bcm.user is handling the internal switch

If you don't use the internal switch, start by disabling it, or disable device-identification if you have a lot of devices in the LAN (thousands). Not excluding a bug in the firmware, but that should be checked through a support case.

Hi MickeulK,

what is your topology? Is the same topology no issue in V7.0.3? you can create Add Dashboard Widget -- Interface Bandwidth to monitor traffic on an interface?
