Commands
show config – displays the configuration of the selected interface.
dampening
Configure dampening on an interface.
Syntax
dampening [[[[half-life] [reuse-threshold]] [suppress-
threshold]] [max-suppress-time]]
To disable dampening, use the no dampening [[[[half-life] [reuse-
threshold]] [suppress-threshold]] [max-suppress-time]] command.
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 flap, the Dell 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:
