python------备份设备配置脚本（二）

字典型

sw1上

[SW1]user-interface vty 0 4

[SW1-ui-vty0-4]screen-length 0

sw2上

[SW2]user-interface vty 0 4

[SW2-ui-vty0-4]screen-length 0

SW1_info = {"ip_addr":"192.168.100.1",
           "username":"dyx",
           "passwd":"Huawei@123",
           "device_name":"SW1",
           "device_type":"交换机"}

SW2_info = {"ip_addr":"192.168.100.2",
           "username":"dyx",
           "passwd":"Huawei@123",
           "device_name":"SW2",
           "device_type":"交换机"}

database = [SW1_info, SW2_info]

#display current-configuration 查看当前的配置
#display saved configueation
#display current-configuration | include ip route 命令筛选

import paramiko
import time
from datetime import datetime
from device import *
for i in range(len(database)):

    #创建一个SSH客户端
    ssh_client = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh_client.connect(hostname=database[i]["ip_addr"],username=database[i]["username"],password=database[i]["passwd"])

    command = ssh_client.invoke_shell()
        #给设备发送“查看配置”命令
    command.send("system-viewn"
             "user-interface vty 0 4 n"
             "screen-length 0 n".encode())
    command.send("dis cun".encode())
    time.sleep(3)
    recv = command.recv(65535).decode()
    #print(recv)
    #recv 就是设备给我们返回的结果，但是，如果直接将这个结果写入文件
    #文件呈现的效果是，一行结束，会多一个回车
    #处理方法：recv这个大文件，通过.splitlines()，将它的每一行进行切割，组成一个列表
    #遍历列表，即大文件的每一行，将每一行再写入配置文件即可
    resut = recv.splitlines()
    #print(resut)
    back_time = str(datetime.now())
    now_time = back_time[0:-7].replace(":","：")
    with open(f"{database[i]['device_name']}-{now_time}.txt",'w')as file_backup:
        for item in resut:
            print(item)
    #将回显内容保存到本地
            file_backup.write(item+"n")
ssh_client.close()

运行后：

查看带时间

在X-shell上
