Spanning Tree (STP) Commands | 323Port Identifier The port identifier for this port within the CST.Port Priority The priority of the port within the CST.Port Forwarding State The forwarding state of the port within the CST.Port Role The role of the specified interface within the CST.Port Path Cost The configured path cost for the specified interface.Designated Root Identifier of the designated root for this port within the CST.Designated Port Cost Path Cost offered to the LAN by the Designated Port.Designated Bridge The bridge containing the designated portDesignated Port Identifier Port on the Designated Bridge that offers the lowest costto the LANTopology Change Acknowledgement Value of flag in next Configuration Bridge Pro-tocol Data Unit (BPDU) transmission indicating if a topol-ogy change is in progress for this port.Hello Time The hello time in use for this port.Edge Port The configured value indicating if this port is an edge port.Edge Port Status The derived value of the edge port status. True if operatingas an edge port; false otherwise.Point To Point MAC Status Derived value indicating if this port is part of a point topoint link.CST Regional Root The regional root identifier in use for this port.CST Port Cost The configured path cost for this port.spanning-tree mstiThis command sets the path cost or port priority for this port within the multiple spanning tree instance(MSTi) or in the common and internal spanning tree.Syntax spanning-tree msti {0 {cost 1-200000000 | external-cost 1-200000000 | priority 0-240} |1-63 {cost 1-200000000 | priority 0-240}}no spanning-tree msti sets the value of the selected option to its default.If the msti parameter corresponds to an existing multiple spanning tree instance, then theconfigurations are done for that MSTi. If, however, 0 (defined as the default CIST ID) is passed as themsti, then the configurations are performed for the common and internal spanning tree instance.If the cost token is specified, this command sets the path cost for this port within a multiple spanningtree instance or the common and internal spanning tree instance, depending on the msti parameter. Thepath cost is specified as a number in the range of 1 to 200000000.Parameters 0 or 1-63 Enter an integer between 0 and 63 to specify an instance.{cost 1-200000000 |external-cost 1-200000000 |priority 0-240}Specify a value for either cost (port cost), external-cost(external port cost for port used by a MST), or priority (portpriority value, in increments of 16 (default = 128). See below.Note that the external-cost parameter is only an option for the 0keyword.
