Video: Disabling BPDU (Bridge Protocol Data Unit) Packets on a PM8000/ION7400 Meter

A PM8000 meter may disable an ethernet port on a network port upon connection due to a BPDU guard on a network. PM8000 meters send out BPDU packets while RSTP (Rapid Spanning Tree Protocol) is enabled.

The video below shows how to use ION Setup to disabling BPDU (Bridge Protocol Data Unit) Packets on a PM8000/ION7400 Meter.

This will disable BPDU packets from being sent out by the PM8000/ION7400 meter.

NOTE: This does not impede the switch functionality of the PM8000s ethernet ports.
