Automatic Discovery of an ONT

The MA5800 X15 system adds EG8141A5 using either of the following methods:

1.Adding Huawei EG8141A5 offline: Before installing Huawei EG8141A5, manually add Huawei EG8141A5 to the Huawei MA5800 X15 and configure Huawei EG8141A5. After Huawei EG8141A5 goes online, the Huawei MA5800 X15 authenticates the Huawei EG8141A5 and issues configurations to Huawei EG8141A5.

2.Adding Huawei EG8141A5 online: After Huawei EG8141A5 is installed, the Huawei MA5800 X15 discovers the online Huawei EG8141A5 and adds and configures it.

The automatic discovery of Huawei EG8141A5 applies when Huawei EG8141A5 is added online. In this scenario, the installation time of Huawei EG8141A5 is uncertain because the Huawei MA5800 X15 periodically searches for online Huawei EG8141A5.

3.The automatic discovery of Huawei EG8141A5 connecting to 1 Huawei MA5800 X15 PON ports is disabled by default.

4.Run the port ont-auto-find command to enable the automatic discovery of Huawei EG8141A5.

5.Run the display ont autofind command to query the automatic discovery of Huawei EG8141A5.
