  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 .
