■ Configuring Voltage Threshold
Follow these steps to configure the threshold of the DDM voltage on the specified SFP
port.
Step 1 configure
Enter global configuration mode.
Step 2 interface { fastEthernet
port | range fastEthernet port-list | gigabitEthernet port | range
gigabitEthernet
port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list }
Enter interface configuration mode.
Step 3 ddm voltage_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 V. The valid values are from 0 to 6.5535.
Step 4 show ddm configuration voltage
Display the DDM voltage threshold of 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 threshold voltage as
5 V.
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/27
Switch(config-if)#ddm vlotage_threshold high_alarm 5
Switch(config-if)#show ddm configuration voltage
Voltage Threshold(V) :
High Alarm Low Alarm High Warning Low Warning
