Using the 7C0x SmartSwitch Bridge View
Root Forward Delay
The Forward Delay (in seconds) that will be implemented by this bridge if it is the Root or becomes the Root. (The Root Bridge in the network sets the Forward Delay for all bridges in the Spanning Tree network.)
The IEEE 802.1d specification recommends that Forward Delay = 15 seconds, with an allowable range of 4 to 30 seconds.
To ensure proper operation of the Spanning Tree Algorithm, the IEEE 802.1d specification
TIP recommends that you always observe the following relationship between Forward Delay and Max Age:
2 x (Forward Delay - 1.0) > Max Age
Root Max Age
The Max Age value (in seconds) that will be implemented if this bridge is the Root or becomes the Root. (The Root Bridge in the network sets the Max Age for all bridges in the Spanning Tree network.)
The IEEE 802.1d specification recommends that Max Age = 20 seconds, with an allowable range of 6 to 40 seconds.
Root Hello Time
The Hello Time that will be implemented if this bridge is the Root or becomes the Root.
The IEEE 802.1d specification recommends that Hello Time = 2 seconds, with an allowable range of 1 to 10 seconds.
The Spanning Tree Port Table button opens the window in which you set Spanning Tree parameters for individual bridge ports; see The Spanning Tree Port Parameters Window, page
Changing Spanning Tree Parameters
To change the Bridge Priority, Root Forward Delay, Root Max Age, or Root Hello Time:
1.In the Spanning Tree Protocol window, highlight the current value of the field you want to change.
2.Type the new value in the appropriate text box and press Enter or Return on the keyboard.
