Configuring STA for Ports
The following figure and table describe port STA configuration.

Description
Shows port type as:
100BASE-TX:
100BASE-FX-MM: 100BASE-FX (multimode)
100BASE-FX-SM:
1GBase-SX:
1GBase-LX:
1GBase-T:
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.)
