    Hi,

    I have a pair of EX9208 forming ESI-LAGs towards FW and access switches. When rebooting one chassis (both RE) I noticed is that the LACP-AE (ae402) between the two chassis goes down instantly, while the physical members towards the other chassis remain up until the chassis has completed its reload and starts re-initializing its linecards. This leads to problems towards devices which make descisions based on link up/down status and dont care about LACP (maybe a bug there but whatever).

    My questions is if there is a way to get physical ifs down instantly after reloading the chassis? 

    Thank you.
