Configure the port priority (in STP/RSTP
mode)

Configure the port priority (in MSTP mode)

stp [ instance instance-id ] port
priority priority

Required
Use any command.
128 for all ports by
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.
