Cisco Systems N3KC3064TFAL3, N3KC3048TP1GE manual Command or Action, Purpose, Step

Configuring Multiple Spanning Tree

Specifying the Configuration on an MST Region

	Command or Action	Purpose
		When you map VLANs to an MST instance, the mapping is
		incremental, and the VLANs specified in the command are added
		to or removed from the VLANs that were previously mapped.
		To specify a VLAN range, enter a hyphen; for example, enter
		the instance 1 vlan 1-63command to map VLANs 1 through
		63 to MST instance 1.
		To specify a VLAN series, enter a comma; for example, enter
		the instance 1 vlan 10, 20, 30 command to map VLANs 10,
		20, and 30 to MST instance 1.
Step 4	switch(config-mst)# name	Specifies the instance name. The name string has a maximum
	name	length of 32 characters and is case sensitive.
Step 5	switch(config-mst)# revision	Specifies the configuration revision number. The range is from
	version	0 to 65535.

To return to defaults, do the following:

•To return to the default MST region configuration settings, enter the no spanning-tree mst configuration configuration command.

•To return to the default VLAN-to-instance map, enter the no instance instance-idvlan vlan-rangeMST configuration command.

•To return to the default name, enter the no name MST configuration command.

•To return to the default revision number, enter the no revision MST configuration command.

•To reenable Rapid PVST+, enter the no spanning-tree mode or the spanning-tree mode rapid-pvst global configuration command.

This example shows how to enter MST configuration mode, map VLANs 10 to 20 to MST instance 1, name the region region1, set the configuration revision to 1, display the pending configuration, apply the changes, and return to global configuration mode:

switch(config)# spanning-tree mst configuration switch(config-mst)#instance 1 vlan 10-20 switch(config-mst)#name region1 switch(config-mst)#revision 1 switch(config-mst)#show pending

Pending MST configuration
