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
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 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.
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 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.
Pathcost
Path cost is the cost of transmitting a frame on to a LAN through that port. It is recommended
to assign this value according to the speed of the bridge. The slower the media, the higher
the cost.
