Using the TSX-1620 Bridge View
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.
The Spanning Tree Port Parameters Window
The Spanning Tree Algorithm ensures that only a single bridge path exists 
between any two end stations in a network designed with multiple bridges 
placed in parallel; it also ensures that on any given bridge, only one port path 
exists between the bridge and any one network segment. In the Spanning Tree 
Port Table you can view and edit the Spanning Tree values for individual ports; 
the Spanning Tree Port parameters affect a port’s participation in the Spanning 
Tree.
To open the Spanning Tree Port Table window:
1.
Display the Device menu by clicking on the Front Panel 
 button.
2.
Drag down to Spanning Tree to open the Spanning Tree Protocol window.
3.
In the Spanning Tree Protocol window, click on the Spanning Tree  Port Table 
button.
or
1.
In the Bridge Traffic View, click mouse button 3 on a port to display the Port 
menu and drag down to Spanning Tree.
The scroll list at the top of the window lists each bridge port available on the 
device and its current port priority. Below the Port List, the window includes the 
following:
Priority (Port)
If two or more ports on the same bridge are connected to the same network 
segment, each port will receive the same device-level values for Root ID, Root 
Cost, and Bridge ID in Configuration BPDUs. In this case, the BPDU’s port-level 
information—the transmitting port’s identifier and its manageable Priority 
NOTE
Setting Spanning Tree Port Parameters only affects port selection on a particular bridge; 
settings do not affect the TSX-1620’s device-level priority in the network’s Spanning Tree.
