Understanding the Performance Monitors and TCAs for IPLCs
Performance monitors enable you to examine and diagnose the health, working capacity, operational efficiency, and the traffic-handling condition of the integrated photonic line cards modules (IPLCs) at various points on the optical IPLC hardware. You can enable configure threshold-crossing alarms (TCA) for the optical IPLC performance monitors. 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 for 15 minutes
The IPLC supports the optical performance monitors listed in Table 1.
