This DDM UI specification describes the Digital Diagnostic Monitoring functionality and specifications based on SFF-8472
standard. Functions of this software module apply on L2 and L3 Ethernet switches, which contain SFP interface.
The Digital Diagnostic Monitoring (DDM) commands in the Command Line Interface (CLI) are listed (along with the
appropriate parameters) in the following table.

config ddm ports
Purpose
Used to configure the DDM settings of the specified ports.
Syntax
config ddm ports [<portlist> | all] temperature_threshold { high_alarm < float > |
low_alarm < float > | high_warning < float > | low_warning < float >} (1)
Description
The command is used to configure the DDM settings of the specified ports.
Parameters
<portlist>
- Enter the range of ports to be configured here.
all
- Specify that all the optic ports’ operating parameters will be configured.
temperature_threshold
- Specify the threshold of the optic module’s temperature in
centigrade. At least one parameter shall be specified for this threshold.
high_alarm
- Specify the high threshold for the alarm. When the operating parameter rises
above this value, the action associated with the alarm is taken.
<float>
- Enter the high threshold alarm value used here.
low_alarm
- Specify the low threshold for the alarm. When the operating parameter falls
below this value, the action associated with the alarm is taken.
<float>
- Enter the low threshold alarm value used here.
high_warning
- Specify the high threshold for the warning. When the operating parameter
rises above this value, the action associated with the warning is taken.
<float>
- Enter the high threshold warning value here.
low_warning
- Specify the low threshold for the warning. When the operating parameter falls
below this value, the action associated with the warning is taken.
<float>
- Enter the low threshold warning value here.
voltage_threshold
- Specify the threshold of optic module’s voltage.
