Usage Information With each ap, Dell EMC Networking OS penalizes the interface by assigning a penalty (1024) that decays
exponentially depending on the congured 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 congured 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 trac for other interfaces.
Example
DellEMC(conf-if-te-1/10)# dampening 20 800 4500 120
DellEMC(conf-if-te-1/10)#
