This example shows how to enable MST on the switch:

Entering MST Configuration Mode
You enter MST configuration mode to configure the MST name, VLAN-to-instance mapping, and MST
revision number on the switch.
For two or more switches to be in the same MST region, they must have the identical MST name,
VLAN-to-instance mapping, and MST revision number.
Each command reference line creates its pending regional configuration in MST configuration mode. In
Note
addition, the pending region configuration starts with the current region configuration.
When you are working in MST configuration mode, note the difference between the exit and abort commands.
