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 1-2000000 - Selecting this parameter with a value in the range of 1-2000000
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. This entry must be divisible by 16. The default priority setting is 128.
