als restart pulse-interval

Function

The als restart pulse-interval command sets the ALS pulse interval for the laser of an optical module.

The undo als restart pulse-interval command restores the default ALS pulse interval of the laser of an optical module.

By default, the ALS pulse interval of the laser is 100s.

Format

Usage Guidelines

In automatic restart mode, the ALS pulse interval affects the frequency of detecting the LOS on the interface. A long ALS pulse interval is beneficial for energy saving, but the fiber link recovery cannot be detected in a timely manner. In contrary, a short ALS pulse interval wastes power but the fiber link recovery can be detected immediately.

Example

# Set the ALS pulse interval of lasers on GigabitEthernet0/0/1 to 150s.
