Forward Delay (4~30 sec) | This time value, measured in units of a second, controls |
| how fast a port changes its spanning state when moving |
| towards the Forwarding state. The value determines |
| how long the port stays in each of the Listening and |
| Learning states, which precede the Forwarding state. |
| This value is also used, when a topology change has |
| been detected and is underway, to age all dynamic |
| entries in the Forwarding Database. |
|
|
Root Path Cost | The cost of the path to the root device as seen from this |
| bridge. |
|
|
Configuration Changes | The total number of topology changes detected by this |
| bridge since the management entity was last reset or |
| initialized. |
|
|
Last Topology Change | The time (in a second) since the last time a topology |
| change was detected by the bridge entity. |

|
Usage | Enable/Disable this switch to join in/withdraw from a STA |
| compliant network |
|
|
Priority (1~65535) | Priority is a decisive key for selecting root device, root |
| port, and designated port. The smaller number, the higher |
| priority. 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 |
| become the root device |
|
|
Hello Time (1~10sec) | The amount of time between the transmission of |
| Configuration bridge PDUs by this node on any port when |
| it is the root of the spanning tree or trying to become so, in |
| units of a second. This is the actual value that this bridge |
| is currently using |
|
|
Maximum Age (6~40sec) | The maximum age of Spanning Tree Protocol information |
| learned from the network on any port before it is |
| discarded, in units of a second. This is the actual value |
| that this bridge is currently using |
|
|
Forward Delay (4~30sec) | This time value, measured in units of a second, controls |
| how fast a port changes its spanning state when moving |
| towards the Forwarding state. The value determines how |
| long the port stays in each of the Listening and Learning |
