Mapping or Unmapping a VLAN to an MST Instance—CLI Version
If two or more bridges are to be in the same MST region, they must have the identical MST name,
VLAN-to-instance mapping, and MST revision number.
You cannot map VLANs 3968 to 4047 or 4094 to any MST instance. These VLANs are reserved for internal
use by the device.
When you change the VLAN-to-MSTI mapping, the system reconverges MST.
Note
You cannot disable an MSTI.
Note
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
