The SSR bridge will use the specified STP settings. However, individual ports also have
STP settings that you can configure as discussed in
Individual Port" on page

ports.
•
Port priority
The STP algorithm uses the port priority to determine which port to use if a bridge has
two ports connected in a loop.
•
Port cost
This attribute specifies how much a port contributes to the total cost of the path to the
root bridge when the port is the root.
A port uses the default settings for these attributes. You may, however, change these
default settings on individual ports. To change a port's priority or cost:
1.
Start Configuration Expert if you have not already done so.
2.
Open the configuration file you want to modify and then double-click that file's
Bridging Configuration object.
3.
Double-click the Spanning Tree Protocol object.
4.
In the list of STP objects that appears, double-click the Port Specific STP Settings
object.
Configuration Expert displays the Configure New Port object and objects for any
previously configured ports.
5.
Do one of the following:
–
If you are configuring a port's STP attributes for the first time, select the Configure
STP Settings on a New Port object.
–
If you are modifying existing STP settings of a port, select that port's object from
the list that appeared after you expanded the Port Specific STP Settings object.
