交换机配置:
sftp server enable
ssh user python
ssh user python authentication-type rsa
ssh user python service-type sftp
ssh user python sftp-directory cfcard:/
ssh authorization-type default root
dir
Git Bash生成密钥对:
ssh-keygen -t rsa
Enter
Enter
Enter

cat /c/Users/Administrator/.ssh/id_rsa.pub
交换机添加公钥,并将公钥分配给用户:
rsa peer-public-key rsa01 encoding-type openssh
public-key-code begin
公钥
public-key-code end
peer-public-key end
ssh user python assign rsa-key rsa01

# 下载设备配置文件vrpcfg.cfg,然后上传配置文件test.cfg
# ssh user python assign rsa-key rsa01
# r'C:\Users\Administrator\.ssh\id_rsa'

python代码：
import paramiko
f = open(r'C:\Users\Administrator\.ssh\id_rsa','r')
privaty_key = paramiko.RSAKey.from_private_key(f)

tran = paramiko.Transport(('192.168.56.188',22))
tran.connect(username='python',pkey=privaty_key)
sftp = paramiko.SFTPClient.from_transport(tran)
local_path = r'C:\Users\Administrator\.ssh\test.cfg'
remote_path = '/vrpcfg.cfg'
sftp.get(remote_path,local_path)
sftp.put(local_path,'/test.cfg')
tran.close()
