Usage Information With each ap, Dell Networking OS penalizes the interface by assigning a penalty (1024) that decays
exponentially depending on the congured 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 congured 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 trac for other interfaces.
Example
Dell(conf-if-te-1/10)# dampening 20 800 4500 120
Dell(conf-if-te-1/10)#
Related Commands
• clear dampening — clear the dampening counters on all the interfaces or just the specied 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.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE 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
