Parameters
instance-id: Specifies an MSTI ID. The minimum value is 0, representing the CIST, and the maximum
value is 4094.
vlan vlan-id-list: Specifies a VLAN list in the format of vlan-id-list = { vlan-id [ to vlan-id ] }&<1-10>. The
vlan-id argument represents the VLAN ID and its value range is 1 to 4094. &<1-10> indicates that you
can specify up to 10 VLAN IDs or VLAN ID ranges.
Usage guidelines
If you specify no VLAN in the undo instance command, all VLANs mapped to the specified MSTI are
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 is automatically removed.
You can configure VLAN-to-instance mapping for up to 16 MSTIs.
After configuring this command, run the active region-configuration command to activate the
VLAN-to-instance mapping.
When Digest Snooping is enabled globally, use caution when you modify the VLAN-to-instance
mappings or execute the undo stp region-configuration command to restore the default MST region
configuration. These operations might cause loops or traffic disruption because the VLAN-to-instance
mappings are inconsistent with those on the neighboring devices.
Examples
# Map VLAN 2 to MSTI 1.
<Sysname> system-view
[Sysname] stp region-configuration
[Sysname-mst-region] instance 1 vlan 2
