1、创建本地密钥对

[Core-SW]rsa local-key-pair create
The key name will be: Core-SW_Host
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
it will take a few minutes.
Input the bits in the modulus[default = 2048]:
Generating keys…
…+++++
…++
…++++
…++

2、检查是否存在SSH user（可跳过），系统提示没有SSH user 存在

[Core-SW]dis ssh user-information
Info: No SSH user exists.

3、创建SSH user

[Core-SW]ssh user test \可以直接敲第二行命令
[Core-SW]ssh user test authentication-type password \认证模式为密码认证
[Core-SW]ssh user test service-type stelnet \服务类型为stelnet，即SSH

4、创建用户

[Core-SW]aaa
[Core-SW-aaa]local-user test password cipher xxx（xxx处为你想要设置的密码)
Info: Add a new user.
[Core-SW-aaa]local-user test privilege level 3 \用户level最高到15
[Core-SW-aaa]local-user test service-type ?
8021x 802.1x user
bind Bind authentication user
ftp FTP user
http Http user
ppp PPP user
ssh SSH user
telnet Telnet user
terminal Terminal user
web Web authentication user
x25-pad X25-pad user
[Core-SW-aaa]local-user test service-type ssh \开启该用户允许使用SSH访问设备的权限

5、启用SSH（stelnet）服务

[Core-SW]stelnet server enable
Info: Succeeded in starting the Stelnet server.

6、配置vty界面支持的登录协议

[Core-SW]user-interface vty 0 4
[Core-SW-ui-vty0-4]authentication-mode aaa
[Core-SW-ui-vty0-4]protocol inbound ssh
