Note The up->down counter records the number of times the plane has flapped between UP and
DOWN. Similarly, up->mcast_Down counter records the number of plane transitions between
MCAST_DOWN and UP].
Before starting the downgrade process, take a snapshot of the traffic flowing through the router and use
it as a benchmark to compare against traffic flow during the downgrade and/or after completing the
downgrade. Since it is a hitless downgrade, there should be zero impact to the traffic flow during the
downgrade and/or after completing the downgrade.
