DESCRIPTION
Tree
This is the index number of the STP trees.
Active
Select this check box to activate an STP tree. Clear this check box to disable an STP tree.
Note: You must also activate Multiple Rapid Spanning Tree (MRSTP) in the
Bridge Priority
Bridge priority is used in determining the root switch, root port and designated port. The switch
with the highest priority (lowest numeric value) becomes the STP root switch. If all switches
have the same priority, the switch with the lowest MAC address will then become the root
switch. Select a value from the drop-down list box.
The lower the numeric value you assign, the higher the priority for this bridge.
Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age and
Forwarding Delay.
Hello Time
This is the time interval in seconds between BPDU (Bridge Protocol Data Units) configuration
message generations by the root switch. The allowed range is 1 to 10 seconds.
