Configuration

STP includes Rapid Spanning Tree Protocol (RSTP). STP has six parameters to be configured.
These parameters are described below.
Function name:
STP Configuration
Function description:
Set the following Spanning Tree parameters to control STP function (enable/disable). Select mode
RSTP/STP and affect STP state machine behavior to send BPDU in the switch. The default setting
of STP is Disable.
Parameter description:
Spanning Tree Protocol:
Set 802.1W Rapid STP function Enable / Disable. Default is Disable.
Bridge Priority:
The lower the number for bridge priority, the higher the priority it will have. Usually, the bridge
with the highest bridge priority is the root. If you want this switch to be the root bridge, set the
value lower than that of the 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 notify other bridges to say that it is up and
connected. If the GSM switch is the root bridge of the LAN, for example, all other bridges will
use the hello time assigned by this switch to communicate with each other. The valid value is 1
~ 10 in unit of seconds.
Default is 2 seconds.
