Only optical interfaces support ALS. Electrical interfaces do not support ALS.
– When optical interfaces transmit services unidirectionally, they do not support ALS.
– The hardware must provide support for the software to detect the LOS on an optical
interface and control the laser on an interface.
The link aggregation group does not support ALS.
