Operation Manual – MSTPH3C S5100-SI/EI Series Ethernet Switches Chapter 1 MSTP Configuration1-34Note:z If you configure the link connected to a port in an aggregation group as apoint-to-point link, the configuration will be synchronized to the rest ports in thesame aggregation group.z If an auto-negotiating port operates in full duplex mode after negotiation, you canconfigure the link of 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 toall the MSTIs the port belongs to. If the actual physical link of a port is not apoint-to-point link and you forcibly configure the link as a point-to-point link, loops mayoccur temporarily.III. 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[Sysname] stp interface GigabitEthernet 1/0/1 point-to-point force-true2) Perform this configuration in Ethernet port view system-view[Sysname] interface GigabitEthernet 1/0/1[Sysname-GigabitEthernet1/0/1] stp point-to-point force-true1.3.14 Enabling MSTPI. Configuration procedureFollow these steps to enable MSTP in system view:To do... Use thecommand... RemarksEnter system view system-view —Enable MSTP stp enable RequiredMSTP is disabled by default.Disable MSTP onspecified portsstp interfaceinterface-listdisableOptionalBy default, MSTP is enabled on all portsafter you enable MSTP in system view.To enable a switch to operate more flexibly,you can disable MSTP on specific ports. AsMSTP-disabled ports do not participate inspanning tree calculation, this operationsaves CPU resources of the switch.
