Configuring DDM DDM Configuration 2.2.6 Configuring Tx Power Threshold Follow these steps to configure the threshold of the DDM Tx power on the specified SFP port. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 configure Enter global configuration mode. 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. ddm tx_power_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 mW. The valid values are from 0 to 6.5535. show ddm configuration tx_power Display the DDM tx power threshold on the SFP ports. end Return to Privileged EXEC Mode. copy running-config startup-config Save the settings in the configuration file. The following example shows how to set SFP port 1/0/17's high alarm threshold Tx power as 6 mW.
