Default Level
2: System level
Parameters
instance-id: MSTI ID. The minimum value is 0, representing the CIST, and the maximum value is 31.
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 the specified 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.
Notice that:
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, you need to 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.
