USING THE SYSTEM CONFIGURATION PROGRAM
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. |
