Configure the portpriority.• In STP/RSTP mode:stp port priority priority• In PVST mode:stp vlan vlan-list port priority priority• In MSTP mode:stp [ instance instance-id ] port priority priorityUse one of thecommands.The default setting is128.Configuring the port link typeA point-to-point link directly connects two devices. If two root ports or designated ports are connectedover a point-to-point link, they can rapidly transit to the forwarding state after a proposal-agreementhandshake process.Configuration restrictions and guidelines• You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port thatoperates in full duplex mode. H3C recommends you to use the default setting and let the device toautomatically detect the port link type.• The stp point-to-point force-false or stp point-to-point force-true command configured on a port inMSTP 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, theconfiguration might bring a temporary loop.Configuration procedureTo configure the link type of a port or a group of ports:Step Command Remarks1.
