Use the display eth-trunk command to view aggregation ports and their status on Huawei switches.

Checking Link Aggregation (Eth-Trunk) Configuration

On Huawei S series switches, link aggregation groups are called Eth-Trunks. To view the configuration and member ports:

• Basic command:

  display eth-trunk [trunk-id] This shows the Eth-Trunk ID, member interfaces, and their operational status .

• Detailed view:

  display eth-trunk [trunk-id] verbose This provides additional information such as load balancing mode, link status, and traffic statistics for each member port .

• Check a specific interface:

  display eth-trunk [trunk-id] interface [interface-type interface-number] This shows whether a particular port is part of the aggregation group and its current state .

Understanding the Output

The output typically includes:

• Eth-Trunk ID: Identifier for the aggregation group.
• Member interfaces: List of physical ports included in the Eth-Trunk.
• Status: Whether each port is up or down.
• Load balancing mode: How traffic is distributed across member ports (e.g., src-dst-mac, src-dst-ip).
• Traffic statistics: Packets sent/received per member port.

Additional Notes

• Huawei switches support manual (static) aggregation by default, so you may not need to configure the aggregation mode unless using LACP .
• Ensure that all member ports have consistent speed, duplex, VLAN, and STP settings to avoid errors .
• For troubleshooting, you can also check interface-specific statistics to verify if traffic is being properly balanced across the aggregation group . By using these commands, you can effectively monitor and verify the configuration and operational status of aggregation ports on your Huawei switch.
