Chapter 1 MSTP Configuration Commands
Huawei Technologies Proprietary

Description
Use the
instance
command to map the specified VLAN list to the specified MSTI.
Use the
undo instance
command to cancel the specified VLAN list from the specified
MSTI, and the removed VLAN will then be mapped to the CIST (i.e., the Instance 0). If
no VLAN is specified in the
undo
command, all the VLANs associated with the
specified MSTI will be mapped to CIST.
By default, all the VLANs are mapped to CIST, i.e., the Instance 0.
MSTP describes the association between VLANs and MSTIs with the VLAN mapping
table. You can use this command to configure this table. Every VLAN can be mapped to
an MSTI as per your configuration.
You cannot map one VLAN to different instances, while you can map multiple VLANs to
one instance. When you remap the mapped VLAN to a different instance, the original
mapping relation is removed automatically. The mapping relationship of VLANs and
instances in the same MSTP domain must be correct. The data will be transmitted
according to the spanning tree topology structure of the instance the VLAN maps to.
