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:
● 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
Dell(conf-if-te-3/2)#dampening 20 800 4500 120
Dell(conf-if-te-3/2)#

Usage
Information
● Spaces between characters are not preserved after entering this command unless you enclose the
entire description in quotation marks (“desc_text”).
● Entering a text string after the default vlan-id command overwrites any previous text string
configured as the description.
● The show tdr and default vlan-id commands are the only commands that you can configure
on an interface that is a member of a port-channel.
● Use the show interfaces description command to display descriptions configured for each
interface.
