Restrictions on the alarm reversion function of WDM equipment

1. The NE software of WDM equipment in each version supports alarm reversion. The alarm reversion has three modes: disabled (no reversion), manual (permanent reversion), and automatic (one-off reversion).
2. Currently, only the R_LOS and MUT_LOS alarms of WDM equipment support reversion, and no other LOS conditions are available.
3. Alarm reversion takes effect only on the NE software. The actual alarm status still exists on boards. Alarms are saved in the blackboxes of boards and can be queried using a PTP command.
By running the :alm-set-bsrep:bid,enable command, you can also find that alarms are reported from boards to the NE software.
