@sim_157 Hi,
Firstly, you are kindly advised to adjust the links bound to the eth-trunk to 4 or other number exponential multiple of 2.
If the traffic load balance not evenly after the adjust the confiugration, you’d better to capture packets on device and inspect the characteristic of the packets.
In addition, it is the input traffic which load balance not evenly, you should check the upstream device, and adjust the load balance algorythm.
