With each flap, Dell Networking OS penalizes the interface by assigning a penalty (1024) that decays exponentially depending on the configured half-life. After the accumulated penalty exceeds the suppress threshold value, the interface moves to the Error-Disabled state. This interface state is deemed as “down” by all static/ dynamic Layer 2 and Layer 3 protocols. The penalty is exponentially decayed based on the half-life timer. After the penalty decays below the reuse threshold, the interface enables. The configured parameters are as follows:

•suppress-threshold should be greater than reuse-threshold

•max-suppress-time should be at least 4 times half-life

NOTE: You cannot apply dampening on an interface that is monitoring traffic for other interfaces.
