Redfish permanent re-detection of physical interfaces with new id?

[47k]

On all the Redfish Server I have a permanent re-detection of my interfaces with an id after the physical port which increased by 1:

[47k]

Same with Storage controller:

That cannot happen without a firmware change or something like this.
These IDs are reported by the controller itself.
You are sure that nothing was done on these systems?

Yes I'm sure - on the listed systems I changed the MTU in Windows to activate Jumbo Frames. And about the Storage Controller - nothing changed. But I saw this behavior on all my iLO4 and iLO5 Systems from time to time (once or twice per week - or every two weeks)

I don't know why these ports or storage controller change the used id.
To say some more i need two agent outputs from one of these machines.
Before and after such a change.
