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 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.

Dell(conf-if-te-2/2)#dampening 20 800 4500 120
