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.
Example
Dell(conf-if-gi-1/10)# dampening 20 800 4500 120
Dell(conf-if-gi-1/10)#

Commands
• clear dampening — clear the dampening counters on all the interfaces or just the specified interface.
• show interfaces dampening — display interface dampening information.
default interface
Reset a physical interface to its factory default settings.
Syntax
default interface interface-type slot/port - range
Parameters
interface-type
slot/port
Enter the interface type and slot/port information:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port information.
range
• For non-ON platforms, you can specify multiple ports as slot/port-range. For
example, if you want to display information corresponding to all ports between 1 and 4,
specify the port range as show interfaces interface-type 1/1 - 4.
• For ON platforms, you can specify multiple ports as slot/port/[subport] -
slot/port/[subport]. For example, if you want to display information
corresponding to all ports between 1 and 4, specify the port range as show
interfaces interface-type 1/1/1 - 1/1/4.

OS Command Line Reference Guide.
Version Description
9.10(0.0) Introduced on the S3100 series.
9.9(0.0) Introduced on the S4810, S4820T, S3048-ON, S4048-ON, S5000, S6000, S6000–ON,

Usage Information
Use the default interface command to set a Gigabit Ethernet, 10- Gigabit Ethernet, or 40-Gigabit Ethernet
interface to its factory-default state. By default, a physical interface is disabled (shutdown) with no assigned IP
address or switchport (no ip address). This command removes all software settings and all L3, VLAN, VXLAN, and
port-channel configurations on a physical interface.
