reuse-threshold suppressthreshold max-suppresstime period expires. The range is from 1 to 30 seconds. The default is 5 seconds. Enter a number as the reuse threshold, the penalty value below which the interface state is changed to "up". The range is from 1 to 20000. The default is 750. Enter a number as the suppress threshold, the penalty value above which the interface state is changed to "error disabled". The range is from 1 to 20000. The default is 2500. Enter the maximum number for which a route can be suppressed. The default is four times the half-life value. The range is from 1 to 86400. The default is 20 seconds. Defaults Disabled.

Usage Information With each flap, the system 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 ErrorDisabled 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. 866 Interfaces
