2.2.4 Viewing DDM Configuration
Follow these steps to view the DDM configuration.
Step 1 configure
Enter global configuration mode.
Step 2 show ddm configuration { state | temperature | voltage | bias_current | tx_power | rx_power}
state: Displays the DDM configuration state.
temperature: Displays the threshold of the DDM temperature value.
voltage: Displays the threshold of the DDM voltage value.
bias_current: Displays the threshold of the DDM bias current value.
tx_power: Displays the threshold of the DDM Tx Power value.
rx_power: Displays the threshold of the DDM Rx Power value.
Step 3 end
Return to Privileged EXEC Mode.
Step 4 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to view SFP ports‘ Rx power threshold.
Switch#configure
Switch(config)#show ddm configuration rx_power
Rx Power Threshold(mW) :
High Alarm Low Alarm High Warning Low Warning
