Enabling and Configuring Thresholds on the Integrated Photonic Line Card Performance Monitors

Performance monitors monitor the health of the IPLC modules at various points on the IPLC hardware based on threshold crossing alerts (TCA)s. This topic describes how to enable and configure TCAs for the IPLC performance monitors.

TCAs can give the management system an early indication as to the state of the associated entity when it crosses a certain threshold. TCAs are alarms that are activated when a certain configurable threshold—near-end measurement threshold or far-end measurement threshold—is crossed and remains so until the end of the 15-minute interval and the 24-hour interval for parameters such as OTU and ODU.

The timely detection of TCAs is essential to proactively manage an IPLC. TCAs are not an indication of a fault, but rather an indication that the entity may be close to a fault. You can enable the TCA that you want monitor. You can keep the default threshold settings or change the settings.

Note

By default, TCAs are disabled.

The IPLC supports the performance monitors listed in Table 1.

To configure a TCA, specify the TCA low and high thresholds and then enable the TCA. This example enables the osc-rx-power-high-tca and osc-rx-power-low-tca TCA in the OSC RX power performance monitor.

To configure a TCA:

Navigate to the IPLC TCA configuration. For example:
Configure the 15-minute, low threshold. For example:
Configure the 15-minute, high threshold. For example:
Configure the 24-hour, low threshold. For example:
Configure the 24-hour, high threshold. For example:

Verify the configuration.

Save your configuration.
You can use the following commands to view information about performance monitors and TCA alarms:
- To view the status of the IPLC module, use the show chassis fpc optical-properties status command.
- To view the current alerts, use the show chassis fpc optical-properties pm-current command.
- To display alerts in 15-minute intervals, use the show chassis fpc optical-properties pm-interval command.
- To view the 24-hour alerts, use the show chassis fpc optical-properties pm-currentday command.
- To view the alerts from the previous day, use the show chassis fpc optical-properties pm-previousday command.
