Parameter
Description
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.
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.
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, a new root port is selected
from among the Switch ports attached to the network. The allowed range is 6 to 40
seconds.
Max Hops
Instance
Selects an instance which you want to configure.
Priority
Configures the priority for the instance.
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 root switch. If
all switches have the same priority, the switch with the lowest MAC address will then
become the root switch.
Enter a value from 0~61440.
The lower the numeric value you assign, the higher the priority for this bridge.
Priority determines the root bridge, which in turn determines the Root Hello Time,
Root Maximum Age and Root Forwarding Delay.
