1、新建Topo如图：

交换机选择CE12800，加个Cloud，通过Copper连线。

2、配置Cloud端口，先添加UDP端口GE1，再添加VirtualBox Host-Only Network桥接端口。

映射端口配置如Port Map Setting：入端口Local Port Num1，出端口Remote Port Num2，勾选双向通道

3、交换机配置：

<HUAWEI>sys
Enter system view, return user view with return command.
[~HUAWEI]sysn CE1
[*HUAWEI]int vlani 1
[*HUAWEI-Vlanif1]ip add 192.168.56.188 24
[*HUAWEI-Vlanif1]q
[*HUAWEI]com
[~CE1]ping 192.168.56.1

--- 192.168.56.1 ping statistics ---

配置后发现ping不通网关地址，查看故障原因是端口未启动。

启动端口：

[~CE1]int g1/0/0
[~CE1-GE1/0/0]un shutdown
[*CE1-GE1/0/0]com
[~CE1-GE1/0/0]q

交换机配置思路：

1、配置Stelnet：配置管理IP，使能Stelnet功能，配置用户界面

2、配置用户：创建本地用户和SSH用户，配置服务类型和认证方式

3、配置公钥：添加客户端生成的公钥并分配给用户

3.1 创建密钥对：本地生成公钥和私钥

3.2 编写python代码

3.3 结果验证

具体配置：

使能交换机STelnet功能，配置VTY用户界面。

stelnet server enable

user-interface vty 0 4

authentication-mode aaa

protocol inbound ssh

user privilege level 3

创建本地用户python ,将用户加入管理员组，并配置用户服务方式

aaa

local-user python password irreversible-cipher Huawei@123

local-user python user-group manage-ug

local-user python service-type ssh

创建SSH用户，配置认证方式和服务方式

ssh user python

ssh user python authentication-type rsa

ssh user python service-type stelnet

windows系统下的cmd命令行是不能直接使用ssh命令的，

所以使用Git Bash 创建RSA密钥对，并将公钥拷贝到交换机

ssh-keygen -t rsa

d:\python/key_file_name

password

(密钥保存目录d:\python要存在，否则会报错;密钥文件名称自己取；密钥目录，密码和确认密码时都可以为空，直接按三次Enter也可以)

目录d:\python下会生成一个私钥，一个公钥，以.pub结尾的是公钥。

显示公钥

cat /d/python/id_rsa_pwd.pub

复制公钥

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCwWXfSl0VDxkncszZ4ZDl3bZcTeIscegyTXXlmXwD69DjVhSW+xsiLsJcrl6y9lUDO4LHHHeCXOaUXWhvs7GZI5AvPLAgWnSmt6vJXrhiDv86Qcj1F37GeEdmzXWnwSsoWr9ic73O/Hy+1KAYR7Cp6D4oRessbfmXLZRU/IgSrhWgat53JyWcF2LtTd1M+A4fODkNczf51OQVkAc12cDtWSryMVhT83k3tF3Vf9upeL2EGDaBLsuSPrr4Ss3Fu7wpVOW18gEDxtHveyxbOrgArG4qBdxdIe9dLLkZozEcm4bxQzZpkqKBuy71HChu6BbnS0wegg7JkjKiRxsRS1o4l administrator@geng

在交换机上添加公钥，并将公钥分配给用户

rsa peer-public-key rsa01 encoding-type openssh

public-key-code begin

public-key-code end

peer-public-key end

ssh user python assign rsa-key rsa01
