Spanning Tree > STP Status
You can display a summary of the current bridge STA information that applies to the entire Switch using the information screen.. This screen displays the following information..
Spanning Tree State Shows if the Switch is enabled to participate in an
Spanning Tree Mode Shows the type of protocol that the Switch is using..
Bridge ID A unique identifier for this bridge, consisting of the bridge priority and MAC address (where the address is taken from the Switch system)..
Designated Root The priority and MAC address of the device in the Spanning Tree that the Switch has accepted as the root device..
Root Port The number of the port on the Switch that is closest to the root.. The Switch communicates with the root device through this port.. If there is no root port, then the Switch has been accepted as the root device of the Spanning Tree network..
Root Path Cost The path cost from the root port on the Switch to the root device..
Root Maximum Age The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure.. All device ports (except for designated ports) should receive configuration messages at regular intervals.. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN.. If it is a root port, a new root port is selected from among the device ports attached to the network.. (References to “ports” in this section mean “interfaces,” which includes both ports and LAGs..)
Root Hello Time Interval (in seconds) at which the Switch transmits a configuration message..
Root Forward Delay The maximum time (in seconds) the root device will wait before changing states (i..e.., discarding to learning to forwarding).. This delay is required because every device must receive information about topology changes before it starts to forward frames.. In addition, each port needs time to listen for conflicting information that would make it return to a discarding state; otherwise, temporary data loops might result..
Topology Changes Counts The number of times the Spanning Tree has been reconfigured..
Last Topology Change Time since the Spanning Tree was last reconfigured..
Spanning Tree > Global STP
Spanning Tree > Global STP
Configure the global settings for STP using this screen.. Global settings apply to the entire Switch..
Spanning Tree State Enables/disables STP on the Switch.. Use the checkbox to enable or disable STP on the Switch.. (Default: Enabled)
