HCNA配置telnet远程管理

1、拓扑图

说明：通过配置最终能通过R5 用telnet协议登陆到R4上并将R4改名为R44

2、R4配置

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R4
[R4]user-in
[R4]user-interface vty
[R4]user-interface vty
[R4-ui-vty0-]au
[R4-ui-vty0-]authentication-mode aaa
[R4-ui-vty0-]q
[R4]aaa
[R4-aaa]lo
[R4-aaa]local-user user
[R4-aaa]local-user user-telnet pass
[R4-aaa]local-user user-telnet password ci
[R4-aaa]local-user user-telnet password cipher huawei
Info: Add a new user.
[R4-aaa]lo
[R4-aaa]local-user pri
[R4-aaa]local-user user
[R4-aaa]local-user user-telnet pri
[R4-aaa]local-user user-telnet privilege le
[R4-aaa]local-user user-telnet privilege level
[R4-aaa]loc
[R4-aaa]local-user user
[R4-aaa]local-user user-telnet serv
[R4-aaa]local-user user-telnet service-type tel
[R4-aaa]local-user user-telnet service-type telnet

[R4-aaa]
[R4-aaa]q
[R4]int
[R4]interface g
[R4]interface GigabitEthernet //

[R44]

3、R5配置并进行测试

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R5
[R5]int
[R5]interface g
[R5]interface GigabitEthernet //
[R5-GigabitEthernet0//]ip add
[R5-GigabitEthernet0//]ip address 192.168.1.20
Dec    ::-: R5 %%01IFNET//LINK_STATE(l)[]:The line protocol IP
on the interface GigabitEthernet0// has entered the UP state.
[R5-GigabitEthernet0//]q
[R5]dis ip in
[R5]dis ip interface bri
[R5]dis ip interface brief
*down: administratively down
^down: standby
(l): loopback
(s): spoofing
The number of interface that is UP in Physical is
The number of interface that is DOWN in Physical is
The number of interface that is UP in Protocol is
The number of interface that is DOWN in Protocol is

NULL0                             unassigned           up         up(s)

注意：telnet只能在用户模式上用

创建用户步骤

1、system-view进入系统模式

2、user-interface vty  0 4 进入vty视图

3 、允许AAA授权，退出vty

4、进入AAA模式 进入AAA视图

5、添加用户 local-user user-telnet password ciper huawei

6、授权用户级别2+ local-user user-telnet privileges level 2

7、授权用户可用协议  local-user user-telnet  service-type telnet

8、退出

9、从另外一台路由器登陆测试，前提是IP配置好互相能ping 通
