Transition Networks STP MSTI Port Configuration SISPM1040-3xxx-L Web User Guide Figure 11-4: STP MSTI Port Configuration Parameter descriptions: Port : The switch port number of the logical STP port. STP Enabled : Controls whether STP is enabled on this switch port. This field will be read only if Voice VLAN feature is enabled. The Voice VLAN port mode will be read only if this field be Enabled. Path Cost : Controls the path cost incurred by the port. The Auto setting will set the path cost as appropriate by the physical link speed, using the 802.1D recommended values. Using the Specific setting, a user-defined value can be entered. The path cost is used when establishing the active topology of the network. Lower path cost ports are chosen as forwarding ports in favor of higher path cost ports. Valid values are 1 to 200000000. Priority : This can be used to control priority of ports having identical port cost. (See above). AdminEdge : Controls whether the operEdge flag should start as set or cleared. (The initial operEdge state when a port is initialized). AutoEdge : Controls whether the bridge should enable automatic edge detection on the bridge port. This allows operEdge to be derived from whether BPDU's are received on the port or not. 33763 Rev. G https://www.transition.com Page 185 of 496
