TL-SL5428E 24-port 10/100Mbps + 4-port Gigabit L2 Managed Switch CLI Guide determining if the port connected to this port will be chosen as the root port. In the same condition, the port with the highest priority will be chosen as the root port. The lower value has the higher priority. expath-consum -- ExtPath Cost, which is used to choose the path and calculate the path costs of ports in different MST regions. It is an important criterion on determining the root port. The lower value has the higher priority. By default, it is automatic. inpaht-consum -- IntPath Cost, which is used to choose the path and calculate the path costs of ports in an MST region. It is an important criterion on determining the root port. The lower value has the higher priority. By default, it is automatic. edge -- Enable/ Disable Edge Port. By default, it is disabled. The edge port can transit its state from blocking to forwarding rapidly without waiting for forward delay. ptop -- The P2P link status, with auto, open and close options. By default, the option is auto. If the two ports in the P2P link are root port or designated port, they can transit their states to forwarding rapidly to reduce the unnecessary forward delay. Command Mode Interface Configuration Mode（interface ethernet / interface range ethernet） Example Enable the STP function of port 1, and configure the Port Priority as 64, ExtPath Cost as 100, IntPath Cost as 100, and then enable Edge Port: TP-LINK(config)# interface Ethernet 1 TP-LINK(config-if)# spanning-tree common-config enable enable pri 64 expath 100 inpath 100 edge enable spanning-tree region Description The spanning-tree region command is used to configure the region of MSTP. A switched network can be divided into many MST regions (Multiple Spanning Tree Regions). An MST region comprises multiple switches which have the same region configuration (including region name and region revision configuration) and the same VLAN-to-spanning-tree mapping configuration. 151
