Automatic Telnet to cisco switches

I have many switches that we backup every night. I need to create a job that will automatically backup the running config.

I am currently using this, but how can I use a list of server ip addresses instead of having to repeat the code.

Dim WshShell

set WshShell=CreateObject("WScript.Shell")

WshShell.run "cmd.exe"

WScript.Sleep 1000

'Send commands to the window as needed - IP and commands need to be customized

'Step 1 - Telnet to remote IP'

WshShell.SendKeys "telnet 10.1.130.91 23"
WshShell.SendKeys ("{Enter}")

Solution

  • Here you go. Just create a file named CiscoIPs.txt with all your IP address with a carriage return after each one. Avoid spaces at the end of the records.

    10.2.2.23
10.4.5.23
10.5.7.23

    The IP list should be in the same folder as the VBScript, but you can certainly change this by editing "strIPFile = "CiscoIPs.txt" at the top of the script. Let me know if you have any issues.

    Option Explicit
Dim WshShell, strIPFile, objFSO, objFile, IPAddress

strIPFile = "CiscoIPs.txt"

On Error Resume Next

set WshShell = CreateObject("WScript.Shell")
Set objFSO = CreateObject("Scripting.FileSystemObject")

Const ForReading =   1
Const ForWriting =   2
Const ForAppending = 8
Const ReadOnly =     1

Set objFile = objFSO.OpenTextFile(strIPFile, ForReading)

Do Until objFile.AtEndOfStream
  IPAddress = objFile.ReadLine
  'WScript.Echo IPAddress
  WshShell.run "cmd.exe"

  WScript.Sleep 1000

  'Send commands to the window as needed - IP and commands need to be customized

  'Step 1 - Telnet to remote IP'

  WshShell.SendKeys "telnet " & IPAddress & " 23"

  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 1000

  'Step 2 - Issue Commands with pauses'

  WshShell.SendKeys ("password")

  WScript.Sleep 1000

  WshShell.SendKeys ("{Enter}")

  WScript.Sleep 500
  WshShell.SendKeys ("Enable")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("password")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("show running-config")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("copy run tftp://" & IPAddress & ".xls")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("10.1.211.53")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500

  WshShell.SendKeys ("file1.xls")
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 2000

  'Step 3 - Exit Command Window

  WshShell.SendKeys "exit"
  WshShell.SendKeys ("{Enter}")
  WScript.Sleep 500
  WshShell.SendKeys "exit"
  WshShell.SendKeys ("{Enter}")
