Scenes
You are the company's network administrator. Now the company network is an Ethernet environment composed of two switches. In the figure, the router simulates a computer in the network, and R3 is a server. In order to optimize this network, you need to increase the speed and reliability of the link connecting S1 and S2.
Learning tasks
Step 1. Basic configuration and IP addressing
Configure IP addresses and masks for all devices.
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R1
[R1]interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1]ip address 10.0.10.1 24
[R1-GigabitEthernet0/0/1]quit
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R2
[R2]interface GigabitEthernet 0/0/1

[R2-GigabitEthernet0/0/1]quit
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R3
[R3]interface GigabitEthernet 0/0/2
[R3-GigabitEthernet0/0/2]ip address 10.0.10.3 24
[R3-GigabitEthernet0/0/2]quit
Give the switch a name.
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname S1
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname S2
Step 2. Eth-trunk link aggregation
Eth-trunk can bundle two or more links into one link to improve link bandwidth and reliability. Adding the G0/0/9 and G0/0/10 interfaces of S1 and S2 to the same Eth-trunk group can meet enterprise requirements.
Create an Eth-trunk interface.
[S1]interface Eth-Trunk 1
[S1-Eth-Trunk1]
[S2]interface Eth-Trunk 1
[S2-Eth-Trunk1]
Configure the working mode of the Eth-trunk as LACP.
[S1-Eth-Trunk1]mode lacp
[S1-Eth-Trunk1]quit
[S2-Eth-Trunk1]mode lacp
[S2-Eth-Trunk1]quit
Add the G0/0/9 and G0/0/10 interfaces of S1 and S2 to the Eth-trunk interface.
[S1]interface GigabitEthernet 0/0/9
[S1-GigabitEthernet0/0/9]eth-trunk 1
[S1-GigabitEthernet0/0/9]quit
[S1]interface GigabitEthernet 0/0/10
[S1-GigabitEthernet0/0/10]eth-trunk 1
[S1-GigabitEthernet0/0/10]quit
[S2]interface GigabitEthernet 0/0/9
[S2-GigabitEthernet0/0/9]eth-trunk 1
[S2-GigabitEthernet0/0/9]quit
[S2]interface GigabitEthernet 0/0/10
[S2-GigabitEthernet0/0/10]eth-trunk 1
[S2-GigabitEthernet0/0/10]quit
Run the dispay eth-trunk command to check the configuration.
[S1]display eth-trunk
Eth-Trunk1's state information is:
Local:
LAG ID: 1 WorkingMode: LACP
Preempt Delay: Disabled Hash arithmetic: According to SIP-XOR-DIP
System Priority: 32768 System ID: d0d0-4ba6-aab0

GigabitEthernet0/0/10 32768 d0d0-4ba6-ac20 32768 2 305 10111100
The output information shows that the link operation mode is LACP mode, and the maximum number of active interfaces is 8 links. Both G0/0/9 and G0/0/10 interfaces are active at the same time.
Use the command to change the active interface count threshold.
[S1]interface Eth-Trunk 1
[S1-Eth-Trunk1]max active-linknumber 1
[S1-Eth-Trunk1]quit
[S2]interface Eth-Trunk 1
[S2-Eth-Trunk1]max active-linknumber 1
[S2-Eth-Trunk1]quit
Check the configuration of the Eth-trunk link.
[S1]display eth-trunk 1

GigabitEthernet0/0/10 32768 d0d0-4ba6-ac20 32768 2 305 10100000
The output shows that the status of the G0/0/10 interface changes to Unselect. It implements the function of transmitting data on one link of the Eth-trunk aggregated link and backing up the other link, which improves network reliability.
Verify the function of the backup link by shutting down the G0/0/9 interface of S1.
[S1]interface GigabitEthernet 0/0/9
[S1-GigabitEthernet0/0/9]shutdown
[S1-GigabitEthernet0/0/9]quit
View Eth-trunk link information.

From the output information, it can be seen that G0/0/9 on the Eth-trunk link has changed to the Unselected state, and G0/0/10 is automatically converted from the Unselected state to the Selected state to continue transmitting data. It can be seen that the link backup function is realized.
