This object enables/disables automatic rebalancing of the
server to external interface assignments such that number of
server interface assigned to the external interfaces are
evenly distributed as much as possible. Redistribution of the
server interfaces are done with the constraints of VSANs
assigned to the interfaces and traffic maps specifying which
external interface a server interface can take.
When this feature is enabled or when an external interface comes
up, then the switch reevaluates the current distribution
and determines if a rebalancing is required.
During the move of server interface from one external
interface to another, there is a temporary traffic disruption
for that server interface.
