Usage Guidelines

The ALS pulse width refers to the period between rising edges of pulses. A short ALS pulse width is beneficial for energy saving, but the fiber link recovery cannot be detected immediately. In contrary, a long ALS pulse width consumes more power but the fiber link recovery can be detected immediately.

Example

# Set the ALS pulse width on interfaces XGigabitEthernet0/0/1 to 3s.

<Huawei> system-view
[Huawei] interface xgigabitethernet 0/0/1
