The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning Tree
Configuration, there are six parameters open for the user to configure as
user's idea. Each parameter description is listed below.

0. The figures showing in the screen may not be the exact time it spent
but very close to, because the time is eclipsing.
Time Since Last Topology Change: Time Since Last Topology Change is
the accumulated time in unit of seconds the STP has been since the
last STP Topology Change was made. When Topology Change is initi-
ated again, this counter will be reset to 0. And it will also count again
once STP topology Change is completed.
Function name: STP Configuration
Function Description: User can set the following Spanning Tree parame-
ters to control STP function enable/disable, select mode RSTP/STP and
affect STP state machine behavior to send BPDU in this switch. The default
setting of Spanning Tree Protocol is "Disable".
Parameter Description:
Spanning Tree Protocol: Set 802.1W Rapid STP function Enable /
Disable. Default is "Disable"
Bridge Priority: The lower the bridge priority is, the higher priority it
has. Usually, the bridge with the highest bridge priority is the root. If
you want to have the switch as root bridge, you can set this value
lower than that of bridge in the LAN. The valid value is 0 ~ 61440. The
default is 32768.
Hello Time: Hello Time is used to determine the periodic time to send
normal BPDU from designated ports among bridges. It decides how
long a bridge should send this message to other bridge to tell I am
alive. When the device is the root bridge of the LAN, for example, all
