View

Default level
2: System level
Parameters
instance-id: Specifies an MSTI ID, ranging from 0 to 16, where 0 represents the CIST.
vlan vlan-list: Specifies a VLAN list in the format of vlan-list = { vlan-id [ to vlan-id2 }&<1-10>, in which
vlan-id represents the VLAN ID and ranges from 1 to 4094. &<1-10> indicates you can specify up to 10
VLAN IDs or VLAN ID ranges.
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.
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.
