Solucionado: Re: Doubt with Cisco Catalyst 9400 upgrade

Julian Ortiz · ‎06-21-2024

Hi community,

I have a doubt about upgrading a switch Cisco Catalyst 9400. Beside to the software image upgrade, the Release Notes say “ROMMON and CPLD version upgrade process must be completed after upgrading the software image.”. Is this true? If so, where can I find the ROMMON and CPLD images/files? I searched in the Software Download page and there are only software images.

This is the link with the information:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9400/software/release/17-9/release_notes/ol-17-9-9400/upgrading_the_switch_software.html#task_b1z_hwr_43b

It seems CPLD must be upgrade:

CPLD version upgrade process must be completed after upgrading the software image.

For the ROMMON, I am a little confused:

You can upgrade the ROMMON before, or, after upgrading the software version. If a new ROMMON version is available for the software version you are upgrading to, proceed as follows:

Upgrading the ROMMON in the primary SPI flash device
This ROMMON is upgraded automatically. When you upgrade from an existing release on your switch to a later or newer release for the first time, and there is a new ROMMON version in the new release, the system automatically upgrades the ROMMON in the primary SPI flash device, based on the hardware version of the switch.
Upgrading the ROMMON in the golden SPI flash device
You must manually upgrade this ROMMON. Enter the upgrade rom-monitor capsule golden switch command in privileged EXEC mode.

Maybe someone with experience with this type of upgrades can shed some light here.

Thanks in advance,

Julián

Direct downgrade is supported.

Hi everyone,

Any idea?

The microcode upgrade is done automatically.

The FPGA &/or golden capsule upgrade has to be done manually.

Julian Ortiz · ‎06-24-2024

Hi Leo,

With microcode do you mean ROMMON or CPLD?

Regads,

Julián

Georg Pauwen · ‎06-24-2024

Hello,

as I understand it, the ROMMON (or microcode/firmware as mentioned by @Leo Laohoo ) is upgraded automatically when the software is updated, and CLPD has to be done manually, using the 'upgrade hw-programmable cpld filename ' exec command. Auto-upgrade of the CLPD is not supported (see the link below):

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9400/software/release/17-9/release_notes/ol-17-9-9400/upgrading_the_switch_software.html#id_116258

Julian Ortiz · ‎06-24-2024

Hi Georg,

Then, in the command “upgrade hw-programmable cpld filename”, filename is the name of a CPLD file. Where can I find this file?

I searched in the Software Download page and there are only software images (IOS), for example the following for IOS-XE 17.9.5:

There is no CPLD files. Or if the image file is for instance "cat9k_iosxe.17.09.05.SPA.bin", do I have to run "upgrade hw-programmable cpld flash:cat9k_iosxe.17.09.05.SPA.bin"?

------------------EDITED-----------------

More things I found, it seems the CPLD upgrade is not necessary based on these:

shambhu.kumar · ‎06-25-2024

Hi Julian,

for safer side upgrade 17.3.x to 17.6.x then upgrade 17.9.x

using "install add file flash:cat9k_iosxe.x.x.x.SPA.bin activate commit" ROMMON will be upgraded automatically , no need to upgrade CPLD or FPGA,

Julian Ortiz · ‎06-25-2024

Hi Shambhu,

An intermediate jump? The release notes say nothing about jumping to an intermediate image. Where did you find that information?

Regards,

Julián

shambhu.kumar · ‎06-26-2024

Hello Julian,

I have four Catalyst 9400 Series 7 Slot Chassis, I have upgraded from 17.03.05 to 17.06.05 in first two chassis.

in second two 9400 Series 7 Slot Chassis I have upgraded from 17.03.05 to 17.06.05 and then 17.08.01.

below captures are for your reference, intermediate jumping from one version to another is not well documented.

Hello Julian,

I have four Catalyst 9400 Series 7 Slot Chassis, In two chassis I have upgraded 17.06.05 from 17.03.05

and another two chassis it has been upgraded from 17.03.05 to 17.06.05 and later 17.08.01. You can directly upgrade 17.03.X to 17.9.X. No neded to care about ROMMON, CPLD and FPGA. It will upgrade automatically.

Thanks

Julian Ortiz · ‎06-26-2024

Thanks for the information.

As a test, I have successfully upgraded the firmware of a C9500-48Y4C, from 17.3.5, to 17.12.3. (See attached file.)

NOTE: A 9500 is "different" to a 9400 or 9600 Supervisor card, however, they share a lot of common architecture and, I will assume, behaviour.

(The start of the file will show that the C9500-48Y4C boots up in ROMMON version 17.3.1r. After the reboot, and before 17.12.3 is loaded, the switch conducts an "bootloader upgrade" and then rebooting to ROMMON version 17.8.1r.)

This is further proof that direct upgrade, from 17.3.X, to 17.12.3 is supported and no need to go to an intermediate version as a prerequisite.

Thank you very much for your interest!
