•
Bridge Priority—Set the priority of this bridge for the selected
MST instance
•
Action—Select either add VLAN or remove VLAN
•
VLANs—Displays the VLANs mapped to the selected instance The default
mapping is that all VLANs are mapped to the common and internal
spanning tree (CIST) instance 0)
STEP 8 Click Apply The MSTP properties are defined, and the Running
Configuration file is updated
MSTP Instance Status
The MSTP Instance Status page enables you to configure and view parameters
per MST instance This is the per-instance equivalent to the Spanning Tree page
To enter MSTP instance settings:
STEP 1 Click Configuration > Spanning Tree Management > MSTP Instance
Status
STEP 2 The following parameters are shown
•
Instance ID—Select an MST instance to be displayed and defined
•
Bridge Priority—Set the priority of this bridge for the selected
MST instance
•
Designated Root Bridge ID—Displays the priority and MAC address of the
Root Bridge for the MST instance
•
Root Port—Displays the root port of the selected instance
•
Root Path Cost—Displays the root path cost of the selected instance
•
Bridge ID—Displays the bridge priority and the MAC address of this
device for the selected instance
•
Remaining Hops—Displays the number of hops remaining to the next
destination
MSTP Instance Interface
The MSTP Instance Interface page enables you to configure the port MSTP
settings for every MST instance, and to view information that has currently been
learned by the protocol, such as the designated bridge per MST instance
To configure the ports in an MST instance:
STEP 1 Click Configuration > Spanning Tree Management > MSTP Instance
Interface
STEP 2 Enter the parameters
•
MSTP Instance—Select the MSTP instance to be configured
•
Interface Type—Select whether to display the list of ports or LAGs
STEP 3 Click Search The following MSTP parameters for the interfaces on
the instance are displayed:
•
Interface—Select the interface for which the MSTI settings are to be
defined Interface Priority—Set the port priority for the specified interface
and MST instance
•
Path Cost—Enter the port contribution to the root path cost in the User
Defined textbox or select Use Default to use the default value
•
Port State—Displays the MSTP status of the specific port on a specific
MST instance The parameters are defined as:
•
Disabled—STP is currently disabled
•
Blocking—The port on this instance is currently blocked, and cannot
forward traffic (with the exception of BPDU data) or learn MAC
addresses
•
Listening—The port on this instance is in Listening mode The port
cannot forward traffic, and cannot learn MAC addresses
•
Learning—The port on this instance is in Learning mode The port
cannot forward traffic, but it can learn new MAC addresses
•
Forwarding—The port on this instance is in Forwarding mode The
port can forward traffic and learn new MAC addresses
•
Boundary—The port on this instance is a boundary port It inherits
its state from instance 0 and can be viewed on the STP Interface
Settings page
•
Port Role—Displays the port or LAG role, per port or LAG per instance,
assigned by the MSTP algorithm to provide STP paths:
•
Root—Forwarding packets through this interface provides the lowest
cost path for forwarding packets to the root device
•
Designated—The interface through which the bridge is connected
to the LAN, which provides the lowest root path cost from the LAN to
the Root Bridge for the MST instance
