Verify Raman tuning configuration and status

Updated: February 5, 2026

Overview

This topic explains how to verify Raman tuning configuration and operational status by using available verification tasks to review tuning state, historical events, and Raman pump parameter values, helping you confirm correct operation and identify potential issues.

Use the following tasks to verify Raman tuning configuration, review tuning history, and inspect Raman pump values.

Verify Raman tuning configuration

Use this task to verify Raman tuning configuration to confirm the current tuning state and the configured gain-related values.

  • Check whether Raman tuning is measuring, calculating, optimizing, tuned, blocked, or disabled.

  • View the Raman tuning parameter values reported by the controller.

Raman tuning status indicates the current state of the Raman tuning process. The output also displays key parameter values, such as target gain and achieved gain, and shows conditions that can prevent tuning.

Follow these steps to verify Raman tuning configuration.

Procedure

Verify Raman tuning status and parameter values.

The entries highlighted in bold show the Raman tuning status and Raman tuning parameter values.

Example:

/*Verify Raman tuning status if All Controllers*/
RP/0/RP0/CPU0:ios#show olc raman-tuning 
Tue Mar 21 06:11:36.944 UTC
Controller : Ots0/0/0/0
Raman-Tuning Status : TUNED
Tuning Complete Timestamp : 2023-03-20 07:54:00
Estimated Max Possible Gain : 19.8 dB
Raman Gain Target : 16.0 dB
Gain Achieved on Tuning Complete : 15.7 dB

/*Verify Raman tuning status on a specific controller*/
RP/0/RP0/CPU0:ios#show olc raman-tuning controller ots 0/0/0/0
Tue Mar 21 06:13:26.535 UTC
Controller : Ots0/0/0/0
Raman-Tuning Status : TUNED
Tuning Complete Timestamp : 2023-03-20 07:54:00
Estimated Max Possible Gain : 19.8 dB
Raman Gain Target : 16.0 dB
Gain Achieved on Tuning Complete : 15.7 dB

For more information about Raman tuning status, see Raman tuning status. For information about Raman tuning parameters, see Raman tuning parameters.

The system displays the Raman tuning status and the Raman tuning parameter values for all controllers or for the specified controller.

What to do next

If tuning is blocked or disabled, correct the condition and re-run the verification command.

View detailed Raman tuning status

View detailed Raman tuning status information to understand the outcome of previous tuning attempts.

  • Identify the reason and timestamp of the last Raman tuning failure.

  • Review the last successful Raman tuning gain and timestamp.

In addition to the current Raman tuning state, the system maintains historical information about previous tuning attempts. This information helps troubleshoot tuning failures and verify successful tuning history.

Follow these steps to view detailed Raman tuning status.

Procedure

View the detailed Raman tuning status.

The entries highlighted in bold show the previous Raman tuning failure reason and timestamps.

The system displays detailed Raman tuning status, including failure reasons, timestamps, and successful tuning history.

View Raman pump values

View individual Raman pump values and related parameter details to verify current pump power, configured pump values, and safety controls.

  • Confirm composite Raman power and individual pump measured powers.

  • Verify Raman safety control mode, OSRI status, and APR state.

  • Compare configured pump values with measured values reported by the controller.

Raman pump values and parameter statistics help you assess amplifier health and safety conditions. The controller reports alarm statistics, measured pump powers, composite power, and the configured pump values. Use this task when troubleshooting Raman-related alarms, validating pump configuration, or confirming safety lock and OSRI status.

Follow these steps to view individual Raman pump values and related parameter details.

Procedure

Show Raman pump values and parameter details for the OTS controller.

The entries highlighted in bold show the Raman safety/OSRI status, composite power, and the measured pump powers. The configured pump values are shown in the Configured Parameters section.
