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 0 4

 3、R5配置并进行测试

<Huawei>sys
Enter system view, return user view with Ctrl+Z.

[R5]interface g    
[R5]interface GigabitEthernet 0/0/0
[R5-GigabitEthernet0/0/0]ip add    
[R5-GigabitEthernet0/0/0]ip address 192.168.1.20 24

on the interface GigabitEthernet0/0/0 has entered the UP state.

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
