the Switch with the lowest priority value becomes the root bridge. The
default value is: 32768. The range is from 0 to 61440. The bridge
priority is a multiple of 4096.

MST Port Settings
This page displays the current MSTI configuration information for the Switch. From here you can
update the port configuration for an MSTI ID. If a loop occurs, the MSTP function will use the port
priority to select an interface to put into the forwarding state. Set a higher priority value for ports
you wish to be selected for forwarding first. In 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. Note that a lower priority values mean higher priorities for forwarding
packets.
