Example for Configuring ALS

Networking Requirements

As shown in Figure 5-1, XGE0/0/1 on AP connects to GE0/0/1 on SwitchB through optical fibers.

When a link fails, the laser on the optical module is required to automatically stop sending pulses and recover pulse sending after the link is recovered.

Configuration Roadmap
The configuration roadmap is as follows:
  1. Enable ALS on the interface so that the laser automatically stops sending pulses when a link fails.

  2. Set the restart mode of the laser to automatic restart mode so that the laser sends pulses again after the link is recovered.

Procedure

  1. Configure ALS on the interface and the restart mode of the laser.

    # Enable ALS on interfaces XGE0/0/1 of AP and set the restart mode of the laser to automatic restart.

    <Huawei> system-view
    [Huawei] sysname AP
    [AP] interface xgigabitethernet 0/0/1
    [AP-XGigabitEthernet0/0/1] als enable
    [AP-XGigabitEthernet0/0/1] undo als restart mode manual
    

    # Enable ALS on interfaces GE0/0/1 of SwitchB and set the restart mode of the laser to automatic restart.

    <Huawei> system-view
    [Huawei] sysname SwitchB
    [SwitchB] interface gigabitethernet 0/0/1
    [SwitchB-GigabitEthernet0/0/1] als enable
    [SwitchB-GigabitEthernet0/0/1] undo als restart mode manual
    

  2. Verify the configuration.

    # Check ALS configurations on interfaces of AP and SwitchB.
