The MIB definitions for ONS-15501 Optical Amplifier.

Gives the name of the software programmed on flash bank one.

Gives the name of the software programmed on flash bank two.

Gives the name of the software programmed on flash bank three.

Used to control the image download to the flash banks. NOTE: Read on this attribute returns the last t/ftp command, without login/password. For s/w release 4.0 and above, the value read back includes the Kilo-Bytes downloaded for last download command. It is the size of file downloaded (in KB), if the download has completed. If a download is in progress this value would correspond to Kilo-Bytes successfully downloaded so far. For set the string syntax is one of the following a. abort - Aborts the current download b. ftp::::::[:passive] - Download image using ftp c. tftp::: - Download image using tftp where - is t/ftp server name - is login to be used for ftp (default anonymous) - password for the login name for ftp (default - no passwd - passwd is empty string) - path to be given on ftp prompt for cd (default - skip cd command ) - name of the file to be downloaded and burnt to the flash - NO DEFAULTS - because the filename is used as distinguishing versions there are no defaults for this command. For TFTP Path information is part of the filename - which flash has to be burnt [1|2|3] NOTE: Burn to active bank fails passive - if `passive` is specified, ftp is done using passive mode (provided for FTP download across firewall). NOTE: None of the fields should contain ':' within them, as it is used as field separator.

Show currently active image's bank number. This may be different from ons15501SysConfiguredActiveImage, if a. The image on ons15501SysConfiguredActiveImage did not boot properly. b. User chose another bank during bootup, using the serial console port.

A ',' separated list of managers that will receive the Traps. If a specific host should receive the traps sent from this unit, it should be added to the list using CLI. Up to 16 managers can be present in this list.

Denotes the FTP/TFTP status. Please refer to the description of Ons15501ImageDnLoadStatus for a list of supported values

Set/Show configured value for flash-bank number to be used on reboot. A set on this attribute will result in a reboot of the system. To restart the system, write back the same value as the one read from it (or from ons15501SysDevActiveImage).

This attribute gives the time-stamp when one or more of ons15501InRemoteChassisName, ons15501InRemotePortName, or ons15501InRemoteAgentIpAddr was changed. NMS may use this information to find the latest information if data from remote unit does not match that of this unit.

Manager initialized string value to identify the chassis associated with remote connection for optical input. ons15501InRemoteChassisName would be a ZERO length string if the input link is disabled.

Manager initialized string value to identify the network address to be used to reach the SNMP agent entity containing information about the port and chassis providing optical input. ons15501InRemoteAgentIpAddr would be a 0.0.0.0 if the input link is disabled. To disable the input link entry set ons15501InRemoteChassisName to ZERO length string and ons15501InRemoteAgentIpAddr to 0.0.0.0.

This attribute gives the time-stamp when one or more of ons15501OutRemoteChassisName, ons15501OutRemotePortName, or ons15501OutRemoteAgentIpAddr was changed. NMS may use this information to find the latest information if data from remote unit does not match that of this unit.

Manager initialized string value to identify the chassis associated with remote connection for optical output. ons15501OutRemoteChassisName would be a ZERO length string if the output link is disabled. To disable the output link details set ons15501OutRemoteChassisName to ZERO length string and ons15501OutRemoteAgentIpAddr to 0.0.0.0.

Manager initialized string value to identify the the port (on remote chassis) associated with remote connection for optical output. ons15501OutRemotePortName would be a ZERO length string if the output link is disabled. To disable the output link details set ons15501OutRemoteChassisName to ZERO length string and ons15501OutRemoteAgentIpAddr to 0.0.0.0.

Manager initialized string value to identify the network address to be used to reach the SNMP agent entity containing information about the port and chassis using optical output. ons15501OutRemoteAgentIpAddr would be a 0.0.0.0 if the output link is disabled. To disable the output link entry set ons15501OutRemoteChassisName to ZERO length string and ons15501OutRemoteAgentIpAddr to 0.0.0.0.

Provides the highest severity alarm currently active.

The date and time of the System. The write will not succeed if the administrative state for NTP (ons15501NTPAdminStatus) is 'enabled'. Setting this attribute will autmatically change values for ons15501TrapLogEntryDateAndTime and ons15501ActAlarmDateAndTime.

The optical power being fed into the Amplifier.

Mean value for input optical power. If the input optical power falls below the mean value by more than trigger (see ons15501InputOpticalPowerTrigger) an alarm is generated. The alarm is cleared when the input optical power is back within 90% of trigger from the mean.

Trigger defines the max deviation allowed from the mean, without an alarm being generated. Once an alarm is generated, it is not cleared until the input optical power falls back within 90% of the trigger value from the mean. Please also refer to ons15501InputOpticalPowerMean above.

The measured value for raw optical power being generated at the output of the Amplifier.

The optical signal power at the output of the Amplifier. The value of this attribute triggers the alarm, based on mean value and trigger as defined by ons15501OutputSignalPowerMean and ons15501OutputSignalPowerTrigger. This value is internally calculated using the following formula. ons15501OutputSignalPower = ons15501OpticalPowerGain + ons15501InputOpticalPower At very low ons15501InputOpticalPower (below -16 dBm), the ons15501OutputSignalPower has significant difference from ons15501OutputOpticalPower while at higher input power (ons15501InputOpticalPower) they are closer. Following graph captures the difference (for a 17 dBm EDFA) (dashes '-'/'_' denote optical output power while dots '.' denote signal output power) ^ | .- | .- | .- +5 dBm | .- | .- Optical | _.- power / | _ -. Signal |_ _ - . power | . | . | . -17 dBm +-----------------------+--------------> -29 dBm -10 dBm Input Optical Power

Mean value for output optical power. If the output signal power falls below (or goes above) the mean value by more than trigger (see ons15501OutputSignalPowerTrigger) an alarm is generated. The alarm is cleared when the output optical power is back within 90% of trigger from the mean.

Trigger defines the max deviation allowed from the mean, without an alarm being generated. Once an alarm is generated, it is not cleared until the output signal power falls back within 90% of the trigger value from the mean. Please also refer to ons15501OutputSignalPowerMean above.

The configured value for power gain.

The measured value for power gain. This value does not include the amplification noise that is significant for low input signals.

The gain deviation allowed from the configured gain before an alarm is asserted. The alarm is not cleared, until measured gain(ons15501OpticalPowerGain) is back within 90% of ons15501GainTrigger from configured gain (ons15501ConfigOpticalGain).

The voltage fed through power supply 1. The value of the attribute is 10 times the the value in volts.

The voltage fed through power supply 2. The value of the attribute is 10 times the the value in volts.

Gives the status of the laser pumps.

The ambient temperature for the device.

Mean value for temperature. If the temperature falls below (or goes above) the mean value by more than trigger level (see ons15501DevAmbTempTrigger) an alarm is generated. The alarm is cleared when the temperature is back within 90% of trigger value, from the mean.

Please refer to ons15501DevAmbTempMean above. Trigger defines the max deviation allowed from the mean, without an alarm being generated. Once an alarm is generated, it is not cleared until the temperature falls back within 90% of the value.

Gives the status of power supply one.

Gives the status of power supply two.

The value of ons15501TrapLogEntryIndex, used while logging the most recent trap. Goes back to 1, after reaching the max value. The trap log table is a circular list with the most recent entry at index given by this attribute. On restart of the unit, the value is reset to 1.
