Configuring a specific link for a decision policy
From Policy Configuration mode, you can access Link Policy Configuration mode (confide-engine-policy-link), from which you can set any link parameter. For more information on how to access Link Policy Configuration mode, see Link Policy Configuration command mode.
Important: When you access Link Policy Configuration mode, the commands that you enter apply to the designated link only for those subnets associated with the current decision policy.
