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.
force-true: Specifies that the links connected to the specified Ethernet ports are
point-to-point links.
force-false: Specifies that the links connected to the specified Ethernet ports are not
point-to-point links.
auto: Specifies to automatically determine whether or not the links connected to the
specified Ethernet ports are point-to-point links.
Description
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.
If no keyword is specified in the stp interface point-to-point command, the auto
keyword is used by default, and so MSTP automatically determines the types of the
links connected to the specified ports.
The rapid transition feature is not applicable to ports on non-point-to-point links.
If an Ethernet port is the master port of an aggregated port or operates in full-duplex
mode, the link connected to the port is a point-to-point link.
You are recommended to let MSTP automatically determine the link types.
These two commands only apply to CIST and MSTIs. If you configure the link to which
a port is connected to be a point-to-point link (or a non-point-to-point link), the
configuration applies to all spanning tree instances (that is, the port is configured to
connect to a point-to-point link (or a non-point-to-point link) in all spanning tree
instances). If the actual physical link is not a point-to-point link and you configure the
link to which the port is connected to be a point-to-point link, loops may temporarily
occur.
Related command: stp point-to-point.
