Unable to modify link speed if higher than the interface speed

[Bartosz Woronicz]

Intel card reporting higher link speed thank Interface speed.
But it would be ok, issue with the speed reporting, maybe firmware update would help, but
I cannot change the speed in the GUI interface.
Once it gathered these value, the save button is greyed out (see the screenshots)

Work around for it is to use CLI

This is how it looks

Hi, which version of MAAS are you currently using? In more recent versions this field has been changed to produce a warning rather than preventing the form from being submitted.

[Jerzy Husakowski (jhusakowski)]

Is this reproducible on MAAS 3.1 or 3.2 beta?

[Bartosz Woronicz (mastier1)]

I don't have that hardware anymore to check out.
You would need to simulate it somewhat.

The behaviour has been changed in the UI in a previous version of MAAS. If this issue occurs again we will reopen this ticket.
