Parameter

Default

Description

 

 

 

Fast forwarding mode

ENABLED

Allows you to enable or disable fast forwarding for

of all ports

 

 

all ports on the switch.

Type

 

 

Shows the port type as 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.
