Configuring STA for Ports or Modules
The following figure and table describe STA configuration for ports or
modules. (Note that the Spanning Tree Configuration screen for the
expansion slots also indicates module type.)

Default Description
ENABLED Allows you to enable or disable fast forwarding for
all ports on the switch.
Shows 10/100TX, 100FX, 1000LX or 1000SX port.
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.
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 1 - 65535.
