tca

Syntax

Hierarchy Level

Description

TCAs can give the management system an early indication as to the state of the associated entity when it crosses a certain threshold. TCAs can be set for both minimum and maximum values for gauges and only maximum values for counters. The timely detection of TCAs is essential to proactively manage the interface. 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 change the settings.

Enable threshold crossing alerts (TCAs) for the following:

• Optical channel data unit (ODU)

• Optical channel transport unit (OTU)

• Laser power

• Laser temperature

Default

By default, TCAs are not enabled.
