Syntax Description
Defaults This command has no default settings.

Command Modes Privileged.
Usage Guidelines All changes made to the region configuration (region information and VLAN mapping) are buffered.
Only one user can hold the buffer at a time. This buffer is locked when you first enter the set spantree
mst instance or set spantree mst config commands.
If the VLAN is already mapped to some other instance, the VLAN is unmapped fr om that i nstan ce and
mapped to the new instance.
Each time you map a new VLAN or VLANs, they are added to the existing mapping.
All unmapped VLANs are mapped to MST instance 0 (IST ).
Examples This example shows how to map VLANs 400 through 499 to MST instanc e 4 :
Console> (enable) set spantree mst 4 vlan 400-499
Edit Buffer modified. Use 'set spantree mst config commit' to apply the
changes
