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. |
Configuration | The number of times the Spanning Tree has been reconfigured. |
Changes |

Topology Up Time The time since the Spanning Tree was last reconfigured.
