Parameter Default Description
Priority 128 Defines the priority for the use of a port in the STA
algorithm. If the path cost for all po rts on a switch
are the same, the port with the highest priority (i.e.,
lowest value) will be con figured as an active link
in the spannin g tree. Where more than one port is
assigned the highest priority, the port with lowest
numeric identifier will be enabled.
The range is 0 - 255.
(Path) Cost 100/19/4 This parameter is used by the STA algorithm to
determine the best path between devices.
Therefore, lo wer values should be assigned to
ports attached to faster media, and higher values
assigned to ports with slower media.
The default and recommen ded range is:
Standard Ethernet: 100 (50~600)
Fast Ethern et:
19 (10~60)
Gigabit Ethernet: 4 (3~10)
The full range is 0 - 65535.
Note: Path cost takes prec edence over por t priority.
Fast STA
Mode Disabled This enables/disables the Fast STA Mode for the
port. In this mode, ports skip the Blocked,
Listening and Learning states and proceed straight
to Fo rwarding. The Fast STA Mode enables
end-node workstations and servers to overc ome
time-out problems when the Spanning Tree
Algorithm is implemented in a network. Therefore,
the Fast STA Mode should only be enabled fo r
ports that are connec ted to an end-node device.
