Chapter 13 Spanning Tree Protocol
Note: This screen is only available after you activate RSTP on the Switch.

The following table describes the labels in this screen.

LABEL | DESCRIPTION |
Configuration | Click Configuration to specify which STP mode you want to activate. |
| Click RSTP to edit RSTP settings on the Switch. |
|
|
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 the bridge |
| priority plus the 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 |
(second) | a configuration message. The root bridge determines Hello Time, Max |
| Age and Forwarding Delay. |
|
|
Max Age | This is the maximum time (in seconds) a switch can wait without |
(second) | receiving a configuration message before attempting to reconfigure. |
|
|
Forwarding | This is the time (in seconds) the root switch will wait before changing |
Delay (second) | states (that is, listening to learning to forwarding). See Section 13.1.3 |
| on page 149 for information on port states. |
| Note: The listening state does not exist in RSTP. |
|
|
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 | 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. |
