Chapter44 Configuring Fallback Bridging
Configuring Fallback Bridging
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 gigabitethernet2/0/1
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 100 0/data rate of the attached
LAN, in Mb/s.
Beginning in privileged EXEC mode, follow these steps to assign a path cost. This procedure is optional.
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 bri dge group 10:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# bridge-group 10 path-cost 20

Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Specify the port to set the path cost, and enter interface configuration
mode.
Step3 bridge-group bridge-group path-cost
cost
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 Mb/s, the default path cost is 100.
–
For 100 Mb/s, the default path cost is 19.
–
For 1000 Mb/s, the default path cost is 4.
Step4 end Return to privileged EXEC mode.
Step5 show running-config Verify your entry.
Step6 copy running-config startup-config (Optional) Save your entry in the configuration file.
