332 CHAPTER 10: USING RSTP COMMANDS View Ethernet Port View Parameter force-true: Indicates that the link to the current Ethernet port is a point-to-point link. force-false: Indicates that the link to the current Ethernet port is not a point-to-point link. auto: Specifies to automatically check if the link to the Ethernet port is a point-to-point link or not. Description Use the stp point-to-point command to configure the state of the link to the current Ethernet port as a point-to-point link or not a point-to-point link. Use the undo stp point-to-point command to restore the default status of the link, that is, RSTP is responsible for checking whether the link to the current Ethernet port is a point-to-point link or not. By default, the value is auto. Example To indicate that the link to GigabitEthernet1/0/1 is a point-to-point link, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]interface GigabitEthernet1/0/1 [SW5500-GigabitEthernet1/0/1]stp point-to-point force-true stp port priority Syntax stp port priority port-priority undo stp port priority View Ethernet Port View Parameter port-priority: Specifies the priority of the port, ranging from 0 to 240. The values are not consecutive integers. Step length is 16. By default, the value is 128. Description Use the stp port priority command to configure the priority of the current Ethernet port. Use the undo stp port priority command to restore the default priority. The priority value shall be a multiple of 16, such as 0, 16, 32, 48 etc. The smaller value represents the higher priority. A port with higher priority (lower numerical value) is more likely to be a root port.
