8. spanning-tree mst instance-id port-priority
priority
Configures the port priority.
 instance-id—Specifies a single instance, a range of
instances separated by a hyphen, or a series of
instances separated by a comma. The range is 0 to
4096.
 priority—The range is 0 to 240 in increments of 16. The
default is 128. The lower the number, the higher the
priority.
The priority values are 0, 16, 32, 48, 64, 80, 96, 112,
128, 144, 160, 176, 192, 208, 224, and 240. All other
values are rejected.
9. spanning-tree mst instance-id cost cost Configures the cost.
If a loop occurs, the MSTP uses the path cost when selecting
an interface to place into the forwarding state. A lower path
cost represents higher-speed transmission.
 instance-id—Specifies a single instance, a range of
instances separated by a hyphen, or a series of
instances separated by a comma. The range is 0 to
4096.
 cost—The range is 1 to 200000000; the default value is
derived from the media speed of the interface.
10. spanning-tree link-type point-to-point Specifies that the link type of a port is point-to-point.
11. spanning-tree mst pre-standard Specifies that the port can send only prestandard BPDUs.
12. end Returns to privileged EXEC mode.
