Release Information

Statement introduced in Junos OS Releases 15.1F6 and 17.1R1.

Description

Configure the threshold crossing alerts (TCA)s for the integrated photonic line card (IPLC).

TCAs can give the management system an early indication as to the state of the associated entity when it crosses a certain threshold. The timely detection of TCAs is essential to proactively manage the IPLC modules. TCAs are not an indication of a fault, but rather an indication that the entity may be close to a fault. You can choose which TCAs you want monitored by enabling the TCA. You can either keep the default threshold settings or modify the settings.

You can enable TCAs on the IPLC for the performance monitors listed in Table 1.
