Loss of Output Power Value (Output Power)
OutPoweruW
Command: snmp attribute get local cerent15216EdfaOutPoweruW
Syntax: snmp attribute get local cerent15216EdfaOutPoweruW
Description: Displays loss of output power value in microwatts.
The snmp row display local cerent15216EdfaOverallStatusGroup command displays
the Cisco ONS 15216 EDFA2 loss of output power value and additional pump status. For
information about all of the parameters in the cerent15216EdfaOverallStatusGroup table,
refer to Table 5-8.
OutPowerdBm
Command: snmp attribute get local cerent15216EdfaOutPowerdBm
Syntax: snmp attribute get local cerent15216EdfaOutPowerdBm
Description: Displays loss of output power value in dBm. This command displays loss of output power
value and additional pump status data.
For information about all of the parameters in the cerent15216EdfaOverallStatusGroup table, refer to
Table 5-8.
Loss of Output Power Alarm Setpoint
LpoutSetpoint
Command: snmp attribute get local cerent15216EdfaLpoutSetpoint
Syntax: snmp attribute get local cerent15216EdfaLpoutSetpoint
Description: This attribute notifies network operations personnel notification if the output power of the
ONS 15216 EDFA2 drops below a level that impacts proper operation of the optical
network.
Typically, network operations personnel should set the loss of output power alarm
threshold at a value that is appropriate for the intended network application so that the
alarm condition is meaningful. Consult with a Cisco Systems Engineer to determine
threshold value for your application. As a guideline, Cisco recommends that loss of output
power alarm threshold value be set at 1 dBm below the current output power level of the
amplifier.
When the ONS 15216 EDFA2 is set to constant gain operation (factory default), the value
for loss of output power alarm threshold cannot be changed. To display the loss of output
power alarm threshold and other power and temperature alarm data, use the snmp table
display local cerent15216EdfaCfgGroup command (shown in Example 5-12). This
command returns the current alarm threshold default values.
