instance-id: MST instance ID, in the range of 0 to 15.

vlan-list: VLAN list. You can specify multiple VLANs or VLAN ranges by providing 
this argument in the form of vlan-list = { vlan-id [ to vlan-id ] }&<1-10>, where, 
vlan-id is in the range of 1 to 4094, and &<1-10> means that you can specify up 
to 10 VLANs or VLAN ranges for this argument.

Use the instance command to map the specified VLAN(s) to the specified MST 
instance.

Use the undo instance command to remove the specified VLAN(s) from the 
specified MST instance and map the removed VLAN(s) to the CIST (MST instance 
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 MST instance will be remapped to the CIST.

■

You cannot map the same VLAN to different MST instances. If you map a VLAN 
that has been mapped to an instance to a new instance, the old mapping will 
be automatically removed.
