* You can use “VLAN Port Configuration” on chapter 3 to configure the default priority
for each port.

3.6.3.2.Configuring STA for Ports

The following figure and table describe port STA configuration.

Parameter Default Description
Type

Shows port type as:

100BASE-TX

: 10BASE-T / 100BASE-TX

100BASE-FX :

100BASE-FX

1G BASE-SX/LX : 1000BASE-SX/LX(multimode/ single mode)
1G BASE-T

: 1000BASE-T

Priority

128

Defines the priority for the use of a port in the STA algorithm. If
the path cost for all ports on a switch are the same, the port
with the highest priority (i.e., lowest value) will be configured as
an active link in the Spanning 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, lower values should be
assigned to ports attached to faster media, and higher values
assigned to ports with slower media.
(Path cost takes precedence over port priority.)
The default and recommended range is:

Ethernet: 100

(50~600)

Fast Ethernet:

19 (10~60)

Gigabit Ethernet: 4 (3~10)

The full range is 0 - 65535.
