• Remaining Hops – The remaining number of hop counts for the MST instance.
• Transmission Limit – The minimum interval between the transmission of
consecutive RSTP/MSTP BPDUs.
• Path Cost Method – The path cost is used to determine the best path between
devices. The path cost method is used to determine the range of values that can
be assigned to each interface.
• Flooding Behavior – Shows if the system is configured to flood BPDUs to all other
ports on the switch or just to all other ports in the same VLAN when spanning tree
is disabled globally on the switch or disabled on a specific port.
Web – Click Spanning Tree, STA, Information.

CLI – This command displays global STA settings, followed by settings for each port.
Note: The current root port and current root cost display as zero when this device is not
connected to the network.
