1、创建本地RSA秘钥对
[BJDSNW-2F]rsa local-key-pair create //产生RSA本地秘钥
The key name will be: BJDSNW-2F_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.

2、配置vty界面支持的登录协议
[BJDSNW-2F]user-interface vty 0 4
[BJDSNW-2F-ui-vty0-4]authentication-mode aaa //验证方式为aaa
Warning: The level of the user-interface(s) will be the default level of AAA users, please check whether it is correct.
[BJDSNW-2F-ui-vty0-4]protocol inbound all {ssh | all} //这里选择ssh或者ALL都可以，ssh代表的是只支持ssh登录，all代表也支持其他的登录方式
//必须配置VTY用户界面的验证方式为AAA，不然protocol inbound ssh配置不成功
[BJDSNW-2F-ui-vty0-4]qu
3.
[BJDSNW-2F]ssh user admin // 创建SSH用户admin
