Hi friend.
For the preceding two problems, you can configure traffic alarms in the traffic alarm template of NCE. For details, see the following sections:
Navigation Path on the Global Side
Open the Network Management app and choose Service > Access Service > Access Profile Management from the main menu.
In the dialog box that is displayed, choose PON Profile > Traffic Alarm Profile from the navigation tree.
Navigation Path on the NE Side
Open the Network Management app and choose Topology > View > Physical Topology from the main menu. On the Physical Topology tab page, press Ctrl+F. Enter an NE name or IP address. In the search result list that is displayed, click the name of the target NE. In the Operations area, click NE Explorer.
Choose NE Profile Management > Traffic Alarm Profile from the navigation tree.

As for the last question, there is no configuration to implement.
Thanks.
