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 transit to the forwarding state after a proposal-agreement
handshake process.
Configuration restrictions and guidelines
•
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. 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 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 bring a temporary loop.
Configuration procedure
To configure the link type of a port or a group of ports:
Step Command
Remarks

link type.
Configuring the mode a port uses to
recognize/send MSTP packets
A port can receive/send MSTP packets in the following formats:
