Once the accumulated penalty exceeds the suppress threshold value, the interface is moved 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. Once the penalty decays below the reuse threshold, the interface is enabled. The configured parameters should follow: • suppress-threshold should be greater than reuse-threshold • max-suppress-time should be at least 4 times half-life Note: Dampening cannot be applied on an interface that is monitoring traffic for other interfaces.
