Configuring Edge Ports and BPDU Filter Ports
Context
A port that is located at the edge of a network and directly connected to a terminal device is an edge port.
Edge ports can still send BPDUs, but if the BPDUs are sent to another network then network flapping may occur on that network. To prevent this problem, configure the BPDU filter function on edge ports so that the edge ports do not process or send BPDUs.
If all the ports are configured as both edge ports and BPDU filter ports in the system view, none of ports on the local device can send BPDUs or negotiate STP states with directly connected ports on peer devices. Additionally, all ports are in Forwarding state. This may cause loops on the network, leading to broadcast storms. Exercise caution when deciding to perform this configuration.
After a specified port is configured as both an edge port and a BPDU filter port in the interface view, the port does not process or send BPDUs and cannot negotiate the STP state with the directly connected port on the peer device. Exercise caution when deciding to perform this configuration.
