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. |
