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.

module engine damped-mode disable link provider_1

winner-set-priority prefer end

route-assert-mode enable
