STA Port Configuration

The following figure and table describe STA configuration for ports or
modules.

Parameter

Default

Description

Fast

Forwarding

Mode
(All Ports)

Enabled

See “Fast Forward” in this table.

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 is 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.
