Hierarchy Level


Enable threshold crossing alerts (TCAs) for the following:

  • Laser power

  • Laser temperature


By default, TCAs are not enabled.


tca-identifier —At the optics-options hierarchy level, it can be one of the following:

  • carrier-frequency-offset-high-tca—Carrier frequency high threshold setting trigger

  • carrier-frequency-offset-low-tca—Carrier frequency low threshold setting trigger

  • rx-power-high-tca—Rx power high threshold setting trigger

  • rx-power-low-tca—Rx power low threshold setting trigger

  • temperature-high-tca—Temperature high threshold setting trigger

  • temperature-low-tca—Temperature low threshold setting trigger

  • tx-power-high-tca—Tx power high threshold setting trigger

  • tx-power-low-tca—Tx power low threshold setting trigger

enable-tca | no-enable-tca—To enable or disable the threshold crossing alert.

threshold | threshold-24hrs:

  • threshold number—Set the 15-minute interval threshold.

  • threshold-24hrs number—Set the 24-hour interval threshold.
