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.

Select the port you want to configure.
The MSTI ID of the instance to be configured. Enter a value between 0 and 15. 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
