6.6.3.8 Configuring Edge Ports and BPDU Filter Ports

Context
As defined in RSTP, a port that is located at the edge of a network and directly connected to a
terminal device is an edge port.
An edge port does not process configuration BPDUs or participate in RSTP calculation. It can
transit from the Disable to Forwarding state without any delay.
Edge ports can still send BPDUs. If the BPDUs are sent to another network, this network may
encounter network flapping. To prevent this problem, configure the BPDU filter function on
edge ports so that the edge ports do not process or send BPDUs.
