Version Description
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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)#
Related Commands
clear dampening — clears the dampening counters on all the interfaces or just the specified interface.
show interfaces dampening — displays 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.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigabitEthernet
then the slot/port information.
range 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.
Defaults None
