Hi thank you.
What I try to do is to simulate an unidirectionnal link failure (for OAM LFM tests). So I'm not sure that there is a way to disable ALS.

A log message is also generated that lets you know that RX has fallen below a certain threshold and the transmitter is being shut down. No configuration is required to make this happen. I suspect this would be reliant on you using Juniper "certified" optics though as you'd need digital diagnostics.
