Mstp Port Information - D-Link DGS-3200 Series User Manual

MSTP Port Information

This window displays the current MSTI configuration information and can be used to update the port configuration for an MSTI
ID. If a loop occurs, the MSTP function will use the port priority to select an interface to put into the forwarding state. Set a higher
priority value for interfaces to be selected for forwarding first. In instances where the priority value is identical, the MSTP
function will implement the lowest MAC address into the forwarding state and other interfaces will be blocked. Remember that
lower priority values mean higher priorities for forwarding packets.
To view the following window, click L2 Features > Spanning Tree > MSTP Port Information:
To view the MSTI settings for a particular port, use the drop-down menu to select the Port number. To modify the settings for a
particular MSTI instance, enter a value in the Instance ID field, an Internal Path Cost, and use the drop-down menu to select a
Priority.
The user may configure the following parameters:
Parameter
Instance ID
Internal Path Cost
Priority
Click Apply to implement the changes made.

Description
The MSTI ID of the instance to be configured. An entry of 0 in this field denotes the CIST
(default MSTI).
This parameter is set to represent the relative cost of forwarding packets to specified ports
when an interface is selected within an STP instance. Selecting this parameter with a value
in the range of 1 to 200000000 will set the quickest route when a loop occurs. A lower
Internal cost represents a quicker transmission. Selecting 0 (zero) for this parameter will set
the quickest route automatically and optimally for an interface.
Enter a value between 0 and 240 to set the priority for the port interface. A higher priority will
designate the interface to forward packets first. A lower number denotes a higher priority.
