Usage guidelines
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.
Examples
# Map VLAN 2 to MSTI 1.
<Sysname> system-view
[Sysname] stp region-configuration
[Sysname-mst-region] instance 1 vlan 2
