Firmware update on Cisco SF300 using CLI

[Ivan Sergeev]

Hi all!

How I can update the firmware on Cisco SF300 using CLI?

I have download the new firmware Sx300_FW_Boot_1.4.0.88 from the Cisco website. Inside the archive I found two files sx300_boot-13506.rfb and sx300_fw-14088.ros. If I understand correctly, sx300_fw-14088.ros is the firmware?

Through the command  #copy image tftp://mytftp/image i have stored the current firmware in my TFTP

And now I must use the command #copy tftp://mytftp/sx300_fw-14088.ros image, for  update, right?

This is enough to update the firmware? How can I use another file sx300_boot-13506.rfb?

Hi Ivan,

Please find below the full set of commands you need during upgrade. Please note that switch stores 2 images and new firmware would go to non active image thus you have to set active image.

#copy tftp://mytftp/sx300_fw-14088.ros image

#show bootvar

       image-x 1.4.0.88

       image-y a.b.c.d.

#boot system image-x

for the boot code however:

#copy tftp://mytftp/sx300_fw-13506.rfb boot

After all those commands you may reboot the switch and verify boot code and firmware:

#show version

I hope this helps,

Aleksandra

Thank`s  for manual, but I have some problems. When I try copy firmware I recive error: Copy: Illegal software format. I found a hint here: https://supportforums.cisco.com/discussion/12286911/sg300-firmware-upgrade-copy-illegal-software-format, and I try upgrade the boot loader before update the firmware. However, the error remained.

Hi Ivan,

Please note that before going to 1.4 firmware you should have 1.3.5 boot code and firmware and switch require reboot. The following link should be helpful:

Hi, Aleksandra,

really, the problem was in the missing firmware 1.3.5, your link was very useful!

Many thanks for the good advice!

Best regards,

Ivan

Hi Aleksandra,

I am having the same issue we purchased 12 of the SF300-24 switches that have 1.3.0.62 however immediate upgrade is not working on the switch using the GUI - Do I have to upgrade the device image to 1.3.5 or 1.3.7 before I can go with 1.4.0x release?

 I have the current image downloaded and want to go to newer version sx300_fw-14088.ros which I am getting illegal software image errors, where do I get the 1.3.5 or 1.3.7 images I cannot find them only the latest 1.4.0.88 is all Cisco is showing.

2      image-2    1.3.0.62    02-May-2013  14:55:01   Not active*
 

and cannot go to newest version

Hi Gary,

Yes this is because the boot code was not upgraded to the current 1.3.5.06 version.

Please check below guide which should help you to perform tftp boot code upgrade:

Hi Gary,

There are some things you need to pay attention when testing. If it is not too late you can always post more information on what you are trying to achieve.

Note: since it is going to be different subject I would recommend you to create new post.

Regards,

Aleksandra
