WN Blog 015 – Cisco Catalyst 9800 – Software Upgrade

Upgrading Cisco Catalyst 9800 software is easy and sleek.

You could use all standards protocols to put a new image on the controller: FTP, TFTP, SFTP or HTTPS.

Here are the steps:

  • Download new .bin image from Cisco; I went for the newest TAC recommended image.
  • On the WLC, go to Administration > Software Upgrade or simply start writing ‘upgrade’ in the search bar. Select Transport Type (I used HTTPS), bootflash File System and select newly downloaded image with .bin extension. Click ‘Download & Install‘ and confirm that you really, truly and purposefully want to do it!
  • Wait for the file to finish downloading to the WLC and hit ‘Save Configuration & Reload‘ once Status is all green.
  • Lastly, train your Jedi skills. Be patient.

Installation and reload is extremely fast and takes just a minute or two (at least for the CL version).

Enjoy!
