Operation Manual – MSTPH3C S7500 Series Ethernet Switches Chapter 1 MSTP Configuration1-22To do ... Use the command ... RemarksSpecify whether ornot the linkconnected to theport is apoint-to-point linkstp point-to-point{ force-true | force-false |auto }RequiredThe auto keyword is adoptedby default.The force-true keywordspecifies that the linkconnected to the port is apoint-to-point link.The force-false keywordspecifies that the linkconnected to the port is not apoint-to-point link.The auto keyword specifies toautomatically determinewhether or not the linkconnected to the port is apoint-to-point link.Note:Among aggregated ports, you can configure only the links of master ports aspoint-to-point links. If an auto-negotiating port operates in full duplex mode afternegotiation, you can configure 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 MSTIs. If the actual physical link of a port is not a point-to-point link and you forciblyconfigure the link as a point-to-point link, temporary loops may be incurred.III.
