| 1. | This tree originates from the root bridge
扩充树源自于根桥接器。 |
| 2. | There can be only one root bridge per bridged network
每一个桥接的网路中只可以有一个根桥接器。 |
| 3. | The spanning - tree protocol establishes a root node called the root bridge
扩充树协定建立一个根节点叫根桥接器。 |
| 4. | In this state , switches determine if there are any other paths to the root bridge
在这个状态，交换器会决定是否有任何其他路径可以通到根桥接器。 |
| 5. | When a switch is turned on , the spanning - tree algorithm is used to identify the root bridge
当一个交换器被开机时，扩充树演算法会先去找根桥接器。 |
| 6. | The path that is not the least cost path to the root bridge returns to the blocking state
如果这个路径不是通往根桥接器的最低成本路径，将会回到阻隔状态。 |
| 7. | The root determines values for configuration messages , in the bpdus , and then sets the timers for the other bridges
这个根桥接器在bpdu决定了设定的讯息，然后为其它的桥接器设定计时器。 |
| 8. | These values have been calculated on an assumption that there will be a maximum of seven switches in any branch of the spanning - tree from the root bridge
这些值是在一种假设下所计算出来的，假设从根桥接器衍伸的任何扩充树的分支最多有七个交换器。 |
