4.3.2.2. Web Configuration
Parameter Description
State
Select Enabled to use Spanning Tree Protocol (STP) or Rapid
Spanning Tree Protocol (RSTP).
Mode
Select to use either Spanning Tree Protocol (STP) or Rapid
Spanning Tree Protocol (RSTP).
Forward Delay
This is the maximum time (in seconds) the Switch will wait
before changing states. This delay is required because every
switch must receive information about topology changes before
it starts to forward frames. In addition, each port needs time to
listen for conflicting information that would make it return to a
blocking state; otherwise, temporary data loops might result.
The allowed range is 4 to 30 seconds.
Max Age
This is the maximum time (in seconds) the 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.
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.
