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 selecte d for forwa rding first. In instances where t he priority value is ide ntical, the MST P
function will im plement the lowest MAC ad dress into the forwarding state an d other interfaces will b e 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 setting s for a p articular port, use the drop-down menu to select th e Port number. To modify the settings for a
particular MSTI instance, click the Edit button and then enter a value in the Internal Path Cost field and use the drop-down menu
to select a value for Priority.
The user may configure the following parameters:

Description
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.
