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
