Configuring DDM (Only for Certain Devices) DDM Configuration
Step 3 ddm temperature_threshold { high_alarm | high_warning | low_alarm | low_warning }
value
high_alarm: Specify the high threshold for the alarm. When the operating parameter rises
above this value, action associated with the alarm will be taken.
high_warning: Specify the high threshold for the warning. When the operating parameter
rises above this value, action associated with the warning will be taken.
low_alarm: Specify the low threshold for the alarm. When the operating parameter falls
below this value, action associated with the alarm will be taken.
low_warning: Specify the low threshold for the warning. When the operating parameter falls
below this value, action associated with the warning will be taken.
value
: Enter the threshold value in Celsius. The valid values are from -128 to 127.996.
Step 4 show ddm configuration temperature
Display the DDM temperature threshold on the SFP ports.
Step 5 end
Return to Privileged EXEC Mode.
Step 6 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to set SFP port 1/0/27’s high alarm temperature
threshold as 110 Celsius.
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/27
Switch(config-if)#ddm temperature_threshold high_alarm 110
Switch(config-if)#show ddm configuration temperature
Temperature Threshold(Celsius) :
High Alarm Low Alarm High Warning Low Warning
Gi1/0/27 110.000000 -- -- --
