Figure 9-3 ALS application
GE0/0/1 GE0/0/1
SwitchA SwitchB
Configuration Roadmap
The configuration roadmap is as follows:
1. Enable ALS on GE 0/0/1 on Switch A and Switch B.
2. Configure the lasers of GE 0/0/1 on Switch A and Switch B to work in automatic restart
mode.
3. Set the ALS pulse intervals and widths of the lasers of GE 0/0/1 on Switch A and Switch
B.
Data Preparation
To complete the configuration, you need the following data:
l ALS pulse interval and width of the laser of the optical module on GE 0/0/1 of Switch A
l ALS pulse interval and width of the laser of the optical module on GE 0/0/1 of Switch B
Procedure
Step 1 Enable ALS on GE 0/0/1 of Switch A, configure the laser of the interface to work in automatic
restart mode, and set the ALS pulse interval and width to 200s and 3s.
# Enable ALS.
<SwitchA> system-view
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] als enable
# Set the ALS pulse interval and width of the laser.
[SwitchA-GigabitEthernet0/0/1] undo als restart mode manual
[SwitchA-GigabitEthernet0/0/1] als restart pulse-interval 200
[SwitchA-GigabitEthernet0/0/1] als restart pulse-width 3
Step 2 Enable ALS on GE 0/0/1 of Switch B, configure the laser of the interface to work in automatic
restart mode, and set the ALS pulse interval and width to 200s and 3s.
# Enable ALS.
<SwitchB> system-view
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] als enable
# Set the ALS pulse interval and width of the laser.
[SwitchB-GigabitEthernet0/0/1] undo als restart mode manual
[SwitchB-GigabitEthernet0/0/1] als restart pulse-interval 200
[SwitchB-GigabitEthernet0/0/1] als restart pulse-width 3
Step 3 Verify the configuration.
