Parameter Description
Spanning Tree Protocol Settings
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) or Multiple Spanning Tree Protocol (MSTP).
Forward
Time
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 age out STP information (provided in the last BPDU) becomes
the designated port for the attached LAN. If it is a root port, anew 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.
Priority
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
