Performance monitoring for NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards

Updated: October 7, 2026

Want to summarize with AI?

This section explains how performance monitors operate on NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L line cards, enabling service providers to gather, report, and optimize key optical performance parameters.

Table 1. Feature History
Feature Name	Release Information	Feature Description
Supported Functionalities of CCMD-16-C and CCMD-16-L Line Cards	Cisco IOS XR Release 7.11.1	Supported Functionalities of CCMD-16-C and CCMD-16-L Line Cards: The software supports Variable Optical Attenuator (VoA), power monitoring and reporting of parameters to the controllers at the OCH and OMS level. It helps in configuring the amplifier parameters for optimizing signal transmissions. The software also supports in-band and out-of-band tone detection and monitoring and reporting of alarms.

Service providers use performance monitoring (PM) parameters to gather and store data, set thresholds, and report performance information for early detection of network issues.

You can configure and retrieve PM counters for the OCH and OMS controllers in 30-second, 15-minute, or 24-hour intervals, or in a flexible 10-second bin interval. These parameters simplify troubleshooting and enhance the value of data collected directly from the equipment.

PM parameters supported on OMS controller

These are the PM parameters supported on the OMS controller:

Configure PM parameters for NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards

Follow these steps to configure the minimum and maximum thresholds for individual parameters.

Procedure

Run the controller controllertype R/S/I/P pm {30-sec | 15-min | 24-hour} optics threshold { parameter-name} {max|min} {value} command to configure minimum and maximum thresholds for individual performance monitoring parameters.
Example:

This sample displays the performance monitoring parameters of the OMS controller.
```
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:(config)#controller oms 0/1/0/0 pm 30-sec optics threshold opt min < value >
RP/0/RP0/CPU0:ios(config)#commit
```
This sample displays the performance monitoring parameters of the OCH controller.
```
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:(config)#controller och 0/1/0/1 pm 30-sec optics threshold opt min < value >
RP/0/RP0/CPU0:ios(config)#commit
```
Run the controller controllertype R/S/I/P pm {30-sec | 15-min | 24-hour} optics report { parameter-name} {min-tca|max-tca} command to enable reporting of threshold crossing alarms for individual parameters.
Run the commit command to save the changes.

Use this task to view the performance monitoring parameters for OMS and OCH controllers.

Procedure

Run the show controllers controllertype R/S/I/P pm { current | history } { 30 sec | 15-min | 24-hour | flex-bin } optics { linenumber } bucketvalue command to view PM parameters for the OMS and OCH controllers.

Example:
