MST ID
Displays the ID of the MST group that is created. A maximum of 15
groups can be set for the Switch.
Port
Displays port or trunked port ID.
Priority
Select the bridge priority value for the MST. When switches or bridges
are running STP, each is assigned a priority. After exchanging BPDUs,
the Switch with the lowest priority value becomes the root bridge. The
bridge priority is a multiple of 4096. If you specify a priority that is not
a multiple of 4096, the priority is automatically set to the next lowest
priority that is a multiple of 4096. For example, if you set the priority
to any value from 0 through 4095, the priority is set to 0. The default
priority is: 32768. The valid range is from 0 to 61440.
Internal Path
Cost Conf
The Internal Path Cost setting allows you to specify the relative cost
of sending spanning tree traffic through the interface to adjacent
bridges within a spanning tree region.
