MSTP Port Information
This window displays the current MSTI configuration information and can be used to 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 interfaces 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. Remember that lower priority values mean higher priorities for forwarding packets.
