Sujit I know that this is LACP debug . I am trying to understand the specific conditions that this LACP disconnect sequence is occurring. It’s a odd thing, it’s happening during times of relatively low was tcp traffic . The router and is not highly loaded and I can’t find a reason why this is occurring . --- Mark Saad | nonesuch@longcount.org On Jul 12, 2020, at 6:22 AM, Sujit K M <kmsujit@gmail.com> wrote: > > > > >> On Sat, Jul 11, 2020, 10:03 PM Mark Saad <nonesuch@longcount.org> wrote: >> All >> This is a repost from net .
