dampening
Congure dampening on an interface.
Syntax
dampening [[[[half-life] [reuse-threshold]] [suppress-threshold]] [max-
suppress-time]]
Parameters
half-life Enter the number of seconds after which the penalty is decreased. The penalty decreases
half after the half-life period expires. The range is from 1 to 30 seconds. The default is 5
seconds.
reuse-threshold 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.
suppress-threshold 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.
max-suppress-time 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 ap, Dell Networking OS penalizes the interface by assigning a penalty (1024) that decays exponentially
depending on the congured 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
