- Auto — Device automatically determines the state.
• Point-to-Point Operational Status — Indicates the Point-to-Point operating
state.

MSTP provides differing load balancing scenarios. For example, while port A is
blocked in one STP instance, the same port is placed in the Forwarding State in
another STP instance. The
MSTP Properties page contains information for defining
global MSTP settings, including region names, MSTP revisions, and maximum
hops.
The MSTP section contains the following :
• Defining MSTP Properties
• Defining MSTP Instance to VLAN
• Defining MSTP Instance Settings
• Defining MSTP Interface Settings
