Figure 7- 35. MSTI Settings window
Description
Displays the MSTI ID of the instance being 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 a STP instance. The default setting is 0 (auto). There are
two options:
•
0 (auto) - Selecting this parameter for the internalCost will set quickest route
automatically and optimally for an interface. The default value is derived from the
media speed of the interface.
•
value 1-200000000 - 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.
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.
