ICX 7450 firmware downgrade process?

[rahul_chakravar]

Where can I find some documentation on how to downgrade the switch firmware from 09.0.10c to the recommended 08.0.95j release?

I have issues with 802.1x implementation so I'd like to downgrade my firmware in the Dev environment.

Hello Rahul,

Greetings!

The downgrade process is similar to the upgrade process.

Please find the steps below for downgrading the switch:
How to download the Software? Go to: https://support.ruckuswireless.com//

1. Click on "download"

2. Choose the product (Ruckus ICX7xx Campus Switches)

3. Download the required version

Steps for downgrading via TFTP

1. Charge the software on a TFTP server, the TFTP server should have ping connectivity with the switch.

2. Get console access and test the ping connectivity with the command brocade# ping x.x.x.x. Note: if you have a stack get console access from the active controller.

3. Issue the Show flash command to confirm e version.

4. Upgrade the image software version on primary/secondary partition

Switch# copy tftp flash x.x.x.x <filename> primary/secondary ("show flash" to confirm)

NOTE: On a stack environment implement the upgrade from the active controller and it will copied to the member automatically.

6. Boot from primary/secondary partition

Switch# boot system flash primary/secondary.

7. Upgrading to 8095h UFI desired version.

8. Once the switch is up, please verify if it has upgraded successfully via "show version" command

Note : Please take a config backup, prior to the downgrade(few of the features may not support in the downgraded version).

Also refer below links regarding limitations and consideration:

Hi Rahul,

General Considerations for Upgrade to or Downgrade from FastIron 09.0.10a or Later

Note: Before you begin an upgrade/downgrade, read the release notes for the target release carefully to familiarize yourself with any behavior and CLI changes.

RUCKUS ICX FastIron 09.0.10c Release Notes

https://support.ruckuswireless.com/documents/4196-ruckus-icx-fastiron-09-0-10c-ga-release-notes

Before upgrading/downgrading to FastIron 09.0.10a or a later release, RUCKUS strongly recommends the following steps:

Make a backup copy of the ICX startup configuration (the startup-config file). This copy will be used if a upgrade/downgrade to a previous release is necessary. If you have made changes to the running configuration, you may also want to save a copy of the running-config file.
The following example saves a copy of a FastIron 08.0.95 startup configuration and a running configuration and stores them on the TFTP server, identified by its IP address.

ICX# copy startup-config tftp 10.176.198.42 old-8095-cfg
ICX# Upload startup-config to TFTP server done.
ICX# copy running-config tftp 10.176.198.42 old-8095-run-cfg
ICX# Upload running-config to TFTP server done.

Reference: https://docs.commscope.com/bundle/fastiron-09010-upgradeguide/page/GUID-850E8EA8-9099-49D0-8427-7068...

If the switches are in stack, there is a possibility of stack split.

Because the stack configuration commands vary from 8095 to 9010.

As Nidhi mentioned, firmware downgrade procedure is similar to firmware upgrade.You can follow the same.

Thanks,
Vivek
