python批量给交换机下发配置--初级版（下发相同配置）

用paramiko多线程SSH登陆华为交换机处理简单的命令

[root@10-57-22-238 sshsw]# ll
total 12
-rw-r--r-- 1 root root  79 Mar 14 23:53 cmd.txt
-rw-r--r-- 1 root root 274 Mar 14 23:32 conf.py
-rw-r--r-- 1 root root 933 Mar 14 23:51 ssh_sw_cmd.py

cmd.txt用来存放要配置到交换机的命令,内容如下(以下内容为配置NTP)。

sys

conf.py 保存交换机的管理IP,及登陆交换机的用户名密码

#-*- coding: utf-8 -*-
#!/usr/bin/python
#要执行操作的交换机管理

#交换机SSH用户名密码    
username = "wsf535"  #用户名
passwd = "****"    #密码
threads = [10]   #多线程

data.csv储存设备名与ip

torname,ip
