Usage
Information
With each flap, Dell EMC 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.
Example
DellEMC(conf-if-te-1/10/1)# dampening 20 800 4500 120
DellEMC(conf-if-te-1/10/1)#
