Using the BayStack 350 10/100 Autosense Switch
Table 3-14. Spanning Tree Switch Settings parameters (continued)
Parameter | Description |
|
Forward Delay | Indicates the Forward Delay parameter value that the root bridge is currently using. This | |
| value specifies the amount of time that the bridge ports remain in the Listening and | |
| Learning states before entering the Forwarding state. | |
| Note that the root bridge’s Forward Delay parameter value becomes the (actual) Forward | |
| Delay parameter value for all bridges participating in the spanning tree network. See also | |
| Bridge Forward Delay. | |
| Default Value | 15 |
| Range | 4 to 30 seconds |
Bridge Hello | Indicates the Hello interval (the amount of time between transmissions of Configuration | |
Time | Bridge PDUs) specified by management for this bridge. This parameter takes effect only | |
| when this bridge becomes the root bridge. | |
| Note that, although you can set the Hello interval for a bridge using bridge management | |
| software, once the spanning tree computation process is complete, all bridges | |
| participating in the spanning tree network use the root bridge’s Hello Interval parameter | |
| value. If any bridge becomes the root bridge, its Hello Interval parameter value becomes | |
| the (actual) Hello Interval parameter value for all bridges participating in the spanning | |
| tree network. See also Hello Time. | |
| Default Value | 2 |
| Range | 1 to 10 seconds |
Bridge | Specifies the maximum age (in seconds) that a Hello message can attain before it is | |
Maximum Age | discarded. This parameter, set for this bridge by management, takes effect only when | |
Time | this bridge becomes the root bridge. | |
| Note that, if this bridge becomes the root bridge, its Maximum Age Time parameter value | |
| becomes the (actual) Maximum Age Time parameter value for all bridges participating in | |
| the spanning tree network. See also Maximum Age Time. | |
| Default Value | 20 |
| Range | 6 to 40 seconds |
Bridge Forward | Indicates the Forward Delay parameter value specified by management for this bridge. | |
Delay | This parameter takes effect only when this bridge becomes the root bridge. | |
| The Forward Delay parameter value specifies the amount of time that the bridge ports | |
| remain in the Listening and Learning states before entering the Forwarding state. | |
| Note that all bridges participating in the spanning tree network use the root bridge’s | |
| Forward Delay parameter value. See also Forward Delay. | |
| Default Value | 15 |
| Range | 4 to 30 seconds |
