Configuring STA for Ports
The following figure and table describe port STA configuration.
Note: Fast Forwarding enables end-node workstations and servers to overcome
time-out problems when the Spanning Tree Algorithm is implemented in a
network. Therefore, Fast Forwarding should only be enabled for ports connected
to an end-node device.

Parameter Default Description
Fast forwarding
on all ports
Enabled See “FastForwarding” in this table.
Type Shows port type as:
10/100TX
: 10BASE-T / 100BASE-TX
100FX : 100BASE-FX
1000SX : 1000BASE-SX
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.
Fast Forwarding Enabled This parameter is used to enable/disabled the Fast Spanning Tree
mode for the selected port. In this mode, ports skip the Blocked,
Listening and Learning states and proceed straight to Forwarding.
