Decision making
Decision making related commands include:
● turning route optimization on
● specifying a decision policy that includes policy preferences and the appropriate
application model
● applying the decision policy to the corresponding active measurement group
It is also recommended to insure that when no performance problems are detected, CNA
servers on both ends settle on a different link. To get this behavior, one must specify a priority
under the link command and disable “damped-mode” within the decision policy.
