Batch automatic backup switch configuration using expect

Improve productivity by using the expect tool with the shell to automate the ability to back up switch configurations.

Software: expect-5.44.1.15-4.el6.i686

Purpose: By reading the contents of the file, automatically log in to the network device, complete the corresponding command, and finally read the configuration information, save as a file.

Here's the code:

1, main.sh #通过shell脚本来实现对文件内容的读取, and call expect script to complete the device configuration read and save.

#!/bin/bash

For line in ' Cat/tmp/hosts.txt ' #逐行读取hosts文件内容

Do

Server= ' echo $line |awk-f | ' {print '} '

Login= ' echo $line |awk-f | ' {print $} '

Passwd= ' echo $line |awk-f | ' {print $} '

Enpasswd= ' echo $line |awk-f | ' {Print $4} '

./get_switch_conf.exp $server $login $passwd $enpasswd

Sleep 3

Done

2, Get_switch_conf.exp #通过expect脚本来完成自动登录设备, read information, save information.

#!/usr/bin/expect-f

if {$ARGC! = 4} {

Send_user "Usage: $argv 0 <server> <login> <password> <enpassword>\n"

Exit

}

Set timeout 1

Set term ANSI

Set SERVER [lindex $argv 0]

Set LOGIN [lindex $argv 1]

Set PASSWD [lindex $argv 2]

Set ENPASSWD [lindex $argv 3]
