利用python运维自动化备份交换机配置-paramiko模块

通过ciscolib模块中telnet-23端口批量配置交换机：

下面再讲通过paramiko模块下ssh安全批量配置再下图：

# -*- coding: utf-8 -*-
#!/usr/bin/env python
import ciscolib

def main():
    PASSWORD="12345678"  #//测试环境
    USERNAME="admin"
    ENABLE_PWD="admin123"

    for ip in open('sw3560.txt').readlines():
        ip = ip.strip()

        if USERNAME != "":
            switch = ciscolib.Device(ip, PASSWORD, USERNAME, ENABLE_PWD)
        else:
            switch = ciscolib.Device(ip, PASSWORD, enable_password=ENABLE_PWD)

        try:
            switch.connect()
            print("Logged into %s,Successful" % ip)
        except ciscolib.AuthenticationError as e:
            print("Couldn't connect to %s: %s" % (ip, e.value))
            continue
        except Exception as e:
            print("Couldn't connect to %s: %s" % (ip, str(e)))
            continue

        switch.enable(ENABLE_PWD)
        switch.cmd("enable")
        switch.cmd("c#andphp\n")
        switch.cmd("copy running ftp:")
        switch.cmd("192.168.1.5")
        switch.cmd(ip + "config.text")  #//自动变化配置文件名称
        switch.disconnect()

if __name__ == '__main__':
    main()

通过ssh加密方式配置：

# -*- coding: utf-8 -*-
#!/usr/bin/env python
import paramiko
import time
import getpass

username = raw_input("Username:")
password = getpass.getpass("Password:")

f = open("iplist.txt","r")
for line in f.readlines():
        ip = line.strip()
        ssh_client = paramiko.SSHClient()
        ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh_client.connect(hostname=ip,username=username,password=password)
        print "Sucessfully login to ", ip
        command = ssh_client.invoke_shell()
        command.send("enable\n")
        command.send("c#andphp\n")
        command.send("copy running ftp:\n")
        command.send("192.168.1.5\n")
        command.send (ip + "config.text\n")  #//这里不要设置交换机命令exit退出，否则会出现问题，这里掉过一个坑。
        time.sleep(1)
        output = command.recv(65535)
        print output
f.close()
ssh_client.close
