You can enable a port to turn to the forwarding state rapidly by setting it to an edge port. And you are
recommended to configure the Ethernet ports directly connected to user terminals as edge ports to
enable them to turn to the forwarding state rapidly.
Normally, configuration BPDUs cannot reach an edge port because the port is not connected to another
switch. But when the BPDU guard function is disabled on an edge port, configuration BPDUs sent
deliberately by a malicious user may reach the port. If an edge port receives a BPDU, it turns to a
non-edge port.
Loop guard, root guard, and edge port settings are mutually exclusive. With one of these functions
enabled on a port, any of the other two functions cannot take effect even if you have configured it on the
port.
