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.
