1.过程思路

1. 备份配置前，先保存交换机running config到starup config
2. 交换机通过tftp备份配置文件
3. 批量备份交换机配置（通过excel文件保存交换机IP）

2.python代码

import xlrd
import paramiko
import time

def ssh_SW(name,ip):
    now = time.strftime("%Y%m%d", time.localtime(time.time()))
    trans = paramiko.Transport((ip, 22))
    trans.connect(username='admin', password='passwd')
    ssh = paramiko.SSHClient()
    ssh._transport = trans
    stdin, stdout, stderr = ssh.exec_command('save')
    print(stdout.read().decode())
    stdin, stdout, stderr = ssh.exec_command('tftp 10.x.x.100 put startup.cfg ' + name + '-' + now + '.cfg')
    print(stdout.read().decode())
    trans.close()

def main():
    workbook = xlrd.open_workbook('./sw.xlsx')
    sheet = workbook.sheet_by_name('Sheet1')
    count = sheet.nrows
    for i in range(count-1):
        i = i + 1
        rows = sheet.row_values(i)
        name = rows[0]
        ip = rows[1]
        ssh_SW(name,ip)

if __name__=="__main__":
    main()

3.脚本很简单，还有待完善
