Current MST Instance Configuration
Instance ID
A value used to identify the MST instance. Instance 0 (CIST, Common Internal
Spanning Tree) is a special instance of spanning-tree known as IST or Internal
Spanning Tree (=MSTI00).
VLAN Group
Provide a VLAN group to map this MST instance. Use the VLAN number, for
example: 10. You can set a range, for example: 1-10) or set specific VLANs, for
example: 2,4,6,4-7.
Instance Priority
A value used to identify the MST instance. The MST instance with the lowest value
has the highest priority and is selected as the root. Enter a number 0 through 61440
in increments of 4096.

Note: You must Save the settings ( Page 127 ), if you want to maintain these settings

Port Configuration
Path Cost
The cost of the path to the other bridge from this transmitting bridge at the
specified port. Enter a number from 1 through 200000000.
Priority
Decide which port should be blocked by priority on your LAN. Enter a number
from 0 through 240 in increments of 16.
Link Type
Some of the rapid state transactions that are possible within RSTP are
dependent upon whether the port in question is connected to exactly one other
bridge (that is, it is served by a point-to-point LAN segment), or if it's
connected to two or more bridges (that is, it is served by a shared medium
LAN segment). This configuration allows the p2p status of the link to be
controlled by an administrator.
