Example usage:
To designate ports 1 through 5, with instance id 2, to have an auto internalCost and a priority of 16:
DES-1228/ME:4#config stp mst_ports 1-5 instance_id 2 internalCost auto priority 16
Command : config stp mst_ports 1-5 instance_id 2 internalCost auto priority 16
Success.

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.
<portlist> − Specifies a port or range of ports to be configured.
instance_id <value 0-8> − Enter a numerical value between 0 and 8 to identify the
instance_id previously configured on the Switch. An entry of 0 will denote the CIST
(Common and Internal Spanning Tree).
internalCost – 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
auto. There are two options:
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 internalCost
represents a quicker transmission.
priority <value 0-240> − 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.
Only Administrator-level users can issue this command.
