交换机|python通过telnet（ciscolib和paramiko\netmiko）库批量备份交换机交换机|Python

第一种telnet - ciscolib备份交换机配置文件：
cisco库安装地址：从Github上面下载，进入安装目录：python setup.py install即可

[root@zabbix609 backupsw]# cat telnet_switch3560.py # -*- coding: utf-8 -*- import ciscolib import time import datetimedef main(): PASSWORD="123567567" USERNAME="root" ENABLE_PWD="123456"t = datetime.datetime.now() ot = t.strftime("%Y-%m-%d")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))) continueswitch.enable(ENABLE_PWD) switch.cmd("enable") switch.cmd("c#andphp\n") switch.cmd("copy running ftp:") switch.cmd("10.6.7.15") switch.cmd(ip + "-" + ot + "config.text") switch.disconnect()if __name__ == '__main__': main()

第二种通过SSH加密验证登录备份交换机:paramiko库，基于python 2.7 -->pip install paramiko

[root@zabbix609 backupsw]# ls py-netmiko-bakeup.pyssh_switch2960.pysw2960.txtsw3560.txttelnet_switch3560.py [root@zabbix609 backupsw]# cat ssh_switch2960.py # -*- coding: utf-8 -*- #!/usr/bin/env python import paramiko import time import getpass import datetimeusername = raw_input("Username:") password = getpass.getpass("Password:") t = datetime.datetime.now() ot = t.strftime("%Y-%m-%d")f = open("sw2960.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 "成功登录到Cisco交换机 ", ip print t command = ssh_client.invoke_shell() command.send("enable\n") command.send("c#andphp\n") command.send("copy flash:config.text ftp:\n") command.send("10.6.7.15\n") command.send (ip + "-" + ot + "config.text\n") time.sleep(1) output = command.recv(65535) print output f.close() ssh_client.close

第三种：通过netmiko来管理，这个库非常强大当然也可以管理其它类型交换机

[root@zabbix609 backupsw]# cat py-netmiko-bakeup.py #!/usr/bin/env python # -*- coding: utf-8 -*- # Date: 2019/11/27 # Created by Kelvinfrom netmiko import ConnectHandler import time import osdef Cisco(ip): "思科交换机配置导出函数" cisco_881 = { 'device_type': 'cisco_ios', 'ip': ip, 'username': 'admin', 'password': '1235325', 'port': 22,# optional, defaults to 22 'secret': '134234234',# optional, defaults to '' 'verbose': False,# optional, defaults to False } print u'正在连接交换机：%s\n' % (ip) net_connect = ConnectHandler(**cisco_881) net_connect.enable() commands = [ 'show run', ] timestr = time.strftime('%Y-%m-%d', time.localtime(time.time())) for cmd in commands: filename = u'%s_%s_%s.text' % (ip, cmd.replace(' ', '_'), timestr) save = open(filename, 'w') print u'正在执行命令：' + cmd result = net_connect.send_command(cmd) save.write(result) print u'命令执行完毕，结果保存于当前目录%s中!\n' % filename net_connect.disconnect()if __name__ == '__main__': ips = [ '10.6.110.1', '10.6.110.2', '10.6.110.3', '10.6.110.5', '10.6.110.6', '10.6.110.16', ] for ip in ips: Cisco(ip) # 上传文件至目标服务器 rsync = 'rsync -auv --password-file=/etc/rsyncd.passwd *.text rsync@192.168.1.4::webreport' if os.system(rsync) == 0: print u'文件上传成功!' else: print u'文件上传失败!'
