新时代网工编程能力变成比敲命令更重要的能力了，大潮流已经无法改变。最近一直在研究python里面的netmiko作为ssh的方法。把第一个脚本共享出来大家研究一下。

方向比较简单，通过python的open方法读取iplist.txt里面的IP地址，这些ip就是所需要下发命令的交换机ip地址。然后读取cmdlist里面需要下发的哪些命令。通过python的netmiko ssh连接到交换机自动下发

import time

from netmiko import *import sysimport osimport getpass

#读取iplist.txt 文档里面的ip地址

iplist = open('iplist.txt','r',encoding = 'ascii')ip_addr = iplist.readlines()iplist.close()

cmdlist = open('cmdlist.txt','r',encoding = 'ascii')

cmd_line = cmdlist.readlines()cmdlist.close()

#遍历ip_addr这个列表里面的ip进行连接

for ip in iter(ip_addr):print(ip)try:S5130 = { 'device_type':'hp_comware','ip':ip,'username':'h3c','password':'h3c',}

net_connect = ConnectHandler(**S5130)    for cmd in iter(cmd_line):        cmd_result = net_connect.send_command(cmd)        print('-----------------------------------------------------------------')        print(cmd)        print(cmd_result)        print('-----------------------------------------------------------------')        print('')    net_connect.disconnect()except (EOFError, NetMikoTimeoutException):    print('Can not connect to Device')except (EOFError, NetMikoAuthenticationException):    print('username/password wrong!')
