Hi, there.
How to investigate discard in upstream GPON port?
1. Generally, you can use the following commands to get more information about the statistics about service-port:
huawei(config)#start statistics service-port [index] //for each service-port on the port
//reproduce the issue (find some discard on the port)
huawei(config)#display statistics service-port [index ] //try to find if any discard statistics on the service-port
huawei(config)#stop statistics service-port [index]
2. The service-port capture can be used to capture packets on each service-port on the port:
//start the capture
MA5600T(diagnose)%%file-server auto-backup board-info primary [server-ip] tftp //you can choose ftp
MA5600T(diagnose)%ture service-port [srvid] capture-count 1000000 capture-time 2000
//reproduce the issue
// undo the capture
MA5600T(diagnose)%%undo capture service-port
MA5680T(diagnose)%%undo file-server auto-backup board-info primary
Thanks.
