1、创建rsa本地密钥对与创建账号
[Huawei]rsa local-key-pair create 

The key name will be: Huawei_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]:

2、华为交换机上面创建账号
aaa

local-user admin password cipher TKG40##Y,C!NZPO3JBXBHA!!

local-user admin privilege level 15

local-user admin service-type ssh

3、开启ssh服务以及ssh用户
stelnet server enable

ssh user admin

ssh user admin authentication-type password

ssh user admin service-type stelnet

4、VTY下添加设置
[Huawei]user-interface vty 0 4

[Huawei-ui-vty0-4]authentication-mode aaa

[Huawei-ui-vty0-4]protocol inbound ssh

5、配置实例

[Huawei] rsa local-key-pair create //创建rsa本地密钥对

[Huawei]aaa //进入aaa模式

[Huawei-aaa]local-user admin password ciper mima //配置登录用户密码(admin是登录用户名，mima是登录密码)

[Huawei-aaa]local-user admin service-type ssh //配置登录类型为SSH

[Huawei-aaa]quit //退出

[Huawei]user-interface vty 0 4 //配置用户虚拟端口

[Huawei-ui-vty0-4]authentication-mode aaa //认证类型为3a

[Huawei-ui-vty0-4]user privilege level 15 //配置用户级别

[Huawei-ui-vty0-4]protocol inbound ssh //配置允许ssh登入

[Huawei-ui-vty0-4]quit //退出

[Huawei]stelnet server enable //开启SSH服务

[Huawei]ssh user admin authentication-type password //配置admin用户设置ssh认证为password

[Huawei]ssh user admin service-type stelnet //配置admin用户设置ssh服务类型为stelnet

[Huawei]ssh server port 22622 //配置ssh登录端口为22622，默认是22
