Huawei Switch Port Configuration Aggregation

To configure an aggregation port on a Huawei switch, create an Eth-Trunk interface, add member ports, configure LACP or manual mode, set interface priorities, and assign VLANs.

Step 1: Prepare Member Interfaces

Before adding interfaces to an Eth-Trunk, ensure that the physical ports are not part of any VLAN or are shut down to avoid broadcast storms. For example, exit VLAN1 or shut down the interface temporarily .

Step 2: Create the Eth-Trunk Interface

Create a logical aggregation interface (Eth-Trunk) and choose the aggregation mode:

• Manual mode: No LACP negotiation; all member links are active.
• LACP mode: Uses Link Aggregation Control Protocol to negotiate active and backup links.

Step 3: Add Member Interfaces

Add the physical interfaces to the Eth-Trunk. Ensure that both ends of the link have the same number of member interfaces, speed, duplex, and flow control settings .

Step 4: Configure LACP Priorities (Optional)

For LACP mode, set system priority and interface priorities to determine which links are active and which serve as backups. Higher priority interfaces are selected as active.

Step 5: Assign VLANs to the Eth-Trunk

Add the Eth-Trunk interface to the required VLANs to allow traffic to pass through.

Step 6: Verify Configuration

Check the status of the Eth-Trunk and member interfaces to ensure proper aggregation and load balancing.

Best Practices

• Ensure all member interfaces have identical speed, duplex, and flow control settings.
• Avoid adding interfaces that are already part of other VLANs without removing them first.
• Use LACP mode when connecting to devices that support it for automatic failover and load balancing.
• Configure backup links to maintain redundancy in case of link failure . By following these steps, you can successfully configure an aggregation port on a Huawei switch, improving bandwidth, reliability, and load balancing between devices.
