MSTP operation maps VLANs into STP instances. Packets
assigned to various VLANs are transmitted along different
paths within Multiple Spanning Trees Regions (MST
Regions). Regions are one or more Multiple Spanning
Tree bridges by which frames can be transmitted. In
configuring MST, the MST region to which the device
belongs is defined. A configuration consists of the name,
revision, and region to which the device belongs.
Network Administrators can define MSTP Instances
settings using the MSTP Instance Settings screen.
Defines the VLAN group to which the
Instance ID
interface is assigned.
Maps the selected VLAN to the selected
Included VLAN
instance. Each VLAN belongs to one instance.

are displayed.
Indicates whether the port is enabled for the
Port State
specific instance.
Indicates if the port is a point-to-point port, or a
Type
port connected to a hub. The possible field values are:
Indicates the port is a boundary port.
Boundary Port
A Boundary port attaches MST bridges to LAN in an
outlying region. If the port is a boundary port, it also
indicates whether the device on the other side of the
link is working in RSTP or STP mode.
Indicates the port is a master port. A
Master Port
Master port provides connectivity from a MSTP region
to the outlying CIST root.
Indicates the port is an internal port.
Internal
Indicates the port role assigned by the STP algorithm
