Chapter 10 Spanning Tree Protocol
Table 26 Spanning Tree Protocol Status (continued)
LABEL | DESCRIPTION |
Topology | This is the number of times the spanning tree has been reconfigured. |
Changed Times |

|
|
Time Since Last | This is the time since the spanning tree was last reconfigured. |

|
Poll Interval(s) | The text box displays how often (in seconds) this screen refreshes. You may |
| change the refresh interval by typing a new number in the text box and then |
| clicking Set Interval. |

Stop | Click Stop to halt STP statistic polling. |

10.3 Configure STP
To configure STP, click the Configuration link in the Spanning Tree Protocol screen as shown next. Refer to Section 10.1 on page 101 for background information.
Figure 38 Spanning Tree Protocol > Configuration
The following table describes the labels in this screen.

LABEL | DESCRIPTION |
Status | Click Status to display the Spanning Tree Protocol Status screen. |
|
|
Active | Select this check box to activate STP. Clear this checkbox to disable STP. |
|
|
Bridge Priority | Bridge priority is used in determining the root switch, root port and designated port. |
| The switch with the highest priority (lowest numeric value) becomes the STP root |
| switch. If all switches have the same priority, the switch with the lowest MAC |
| address will then become the root switch. Select a value from the |
| box. |
| The lower the numeric value you assign, the higher the priority for this bridge. |
| Bridge Priority determines the root bridge, which in turn determines Hello Time, |
| Max Age and Forwarding Delay. |
|
|
Hello Time | This is the time interval in seconds between BPDU (Bridge Protocol Data Units) |
| configuration message generations by the root switch. The allowed range is 1 to |
| 10 seconds. |
