Chapter26 Configuring Fallback Bri dging Configuring Fallback Bridging
No no form of this command exists. To return to the default setting, use the bridge-group bridge-group
priority number interface configuration command.
This example shows how to change the priority of an interfa c e t o 20 i n bri dge g rou p 10:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# bridge-group 10 priority 20
Assigning a Path Cost
Each interface 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:
To return to the default path cost, use the no bridge-group bridge-group path-cost cost interface
configuration command.
This example shows how to change the path cost on an interface to 10 in bridge group 10:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# bridge-group 10 path-cost 20

Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Enter interface configuration mode, and specify the interface to set the
path cost.
Step3 bridge-group bridge-group path-cost
cost Assign the path cost of an interface.
•For bridge-group, specify the bridge group number. The range is 1
to 255.
•For cost, enter a number from 1 to 65536. 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.
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.
