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
