The eth-trunk interface turns down, and we found some corresponding logs from the switch, could you guys help to explain these logs, and what should we do in the next action.

Thanks

Hello,
From the logs, the eth-trunk interface turns down because of the changed LACP PDU received on the local device, please check the eth-trunk configuration on the remote device to find out if the configuration had been modified. If so, please find out the different configuration and do the same configuration on local device.
