Version Description
7.5.1.0 Introduced on the C-Series.
7.4.1.0 Introduced on the E-Series.
Usage
Information
With each flap, Dell EMC 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
DellEMC(conf-if-gi-1/10)# dampening 20 800 4500 120
DellEMC(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.
