This is a read only index number of the STP trees.
Active
Select this check box to activate an STP tree. Clear this checkbox to disable an STP tree.
Note: You must also activate Multiple Rapid Spanning Tree in the Advanced Application
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.
Max Age
This is the maximum time (in seconds) a switch can wait without receiving a BPDU before
attempting to reconfigure. All switch ports (except for designated ports) should receive
BPDUs at regular intervals. Any port that ages out STP information (provided in the last
BPDU) becomes the designated port for the attached LAN. If it is a root port, a new root
port is selected from among the Switch ports attached to the network. The allowed range
is 6 to 40 seconds.
