ArubaOS-CX: Shouldn't flow-control rx enablement on physical interfaces be an undisruptive action?

Hi all,

 

I'm massively enabling flow-control rx on all of our sixteen VSX LAGs member interfaces (for a grand total of 54 physical interfaces: 27 on each VSX node).

 

Question: why enabling flow-control rx on a physical interface should cause it to go through down/up states instead of being a totally undisruptive/transparent configuration change?

 

Is the observed behaviour normal or am I expecting a little bit too much by such setting change?

 

Before starting doing it massively I did a test on just one VSX LAG involving just two pairs of interfaces (I did sequentially on them).

 

The flow-control rx was enabled on VSX-2 first, first 1/1/2 then 1/1/1:
