Hello, friend!
The DG8245V-10 is a customized device model for the ISP.
To address your question, log in to the WebUI of the device using the device administrator account, download the fault information file of the device, and view the CRC error statistics of the device.
In the navigation tree on the left, choose Advanced > Maintenance > Debug Collection. In the pane on the right, click Start to collect DSL home gateway fault information.
(Because the device version is a custom version, I cannot ensure that the information you need is in the fault collection file.)
Thanks!
