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.
To view the following window, click
L2 Features > Spanning Tree > MSTP Port Information
