用python的paramiko文本txt批量登陆设备配置

当我们的登陆设备地址不连续的情况下，或者不同网段，我们就不能简单的使用for循环来登陆设备了。
我们要额外建立一个文本文件，把需要登陆的交换机的管理IP地址全部写进去，然后用for循环配合open()函数来读取该文档中的管理地址

拓扑

交换机配置

以LSW2为例：

interface Vlanif1
 ip address 192.168.56.2 255.255.255.0
#
aaa
 local-user admin password cipher Huawei@123   //创建python用户，密码为123
 local-user admin privilege level 15
 local-user admin service-type ssh
#
user-interface vty 0 4
 authentication-mode aaa
 protocol inbound ssh
#
stelnet server enable
ssh user admin authentication-type all
ssh user admin service-type all
ssh client first-time enable

目的

在多台设备上关闭stp

代码

需要在本地创建一个TXT文件，把需要登陆配置的设备管理IP都放进去
如果该文件与py文件在同一个文件夹会方便很多

ip_list：
192.168.56.2
192.168.56.10
192.168.56.52

import paramiko
import time

username = input('Username: ')
password = input('Password: ')

f = open("ip_list.txt", "r")
for line in f.readlines():   #迭代文件的每一行数据
    ip = line.strip()   #去除字符串两端的空白符
    ssh_client = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh_client.connect(hostname=ip, username=username, password=password, look_for_keys=False)
    print("Successfully connect to ", ip)
    command = ssh_client.invoke_shell()
    command.send(b"screen-length 0 temporary\n")
    command.send(b"sys\n")
    command.send(b"undo stp enable\n")
    command.send(b"Y\n")
    command.send(b"q\n")
    command.send(b"save\n")
    command.send(b"Y\n")
    time.sleep(1)
    output = command.recv(65535)
    print(output.decode("ascii"))

f.close()
ssh_client.close()

结果
