FOR

 STA

Use the RSTP Port Configuration page to configure RSTP attributes for 

specific interfaces, including path cost, port priority, edge port (for fast 

forwarding), automatic detection of an edge port, and point-to-point link 

type.

P

ARAMETERS

The following parameters are displayed on the RSTP Port Configuration 

page: 

◆

Port

 – Port identifier. (Range: 1-28)

This field is not applicable to static trunks or dynamic trunks created 

through LACP. Also, note that only one set of interface configuration 

settings can be applied to all trunks.

◆

RSTP Enabled

 – Enables RSTP on this interface. (Default: Enabled)

◆

Path Cost

 – This parameter is used by the STA 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.)
