Switch configuration backup using PowerShell

In this article, I will briefly explain how to backup running configuration of your Dell switches to a TFTP server location using PowerShell.

Prerequisites

• A TFTP server should be configured and running

Workflow

1. Get a list of IP address of switches that needs to be backed up
   
   list = Get-Content .\switch_list.txt
2. Collect credentials to SSH into the switch
   
   $creds = Get-Credential
3. Create a new SSH session to the first switch in the list
   
   $sw_ssh = New-SshSession -ComputerName 192.168.10.2 -Credential $creds -Force -ConnectionTimeout 300
4. Invoke the command to backup running config to TFTP server over the SSH session
   
   $filename =(Get-Date).tostring("dd-MM-yyyy-hh-mm-ss")
   $cmd_backup = "copy running-config tftp://192.168.11.33/sw01/$filename.txt"
   Invoke-sshcommand -Command $cmd_backup -SSHSession $sw_ssh
5. Repeat step 3 and 4 for all the switches in the list

Note

You can schedule this PS script using a task scheduler so that the running configuration of switches can be backed up automatically on a daily basis or as per requirements.

Hope this was useful. Cheers!
