开启telnet的几种方法

开启telnet方法一：需要VTY的密码和进入超级权限的密码（VTY虚拟终端，一种网络设备的连接方式）

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode password
Please configure the login password (maximum length 16):huawei
[R1-ui-vty0-4]qui
[R1]super password cipher abc123

<R2>telnet 192.168.1.1
<R1>super

开启telnet方法二：只需要VTY密码，不需要超级密码
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode password
Please configure the login password (maximum length 16):huawei
[R1-ui-vty0-4]user privilege level 3（提升用户权限，原先权限为0）

开启telnet方法三：通过用户名和密码进入vty，通过super密码进入超级权限
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa
[R1-ui-vty0-4]qui
[R1]super password cipher abc123
[R1]aaa
[R1-aaa]local-user abc password cipher 123
[R1-aaa]local-user abc service-type telnet
