Description
Select the unit you want to configure.
Select the port you want to configure.
The MSTI ID of the instance to be configured. Enter a value between 0 and 64. 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 will designate the interface to forward packets first. A lower number denotes a
higher priority.
