Spanning
This menu allows you to view and configure the Spanning Tree Protocol.
▲Important: Do not change any of the SpanningTree Protocol parameters unless you are familiar with the IEEE 802.1d specification.

For clarity, the IntraStack device is referred to as a “bridge” in this table.

| 
 | 
 | 
| Priority | Configurable field; integer (from 0 - 65535) used to | 
| 
 | determine the priority of the selected bridge during | 
| 
 | Spanning Tree configuration. | 
| 
 | The lower the value, the higher the bridge priority and | 
| 
 | the more likely it will be selected as a forwarding | 
| 
 | bridge (and possible, the root bridge) in a Spanning | 
| 
 | Tree. | 
| 
 | 
 | 
| Designated Root | |
| 
 | current root bridge in the Spanning Tree. The ID is | 
| 
 | based on its physical address and priority. | 
| 
 | Designated Root is sometimes referred to as Root | 
| 
 | Bridge ID. | 
| 
 | 
 | 
| Root Cost | |
| 
 | the selected bridge to the root bridge, as seen from | 
| 
 | the selected bridge. | 
| 
 | 
 | 
| Root Port | |
| 
 | bridge with the lowest cost route to the current root | 
| 
 | bridge. | 
| 
 | The port is determined during Spanning Tree configu- | 
| 
 | ration. If the selected bridge is the root bridge, the | 
| 
 | value is 0. |
