1.3 端口映射设置

选择入端口编号和出端口编号，勾选双向通道，点击增加

2. 交换机配置

2.1 配置vlanif

<Huawei>system-view 
[Huawei]sysname SWA
[SWA]interface Vlanif 1
[SWA-Vlanif1]ip address 192.168.83.135 24
[SWA-Vlanif1]q

2.2 配置vty

[SWA]user-interface vty 0 4
[SWA-ui-vty0-4]authentication-mode aaa
[SWA-ui-vty0-4]user privilege level 15
[SWA-ui-vty0-4]protocol inbound all 
[SWA-ui-vty0-4]q

2.3 配置ssh用户

[SWA]stelnet server  enable  
Info: Succeeded in starting the Stelnet server.
[SWA]ssh user sshadmin
[SWA]ssh user sshadmin authentication-type password
[SWA]ssh user sshadmin service-type stelnet

2.4 配置aaa

[SWA]aaa
[SWA-aaa]local-user sshadmin password cipher huawei@123
[SWA-aaa]local-user sshadmin privilege level 15
[SWA-aaa]local-user sshadmin service-type ssh 
[SWA-aaa]q

2.5 使用Xshell工具登录

2.6 用户和密码

2.7 登录成功

3. 使用cmd 登录报错提示

Unable to negotiate with 192.168.83.135 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1

3.1 手动指定加密算法，提示密码长度无效

根据提示显示没有匹配到密钥交换算法，所以我们先手动指定下加密算法，显示连接失败

3.2 交换机重新生成密钥，修改为2048即可

[SWA]rsa local-key-pair create 
The key name will be: SWA_Host
% RSA keys defined for SWA_Host already exist.
Confirm to replace them? [y/n]:y
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]:2048

3.3 cmd 使用ssh再次登录

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c 3des-cbc sshadmin@192.168.83.135

3.4 登录成功
