Specifying the Configuration on an MST Region

If two or more devices are to be in the same MST region, they must have the same VLAN-to-instance mapping,
the same configuration revision number, and the same MST name.
A region can have one member or multiple members with the same MST configuration; each member must
be capable of processing IEEE 802.1w RSTP BPDUs. There is no limit to the number of MST regions in a
network, but each region can support only up to 65 MST instances. You can assign a VLAN to only one MST
instance at a time.
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
