default.
NOTE:
When the priority of a port changes, MSTP re-calculates the role of the port and initiates a state transition.
Configuring the port link type
A point-to-point link directly connects two devices. If two root ports or designated ports are connected
over a point-to-point link, they can rapidly transition to the forwarding state after a proposal-agreement
handshake process.
Follow these steps to configure the link type of a port or a group of ports:

Configure the port link type
stp point-to-point { auto
| force-false |
force-true }
Required
By default, the link type is auto
where the port automatically detects
the link type.
NOTE:
•
You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that works
in full duplex mode. H3C recommends you to use the default setting and let the device to 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 or PVST mode is effective for 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 bring a temporary loop.
