Parameter Description
Priority Device priority is used in selecting the root device, root port, and designated
port. The device with the highest priority becomes the STA root device.
However, if all devices have the same priority, the device with the lowest
MAC address will then become the root device.
Hello Time The time interval (in seconds) at which the root device transmits a
configuration message.
Max Age The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure.
Forward Delay The maximum time (in seconds) the root device will wait before changing
states (i.e., listening to learning to forwarding).
Hold Time The minimum interval between the transmission of consecutive
Configuration BPDUs.
Designated Root The priority and MAC address of the device in the Spanning Tree that this
switch has accepted as the root device.
Root Cost The path cost from the root port on this switch to the root device.
Root Port The number of the port on this switch that is closest to the root. This switch
communicates with the root device through this port. If there is no root port,
then this switch has been accepted as the root device of the Spanning Tree
network.
Reconfig Count The number of times the Spanning Tree has been reconfigured.
Topology Up Time The time since the Spanning Tree was last reconfigured.
