MA5200G service port collects software monitoring traffic, but cannot check any data.
In order to make the protocol status of main interface as up, only configure undo shutdown at main interface. Configure bas interface and user access-type is configured as layer2-subscriber. Then the protocol status of main interface is UP and collecting information with trafficview can be done.
There is not any configuration of main interface at MA5200G. Enable relevant bas data at sub-interface, and the physical status of main port is up and the protocol status is down. However, trafficview requires that physical status and the protocol status should be UP. So it fails.
