Hello, friend!
You can run the clear statistics ont-line-quality command to clear the line quality statistics of online ONTs. To collect the line quality statistics of the ONT within a specified period, you must clear the original statistics and re-collect the statistics before the statistics start. The items to be cleared are those queried by running the display statistics ont-line-quality command.
To clear the line quality statistics of all ONTs connected to GPON port 0/1/0, do as follows:
huawei(config-if-gpon-0/1)#clear statistics ont-line-quality 0
{<cr>|ontid<U><0,127>}:
Command:
clear statistics ont-line-quality 0
Thanks!
