How to upgrade N3K-C3548P-10GX

[Michal Rzepecki]

We got few N3K-C3548P-10GX switches running 6.0(2)A8(7a). I've tried to upgrade one of these to 7.0(3)I2(2)  (this is the only available software for this platform) but switch didn't allow to do this upgrade. Release notes says that at least 6.0(2)U6(3a) version is needed to upgrade to 7.0(3)I2(1).

So I undestand that I need to upgrade from 6.0(2)A8(7a) to 6.0(2)U6(3a or higher) and than to 7.0(3)I2(2)?

How can I upgrade from 6.0(2)A8(7a) to 6.0(2)U6(3a or higher)? I can't find this upgrade\downgrade path in any release notes.

I would upgrade to 6.0(2)A8(7) then to 7.0(3)I2(2). I just did this last year.

I've tried to upgrade 6.0(2)A8(7a) to 7.0(3)I2(2) last week and switch notified that this is not possible. What platform you've upgraded? In my case it is 3500X.

[Rick1776]

The customer I was helping has a 3548(Non-X) switch. It runs the same NX-OS code.

It's super weird, if you go to this page. It has all the software for the 3500(non-x) switches which has all the releases.
https://software.cisco.com/download/release.html?mdfid=284365099&flowid=36882&softwareid=282088129&release=6.0(2)A8(4a)&relind=AVAILABLE&rellifecycle=&reltype=latest

If you go to the 3500 (X Version) it only has NX-OS version 7.0(3)I7(2)

Can you paste a copy of the "show inventory", "show module", and "Show Ver" command output in your response.

Sh ver has been taken before upgrade to 6.0(2)A8(7)

Look like you have to do an "install all" because it has to upgrade the BIOS version as well.
