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.  
The default and recommended range is:

Standard Ethernet: 100 (50~600)

Fast Ethernet: 

19 (10~60)

Gigabit Ethernet: 

4 (3~10)

The full range is 1 - 65535.
Note: Path cost takes precedence over port priority. 

Fast Forward Enabled

This enables/disables Fast Forwarding for the selected 

port. In this mode, ports skip the Blocked, Listening and 

Learning states and proceed straight to Forwarding. 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 that are 

connected to an end-node device.
