1-28To do… Use the command… RemarksSpecify whether the linkconnected to a port is apoint-to-point linkstp point-to-point { force-true| force-false | auto }RequiredThe auto keyword is adoptedby default.z Among aggregated ports, you can only configure the links of master ports as point-to-point links.z If an auto-negotiating port operates in full duplex mode after negotiation, you can configure the linkof the port as a point-to-point link.After you configure the link of a port as a point-to-point link, the configuration applies to all the spanningtree instances the port belongs to. If the actual physical link of a port is not a point-to-point link and youforcibly configure the link as a point-to-point link, loops may occur temporarily.Configuration example# Configure the link connected to GigabitEthernet 1/0/1 as a point-to-point link.1) Perform this configuration in system view system-view[device] stp interface GigabitEthernet1/0/1 point-to-point force-true2) Perform this configuration in Ethernet port view system-view[device] interface GigabitEthernet1/0/1[device-GigabitEthernet1/0/1] stp point-to-point force-trueEnabling MSTPConfiguration procedureFollow these steps to enable MSTP in system view:To do… Use the command… RemarksEnter system view system-view —Enable MSTP stp enable RequiredMSTP is disabled by default.Disable MSTP onspecified portsstp interface interface-listdisableOptionalBy default, MSTP is enabled on all ports afteryou enable MSTP in system view.To enable a device to operate more flexibly, youcan disable MSTP on specific ports. AsMSTP-disabled ports do not participate inspanning tree calculation, this operation savesCPU resources of the device.Follow these steps to enable MSTP in Ethernet port view:
