需求： PC机客户端通过SSH能够远程登录交换机进行远程管理。

步骤一,生成本地密钥对：

[test]rsa local-key-pair create 
The key name will be: Auotnavi-callcenter-01_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 = 512]:1024 
Generating keys… 
.++++++ 
…………++++++ 
……………++++++++ 
.++++++++

步骤二，配置VTY用户界面：

[Auotnavi-callcenter-01]user 
[Auotnavi-callcenter-01]user-in 
[Auotnavi-callcenter-01]user-interface vty 0 4 
[Auotnavi-callcenter-01-ui-vty0-4]auth 
[Auotnavi-callcenter-01-ui-vty0-4]authentication-mode aaa 
[Auotnavi-callcenter-01-ui-vty0-4]pro 
[Auotnavi-callcenter-01-ui-vty0-4]protocol in 
[Auotnavi-callcenter-01-ui-vty0-4]protocol inbound ssh

步骤三，创建SSH用户及密码

#aaa

#local-user root password simple 123456 
#local-user root privilege level 3 
#local-user root service-type ssh

步骤四，使用stelnet:

[test]stelnet server enable 
Info: Succeeded in starting the Stelnet server.

[test]ssh authentication-type default password
