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
This command only works on ports that the system recognizes as CX4 ports. The figures below shows an
attempt to configure an XFP port with the command after inserting a CX4 converter into the port.
For details about using XFP ports with CX4 cables, refer to your FN IOM switch hardware guide.
Example
(Unsuccessful)
Dell#show interfaces tengigabitethernet 0/26 | grep "XFP type"
Pluggable media present, XFP type is 10GBASE-CX4
Dell(conf-if-te-0/26)#cx4-cable-length short
% Error: Unsupported command.
Dell(conf-if-te-0/26)#cx4-cable-length medium
% Error: Unsupported command.
Dell(conf-if-te-0/26)#cx4-cable-length long
% Error: Unsupported command.
Dell(conf-if-te-0/26)#
Example
(Successful)

Commands
show config – displays the configuration of the selected interface.
dampening
Configure dampening on an interface.
Syntax
dampening [[[[half-life] [reuse-threshold]] [suppress-threshold]] [max-
suppress-time]]
To disable dampening, use the no dampening [[[[half-life] [reuse-threshold]]
[suppress-threshold]] [max-suppress-time]] command.
Parameters
half-life Enter the number of seconds after which the penalty is decreased. The penalty
decreases half after the half-life period expires. The range is from 1 to 30 seconds.
The default is 5 seconds.
reuse-threshold Enter a number as the reuse threshold, the penalty value below which the interface
state is changed to “up”. The range is from 1 to 20000. The default is 750.
suppress-
threshold
Enter a number as the suppress threshold, the penalty value above which the
interface state is changed to “error disabled”. The range is from 1 to 20000. The
default is 2500.
max-suppress-
time
Enter the maximum number for which a route can be suppressed. The default is
four times the half-life value. The range is from 1 to 86400. The default is 20
seconds.
Defaults Disabled.
