The value of the object tLagHashWeightThreshold specifies a threshold for the action specified by the object tLagHashWeightThresholdAction; The value of tLagHashWeightThreshold is compared to the sum of the values of tLagPortHashWeight of all active physical ports in the LAG. When a physical port link state changes and the hash weight of operational physical ports is less than or equal to the value of tLagHashWeightThreshold, the action specified by tLagHashWeightThresholdAction is invoked: either the LAG is set operationally down, or the protocols operating on the LAG interface are adjusted. When the weight of the operational physical ports becomes greater than the value specified by tLagHashWeightThreshold, the action is revoked: either the LAG is set operationally up, or the protocols operating on the LAG interface are adjusted. The value zero means that the action is never invoked. To invoke dynamicCost at every physical port state change, set the value of tLagHashWeightThreshold to the total weight of physical ports configured to be in the Link Aggregation Group.
