Chapter 5 SNMP MIB Installation and Configuration
Retrieving Information
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.
