Spanning Tree (STP) Commands | 325The instance mstid is a number in the range 0-63 that corresponds to the desired existing multiplespanning tree instance.0–61440 is the priority value, representing a range of 0 to 61440 in increments of 4096.If 0 (defined as the default CIST ID) is passed as the mstid, this command sets the bridge priorityparameter to a new value for the common and internal spanning tree. The bridge priority value is anumber within a range of 0 to 61440. The twelve least significant bits will be masked, in accordancewith the 802.1s specification. This causes the priority to be rounded down to the next lower validpriority.The no version of this command sets the bridge priority for a specific multiple spanning tree instanceto the default value, in other words, 32768.Default 32768Mode Global Config; Interface Range, which is indicated by the (conf-if-range-interface)# prompt, such as(conf-if-range-vlan 10-20)#.CommandHistoryspanning-tree msti vlanThis command adds an association between a multiple spanning tree instance and a VLAN. The VLANwill no longer be associated with the common and internal spanning tree.Syntax [no] spanning-tree msti vlan msti vlanidThe mstid is a number that corresponds to the desired existing multiple spanning tree instance. Thevlanid corresponds to an existing VLAN ID.The no version of this command removes an association between a multiple spanning treeinstance and a VLAN. The VLAN will again be associated with the common and internalspanning tree. The instance mstid is a number that corresponds to the desired existing multiplespanning tree instance. The vlanid corresponds to an existing VLAN ID.Mode Global ConfigCommandHistoryVersion 2.5.1 Modified: Revised syntax from spanning-tree mst priority mstid; changed the range.Version 2.3 Added Interface Range mode.RelatedCommandsinterface Identifies an interface and enters the Interface Config mode.interface range Defines an interface range and accesses the Interface Range modeVersion 2.5.1 Modified: Revised syntax from spanning-tree mst vlan mstid vlanid
