H3C s3100 series Command Manual page 270

force-false: Specifies that the link connected to the current Ethernet port is not a point-to-point link.
auto: Specifies to automatically determine whether or not the link connected to the current Ethernet port
is a point-to-point link.
interface-list: Ethernet port list. You can specify multiple Ethernet ports by providing this argument in the
form of interface-list = { interface-type interface-number [ to interface-type interface-number ] } &<1-10>,
where &<1-10> means that you can provide up to 10 port indexes/port index ranges for this argument.
Description
Use the stp point-to-point command to specify whether the link connected to the current Ethernet
port is a point-to-point link. Use the undo stp point-to-point command to restore the link
connected to the current Ethernet port to its default link type, which is automatically determined by
MSTP.
Use the stp interface point-to-point command to specify whether the links connected to the
specified Ethernet ports are point-to-point links in system view. Use the undo stp interface
point-to-point command to restore the links connected to the specified ports to their default link
types, which are automatically determined by MSTP.
The default setting is auto; namely the MSTP-enabled device automatically detects whether a port
connects to a point-to-point link.
If no keyword is specified in the stp point-to-point command, the auto keyword is used by default, and
so MSTP automatically determines the type of the link connected to the current port.
The rapid transition feature is not applicable to ports on non-point-to-point links.
Note that:
If the current Ethernet port operates in full duplex mode, the links connected to the port is a
point-to-point link. In this case, the default setting (where MSTP determines the link type
automatically) is recommended.
If the current Ethernet port belongs to an aggregation group and you configure the link connected
to the port as a point-to-point link, the configuration will be synchronized to the rest ports in the
aggregation group.
If a port is configured to connect to a point-to-point link (or non-point-to-point link), the port adopts
the same configuration in all spanning tree instances.
If a port connects to a non-point-to-point link, but the port is configured to connect to a point-to-point
link by mistake, loops may temporarily occur.
