Assigning A Path Cost - Cisco WS-C3560-48PS-S Software Configuration Manual

Chapter 34 Configuring Fallback Bridging
Command
Step 5 show running-config
Step 6
copy running-config startup-config
To return to the default setting, use the no bridge-group bridge-group priority interface configuration
command.
This example shows how to change the priority to 20 on a port in bridge group 10:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# bridge-group 10 priority 20

Assigning a Path Cost

Each port has a path cost associated with it. By convention, the path cost is 1000/data rate of the attached
LAN, in Mbps.
Beginning in privileged EXEC mode, follow these steps to assign a path cost. This procedure is optional.
Command
Step 1 configure terminal
Step 2

Step 4 end
Step 5
show running-config
Step 6

To return to the default path cost, use the no bridge-group bridge-group path-cost interface
configuration command.
This example shows how to change the path cost to 20 on a port in bridge group 10:
Switch(config)# interface gigabitethernet0/1

(Optional) Save your entry in the configuration file.
Purpose
Enter global configuration mode.
Specify the port to set the path cost, and enter interface configuration
mode.
Assign the path cost of a port.
• For bridge-group, specify the bridge group number. The range is 1
to 255.
• For cost, enter a number from 0 to 65535. The higher the value, the
higher the cost.
– For 10 Mbps, the default path cost is 100.
– For 100 Mbps, the default path cost is 19.
For 1000 Mbps, the default path cost is 4.
