Usage
Information
With each flap, FTOS 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.
Example
FTOS(conf-if-te-3/2)#dampening 20 800 4500 120
