Multiple Spanning Tree Protocol (MSTP)
Commands
24-1
instance
This command is used to map a VLAN or a set of VLANs to an MST instance. Use the
no
instance without
VLANs specified to remove instances. Use the
no
instance with VLAN specified to return the VLANs to the
default instance (CIST).

Parameters
INSTANCE-ID
Specifies the MSTP instance identifier to which the specified
VLANs are mapped. This value must be between 1 and 4094.
vlans
VLANDID
Specifies the VLANs to be mapped to or removed from the specified
instance. This value must be between 1 and 4094.
,
(Optional) Specifies a series of VLAN, or separate a range of
interfaces from a previous range. No space is allowed before and
after the comma.
-
(Optional) Specifies a range of VLAN. No space is allowed before
and after the hyphen
Default
None.
Command Mode
MST Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
Any unmapped VLAN is mapped to the CIST instance. When mapping the VLANs to an instance, if the
instance doesn’t exist, this instance will be created automatically. If all VLANs of an instance are removed, this
instance will be destroyed automatically. In another way, users can remove the instance manually by using the
no instance
command without VLANs specified.
Example
This example shows how to map a range of VLANs to instance 2.
