Cisco Systems 15216 EDFA2 manual Loss of Output Power Alarm Setpoint

Chapter 5 SNMP MIB Installation and Configuration

Retrieving Information

F I N A L D R A F T - C I S C O C O N F I D E N T I A L

Displays output power value in milliwatts.

The snmp row display local cerent15216EdfaOverallStatusGroup command displays the

ONS 15216 EDFA2 output power value and additional pump status. For information about all of the parameters in the cerent15216EdfaOverallStatusGroup table, refer to Table 5-8 on page 5-17.

5.6.7.1.2 OutPowerdBm

Command snmp attribute get local cerent15216EdfaOutPowerdBm

Syntax Description snmp attribute get local cerent15216EdfaOutPowerdBm

Displays output power value in dBm. This command displays loss of output power value and additional pump status data. The dBm units are converted from mW to dBm, so theses values could be slightly different due to rounding error.

For information about all of the parameters in the cerent15216EdfaOverallStatusGroup table, refer to Table 5-8 on page 5-17.

5.6.7.2 Loss of Output Power Alarm Setpoint

5.6.7.2.1 LpoutSetpoint

Command snmp attribute get local cerent15216EdfaLpoutSetpoint

Syntax Description snmp attribute get local cerent15216EdfaLpoutSetpoint

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 the Cisco TAC to determine threshold value for your application. As a guideline, Cisco recommends that loss of output power alarm threshold value be set at 1 dB below the current output power level of the amplifier.

When the ONS 15216 EDFA2 is set to Constant Gain Temperature Compensated mode (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 5-14 on page 5-28). This command returns the current alarm threshold default values.
