Description
Use the instance command to map a list of VLANs to the specified MSTI.
Use the undo instance command to remap the specified VLAN or all VLANs to the CIST (MSTI 0).
By default, all VLANs are mapped to the CIST.
If you specify no VLAN in the undo instance command, all VLANs mapped to the specified MSTI will be
remapped to the CIST.
You cannot map the same VLAN to different MSTIs. If you map a VLAN that has been mapped to an
MSTI to a new MSTI, the old mapping will be automatically removed.
In PVST mode, you can map multiple VLANs to the CIST, and only one VLAN to each remaining MSTI.
After configuring this command, run the active region-configuration command to activate the VLAN-to-
instance mapping.
Related commands: display stp region-configuration, check region-configuration, and active region-
configuration.
