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 1-200000000 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.
