Description
Maps VLANs to an MST instance as follows:
• For instance_id, the range is from 1 to 4094.
Instance 0 is reserved for the IST for each MST
region.
• For vlan-range, the range is from 1 to 4094.
When you map VLANs to an MSTI, the mapping is
incremental, and the VLANs specified in the command
are added to or removed from the VLANs that were
previously mapped.
Deletes the specified instance and returns the VLANs
to the default MSTI, which is the CIST.
