Spanning Tree
The configuration page for Spanning Tree Protocol can disable and enable the
feature in runtime. This page consists of three parts.
The first part shows the root information. It tells user the STP setting about the
root switch.
The second part is the STP setting. The following options are available:
Disable/STP Enable/RSTP Enabled: Turn the STP/RSTP off/on. When
you turn the STP/RSTP on, STP/RSTP will use the following settings if the
switch is the root switch.
Hello Time: the interval between the generation of configuration BPDU
Max Age: a timeout value to be used by all Bridges in the LAN
Forward Delay: a timeout value to be used by all bridges in the LAN
Bridge Priority: the switch priority in the LAN
The third part is the port setting. It contains a display window to show the
current configuration for each port. You click
to change the port
setting for STP/RSTP. The following fields are available:
Port: select the corresponding port to configure
Priority: the port priority in the switch. Low numeric value indicates a high
priority. The port with lower priority is more likely to be blocked by STP if a
network loop is detected. The valid value is from 0 to 255.
Cost: the valid value is from 1 to 65535. The higher cost is more likely to
be blocked by STP if a network loop is detected.
FastLink: make the port in forwarding state when a link comes up, then
the port will participate STP resolutions.
