Is my problems related to Fast and Slow mode (switch in fast and partner in slow mode).
Moreover, during 1 year, I used this configuration without defect. Junos release was 12.3.R9.
I've upgraded 1 week ago to 12.3R12.4.
I'm surprised why all my LACP have timeout today and never during the last year.
Do you think NSB unactivated can be root cause of this issue ?
