I. Configuration procedure
Follow these steps to specify a port or a group of ports as edge port(s):

Required
Use either command.
Configurations made in
Ethernet interface view
will take effect on the
current port only;
configurations made in
port group view will take
effect on all ports in the
port group.
Configure the port(s) as
edge port(s)
stp edged-port enable
Required
All Ethernet ports are
non-edge ports by default.
 Note:
z With BPDU guard disabled, when a port set as an edge port receives a BPDU from
another port, it will become a non-edge port again. In this case, you must reset the
port before you can configure it to be an edge port again.
z If a port directly connects to a user terminal, configure it to be an edge port and
enable BPDU guard for it. This enables the port to transition to the forwarding state
while ensuring network security.
II. Configuration example
# Configure GigabitEthernet 2/0/1 to be an edge port.
<Sysname> system-view
[Sysname] interface GigabitEthernet 2/0/1
[Sysname-GigabitEthernet2/0/1] stp edged-port enable
1.3.11 Configuring Whether Ports Connect to Point-to-Point Links
A point-to-point link is a link directly connecting with two devices. If the two ports across
a point-to-point link are root ports or designated ports, the ports can rapidly transition to
the forwarding state after a proposal-agreement handshake process.
