Hi,
If you disable STP function on an interface, the interface status does not change when a BPDU is received.
If you mean enable an interface to be an edge port, the edge port attribute is ineffective when receiving a BPDU.
Configuring a Port as an Edge Port | Configuring All Ports as Edge Ports | Configuring a Port as a BPDU Filter Port | Configuring All Ports as BPDU Filter Ports | Default Behavior | After a Packet Is Received | Packet Sending |
|---|
Y | N/A | N/A | N/A | After STP is enabled on a port, the port is an edge port. | The edge port attribute is ineffective. | Packets are sent. |
N/A | Y | N/A | N/A | After STP is enabled on a port, the port is an edge port. | The edge port attribute is ineffective. | Packets are sent. |
N/A | N/A | Y | N/A | After STP is enabled on a port, the port is a BPDU-filter port. | The packet is dropped. | No packet is sent. |
N/A | N/A | N/A | Y | BPDU-filter ports are disabled by default. | The packet is processed normally. | Packets are sent. |
Y | N/A | Y | N/A | After STP is enabled on a port, the port is an edge port. After STP is enabled on a port, the port is a BPDU-filter port. | The packet is dropped, and the edge port attribute still takes effect. | No packet is sent. |
Y | N/A | N/A | Y | After STP is enabled on a port, the port is an edge port. After STP is enabled on a port, the port is a BPDU-filter port by default. | Both the edge port and BPDU-filter port configuration become ineffective. | By default, no packet is sent. If the port receives a packet, it starts sending packets. |
N/A | Y | Y | N/A | After STP is enabled on a port, the port is an edge port. After STP is enabled on a port, the port is a BPDU-filter port by default. | The packet is dropped, and the edge port attribute still takes effect. | No packet is sent. |

N | N/A | N | N/A | The BPDU-filter port is forcibly disabled. | The packet is processed normally. | Packets are sent. |
