Paramiko SSH登入華為裝置
ALT + PrtSc 截圖當前視窗
PrtSc 截圖全屏
1、新建Topo如圖：
交換機選擇CE12800，加個Cloud，通過Copper連線。
2、配置Cloud埠，先新增UDP埠GE1，再新增VirtualBox Host-Only Network橋接埠。
對映埠配置如Port Map Setting：入埠Local Port Num1，出埠Remote Port Num2，勾選雙向通道
3、交換機配置：
<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
PING 192.168.56.1: 56 data bytes, press CTRL_C to break

配置後發現ping不通閘道器地址，檢視故障原因是埠未啟動。
啟動埠：
[~CE1]int g1/0/0
[~CE1-GE1/0/0]un shutdown
[*CE1-GE1/0/0]com
[~CE1-GE1/0/0]q
[~CE1]ping 192.168.56.1

交換機配置思路：
1、 配置Stelnet：配置管理IP，使能Stelnet功能，配置使用者介面
2、 配置使用者：建立本地使用者和SSH使用者，配置服務型別和認證方式
3、 配置公鑰：新增客戶端生成的公鑰並分配給使用者
3.1 建立金鑰對：本地生成公鑰和私鑰
3.2 編寫python程式碼
3.3 結果驗證
具體配置：
使能交換機STelnet功能，配置VTY使用者介面。
stelnet server enable
user-interface vty 0 4
authentication-mode aaa
protocol inbound ssh
user privilege level 3
q
建立本地使用者python ,將使用者加入管理員組，並配置使用者服務方式
aaa
local-user python password irreversible-cipher Huawei@123
local-user python user-group manage-ug
local-user python service-type ssh
建立SSH使用者，配置認證方式和服務方式
ssh user python
ssh user python authentication-type rsa
ssh user python service-type stelnet
windows系統下的cmd命令列是不能直接使用ssh命令的，
所以使用Git Bash 建立RSA金鑰對，並將公鑰拷貝到交換機
ssh-keygen -t rsa
d:\python/key_file_name
password
password
(金鑰儲存目錄d:\python要存在，否則會報錯;金鑰檔名稱自己取；金鑰目錄，密碼和確認密碼時都可以為空，直接按三次Enter也可以)
目錄d:\python下會生成一個私鑰，一個公鑰，以.pub結尾的是公鑰。
顯示公鑰
cat /d/python/id_rsa_pwd.pub
複製公鑰
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCwWXfSl0VDxkncszZ4ZDl3bZcTeIscegyTXXlmXwD69DjVhSW+xsiLsJcrl6y9lUDO4LHHHeCXOaUXWhvs7GZI5AvPLAgWnSmt6vJXrhiDv86Qcj1F37GeEdmzXWnwSsoWr9ic73O/Hy+1KAYR7Cp6D4oRessbfmXLZRU/IgSrhWgat53JyWcF2LtTd1M+A4fODkNczf51OQVkAc12cDtWSryMVhT83k3tF3Vf9upeL2EGDaBLsuSPrr4Ss3Fu7wpVOW18gEDxtHveyxbOrgArG4qBdxdIe9dLLkZozEcm4bxQzZpkqKBuy71HChu6BbnS0wegg7JkjKiRxsRS1o4l administrator@geng
在交換機上新增公鑰，並將公鑰分配給使用者
