Command snmp attribute get local cerent15216EdfaLpoutHysteresis
Syntax Description snmp attribute get local cerent15216EdfaLpoutHysteresis
This attribute is not required when operating in factory default Constant Gain Temperature Compensated
mode. Setting of the loss of output power alarm deviation is only necessary when the amplifier is used
in Constant Output Power or Constant Pump Power modes of operation.
This attribute is used to set the amount by which the output power must increase from the threshold
setpoint before the alarm is cleared. This attribute, in conjunction with the loss of output power alarm
threshold and deviation, enables efficient processing and clearing of the alarm condition.
Typically, network operations personnel should set the loss of output power alarm hysteresis 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 the hysteresis value for your application. As a guideline, Cisco
recommends that loss of output power alarm hysteresis value be set at 0.2 dB. The module clears the
alarm if it detects a signal level of 0.2 dB above the current output power alarm level threshold value set
for the amplifier.
When 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 deviation and other power and temperature alarm data, use the snmp table display local
cerent15216EdfaCfgGroup command as shown in
the current alarm threshold default values.
To set the loss of output power alarm hysteresis when ONS 15216 EDFA2 is configured for operation in
either Constant Output Power mode or Constant Pump Power mode, type snmp attribute set local
cerent15216EdfaLpoutHysteresis at the command prompt followed by a number. Valid entries are
between 0 and 1000 and are in dB times 100. For example, if the loss of output power hysteresis required
were 0.2 dB, the number input as loss of output power alarm hysteresis would be 200.
The user is prompted to modify the attribute. If changes are not required, press Enter to return to
command prompt.

5.6.8 Database Backup and Restore

The configuration information for the ONS 15216 EDFA2 can be saved in a file for later use or to
configure other ONS 15216 EDFA2 units. This file contains manufacturing information about the unit
that is being backed up (such as part number and serial number), setup information for the unit (such as
IP address and host name), all configuration information (such as alarm thresholds and pump mode), and
the user database.
