The value of the object tLagWeightThreshold specifies a threshold for the action specified by the object tLagWeightThresholdAction; the value is a weight, and the unit depends on the value of the object tLagPortWeightSpeed; for example, while the value of tLagPortWeightSpeed is equal to 10, and the value of tLagWeightThreshold is equal to four, the threshold would be reached when a single 40gbps port changes state. When a physical port link state changes and the weight of operational physical ports is less than or equal to the value of tLagWeightThreshold, the action specified by tLagWeightThresholdAction 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 tLagWeightThreshold, 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 tLagWeightThreshold to the total weight of physical ports configured to be in the Link Aggregation Group. A nonzero value of this object overrules the value of the object tLagPortThreshold.
