Default
The default setting is auto, and the spanning tree device automatically detects whether a port
connects to a point-to-point link.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
auto: Specifies automatic detection of the link type.
force-false: Specifies the non-point-to-point link type.
force-true: Specifies the point-to-point link type.
Usage guidelines
When connecting to a non-point-to-point link, a port is incapable of rapid state transition.
You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that
operates in full duplex mode. As a best practice, use the default setting, which lets the device
automatically detect the port link type.
The stp point-to-point force-false or stp point-to-point force-true command configured on a port
in MSTP mode takes effect on all MSTIs or VLANs.
If the physical link to which the port connects is not a point-to-point link but you set it to be one, the
configuration might cause a temporary loop.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that
interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after
the port leaves the aggregation group.
Examples
# Configure the link that connects GigabitEthernet 1/0/3 as a point-to-point link.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/3
[Sysname-GigabitEthernet1/0/3] stp point-to-point force-true
Related commands

stp port priority
Use stp port priority to set the priority of a port. The port priority affects the role of a port in a
spanning tree.
Use undo stp port priority to restore the default.
Syntax
stp [ instance instance-list | vlan vlan-id-list ] port priority priority
undo stp [ instance instance-list | vlan vlan-id-list ] port priority
