■ Configuring Bias Current Threshold
Follow these steps to configure the threshold of the DDM bias current 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 bias_current_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 mA. The valid values are from 0 to 131.
Step 4 show ddm configuration bias_current
Display the DDM bias current 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 bias
current as 120 mA.
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/17
Switch(config-if)#ddm vlotage_threshold high_alarm 120
Switch(config-if)#show ddm configuration bias_current
