Figure 40 Spanning Tree Protocol: Status
The following table describes the labels in this screen.

LABEL | DESCRIPTION |
|
|
Spanning Tree | This field displays Running if STP is activated. Otherwise, it displays Down. |
Protocol |
|
Configuration | Click Configuration to configure STP settings. Refer to Section 11.3 on page 84. |
|
|
Bridge | Root refers to the base of the spanning tree (the root bridge). Our Bridge is this |
| switch. This switch may also be the root bridge. |
Bridge ID | This is the unique identifier for this bridge, consisting of bridge priority plus MAC |
| address. This ID is the same for Root and Our Bridge if the switch is the root |
| switch. |
Hello Time | This is the time interval (in seconds) at which the root switch transmits a |
(second) | configuration message. The root bridge determines Hello Time, Max Age and |
| Forwarding Delay |
Max Age (second) | This is the maximum time (in seconds) a switch can wait without receiving a |
| configuration message before attempting to reconfigure. |
Forwarding Delay | This is the time (in seconds) the root switch will wait before changing states (that |
(second) | is, listening to learning to forwarding). |
Cost to Bridge | This is the path cost from the root port on this switch to the root switch. |
|
|
Port ID | This is the priority and number of the port on the switch through which this switch |
| must communicate with the root of the Spanning Tree. |
Topology Changed | This is the number of times the spanning tree has been reconfigured. |
Times |
|
Time Since Last | This is the time since the spanning tree was last reconfigured. |
