Setting the Restart Mode of the Laser

Setting the Restart Mode of the Laser

Context

After ALS is enabled, the laser is automatically shut down when a fiber is not properly installed on an interface or the connected optical link fails. However, the laser still needs to send pulses at a certain interval. When a fiber is installed on an interface or the connected optical link recovers, the laser is automatically restored to set up a connection for data communication. Therefore, you need to configure the restart mode of the laser after ALS is enabled.

The laser of an optical module works in automatic restart mode or manual restart mode.
  • Automatic restart mode: The laser automatically sends a pulse at an interval to detect whether the link recovers.

  • Manual restart mode: When a fiber is installed or an optical link recovers, you must start the laser manually. Then the laser sends a pulse to detect whether the link recovers.

By default, a laser works in automatic restart mode.
NOTE:

When ALS is enabled and the manual restart mode is configured on physical stack member interfaces, the local interface becomes Up and the peer interface becomes Down if the shutdown and then undo shutdown commands are executed on the peer interface. The two interfaces become Up after the als restart command is executed on the local interface.

Procedure

  • Configure automatic restart mode

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface—number

      The interface view is displayed.

    3. Run als restart mode automatic

      The laser of the optical module is configured to work in automatic restart mode.

      By default, a laser works in automatic restart mode.

    4. Run commit

      The configuration is committed.

  • Configure manual restart mode

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface—number

      The interface view is displayed.

    3. Run als restart mode manual

      The laser of the optical module is configured to work in manual restart mode.

    4. Run commit

      The configuration is committed.

    5. Run als restart

      The laser of the optical module is started manually.

      After a fiber is installed on the interface or the connected optical link recovers, you must use this command to manually start the laser of the optical module.
