To return to the privileged EXEC mode, enter end or press Ctrl+C.
To return to the global configuration mode, enter exit.
After entering the MST configuration mode, you can use the following commands to
configure parameters:
instance instance-id vlan vlan-range: Adds the VLANs to the MST instance. The range of
instance-id is 0 to 64 and the range of VLAN is 1 to 4095. The vlan-range can be a set of
some inconsecutive VLANs separated with comma or some consecutive VLANs in the form
of start VLAN number–end VLAN number. For example, instance 10 vlan 2,3,6-9 means
that VLANs 2, 3, 6, 7, 8, 9 are added to instance 10. By default, all VLANs are in Instance 0.
To remove a VLAN from an instance, use the no option of the command: no instance
instance-id [vlan vlan-range]. (In this case, the range of instance is 1 to 64).
You are advised to control the number of instances created in a pile.
name name: Specify the MST name, a string of up to 32 characters. You can use the no
name command to restore the default setting.
revision version: Set the MST version which ranges from 0 to 65535. You can use the no
name command to restore the default setting.
show spanning-tree mst configuration: Shows the information of the current MST region.
This example shows how to enter the MST configuration mode, and map VLANs 3, 5 to 10 to
MST instance 1:
Ruijie(config)# spanning-tree mst configuration
Ruijie(config-mst)# instance 1 vlan 3, 5-10
Ruijie(config-mst)# name region 1
Ruijie(config-mst)# revision 1
Ruijie(config-mst)# show spanning-tree mst configuration
MST configuration
Name [region1]
Revision 1
Instance Vlans Mapped
---------- ---------------------
0 1-2,4,11-4094
1 3,5-10
-----------------------------------
Ruijie(config-mst)# exit
Ruijie(config)#
To remove VLAN 3 from instance 1, execute this command after entering the MST
configuration mode:
Ruijie(config-mst)# no instance 1 vlan 3
Use the following demand to delete instance 1:
Ruijie(config-mst)# no instance 1
You can verify the above with the show command of the MST configuration commands.
