The interface view is displayed.
Step 3 Run:
als restart pulse-interval pulse-interval
The ALS pulse interval of the laser on the interface is set.
By default, the ALS pulse interval is 100s.
Step 4 Run:
als restart pulse-width pulse-width
The ALS pulse width of the laser on the interface is set.
By default, the ALS pulse width is 2s.

9.3.6 Checking the Configuration

After ALS is configured, you can the ALS configuration on a specified interface or in a specified
slot, including the ALS status, laser status, ALS restart mode, and ALS pulse interval and width.
Prerequisite
The ALS configurations are complete on the S5700.

9.4 Configuration Examples

This section provides a configuration example of ALS.

9.4.1 Example for Configuring ALS

Through the ALS function, a laser can automatically stop sending pulses when a link is faulty
and recover pulse transmission after the link is recovered.
Networking Requirements
As shown in
Switch B, GE 0/0/1 of Switch A and Switch B are connected through a fiber.
When data transmission is interrupted by faults occurred on the fiber link, if the laser of the
optical module sends pulses continuously, the energy is wasted and potential risks are caused.
After ALS is enabled on both interfaces of the fiber link, the laser stops sending pulses if a fault
occurs on the fiber link. If the faulty link is recovered, the laser starts to send pulses.
