Hello everyone,

Today I will share with you how to solve the 5700 Eth-trunk load imbalance problem.

Please give me some advice, thank you!

Hi Hobbit,
1. Check whether the interface bandwidths at both ends match.
2. Check whether the eth-trunk modes at both ends match. It is recommended that the aggregation mode be dynamic lacp.
3. As shown in the information you post, the Eth-Trunk interface uses the hash algorithm based on the source IP address or the destination IP address by default. In the IP network, the algorithm ensures even load balancing because the IP address changes randomly. However, on a Layer 2 network, a large number of MAC addresses change and IP addresses are fixed. As a result, load balancing is uneven.
If the two sides of the algorithm is not consistent will also lead to uneven load.
You can run the load-balance command to modify the hash algorithm. please refer to

4. For broadcast and multicast, you can run the unknown-unicast load-balance {dmac | smac | smacxordmac | enhanced} command in the system view to configure the load balancing mode.

Are you passing mpls traffic on this port?
