config stp mst_ports
| higher priority value for interfaces to be selected for forwarding |
| first. In instances where the priority value is identical, the MSTP |
| function will implement the lowest port number into the forwarding |
| state and other interfaces will be blocked. Remember that lower |
| priority values mean higher priorities for forwarding packets. |
Parameters | <portlist> - Specifies a port or range of ports to be configured. The |
| port list is specified by listing the lowest slot number and the |
| beginning port number on that slot, separated by a colon. Then |
| the highest slot number, and the highest port number of the range |
| (also separated by a colon) are specified. The beginning and end |
| of the port list range are separated by a dash. For example, 1:3 |
| specifies slot number 1, port 3. 2:4 specifies slot number 2, port |
| 4. |
| 2, port 4 − in numerical order. |
| instance_id <value |
| 15 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 |
| in the range of |
| loop occurs. A lower internalCost represents a quicker |
| transmission. |
| priority <value |
| the priority for the port interface. A higher priority will designate the |
| interface to forward packets first. A lower number denotes a |
| higher priority. |
Restrictions | Only |

Example usage:
To designate ports 1 through 5 on module one, with instance ID 2, to have an auto internalCost and a priority of 16:
Command : config stp mst_config_id ports
Success.
