1.1.1 //远程登录Press CTRL_] to quit telnet modeTrying 10.1.1.1 ...Connected to 10.1.1.1 ...Loginauthentication //登录认证Password:<Router1>
3、配置Telnet区分不同用户的权限<Router1>system-viewuser-interfacevty 0 4authentication-modepasswordPlease configurethe login password (maximum length 16):admin1234setauthentication password cipher admin1234 （另一种配置密码的方式）userprivilege level 15//配置用户权限 级别15return<Router1>save在Router2与Router3上Telnet连接Router1（配置级别为15的管理员权限）<Router2>telnet10.1.1.1Press CTRL_] to quit telnet modeTrying 10.1.1.1 ...Connected to 10.1.1.1 ...LoginauthenticationPassword:<Router1>displayusers//查看用户User-Intf Delay Type Network Address AuthenStatus AuthorcmdFlag0 CON0 00:01:33 pass Username : Unspecified+ 129 VTY 0 00:00:00 TEL 10.1.1.100 pass Username : Unspecified通过AAA视图配置一个user及zurkj扮演用户和管理员角色用户权限1；管理员15Router1<Router1>system-viewuser-interfacevty 0 4 //VTY用户界面authentication-modeaaa //认证模式 AAAquitlocal-userzurkj password cipher admin1234 //本地用户zurkj 密码 密文显示admin1234local-userzurkj privilege level 15 //本地用户zurkj权限级别 15local-userzurkj service-type telnet //本地用户zurkj服务类型Telnetlocal-useruser password cipher admin1234 privilege level 1 //密码和级别可同时配置local-useruser service-type telnetquitdisplaylocal-user //查看本地用户 ----------------------------------------------------------------------------User-name StateAuthMask AdminLevel ----------------------------------------------------------------------------user A T 1 admin A H - zurkj A T 15 ----------------------------------------------------------------------------Total 3 user(s)在Router2与Router3上Telnet连接Router1<Router2>telnet10.1.1.1Press CTRL_] to quit telnet modeTrying 10.1.1.1 ...Connected to 10.1.1.1 ...LoginauthenticationUsername:userPassword: -----------------------------------------------------------------------------User last login information: -----------------------------------------------------------------------------Access Type: Telnet IP-Address : 10.1.1.1 Time : 2020-04-13 20:38:43+08:00 -----------------------------------------------------------------------------<Router1>system-view//无权限报错 ^Error:Unrecognized command found at '^' position.
