This read-write Unsigned32 object (0-65535) associates a preferred route with a connection, defined in the cwaPrefRouteConfTable, where a value of 0 means no preferred route is associated and automatically causes vismChanDirectRoute to be set to FALSE by the agent. This lets an admin bias PXM's routing decisions toward a specific preconfigured route for a connection rather than relying on default path selection. An engineer wanting a critical connection to prefer a specific known-good network path would set this object to that route's ID from the preferred route configuration table.
