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, 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:
• 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.
