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.
