I. Configuration procedure
Follow these steps to configure whether a port or a group of ports connect to
point-to-point links:
To do... Use the command... Remarks

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 whether the
port(s) connect to
point-to-point links
stp point-to-point { auto
| force-false | force-true }
Optional
The default setting is
auto; namely the device
automatically detects
whether an Ethernet port
connects to a
point-to-point link.
 Note:
z In the case of link aggregation, every port in the aggregation group can be
configured to connect to a point-to-point link. If a port works in auto-negotiation
mode and the negotiation result is full duplex, this port can be configured as
connecting to a point-to-point link.
z If a port is configured as connecting to a point-to-point link, the setting takes effect
for the port in all MST instances. If the physical link to which the port connects is not
a point-to-point link and you force it to be a point-to-point link by configuration, the
configuration may incur a temporary loop.
II. Configuration example
# Configure port GigabitEthernet 2/0/1 as connecting to a point-to-point link.
<Sysname> system-view
[Sysname] interface GigabitEthernet 2/0/1
