Assigning A Path Cost - Cisco Catalyst 3550 series Software Configuration Manual

Chapter 36 Configuring Fallback Bridging
Command
Step 5 show running-config
Step 6
copy running-config startup-config
No no form of this command exists. 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 of an interface to 20 in bridge group 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:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
bridge-group bridge-group path-cost
cost
Step 4 end
Step 5
show running-config
Step 6
copy running-config startup-config
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 on an interface to 20 in bridge group 10:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# bridge-group 10 path-cost 20

Purpose
Verify your entry.
(Optional) Save your entry in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the interface to set the
path 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.
–
Return to privileged EXEC mode.
Verify your entry.
(Optional) Save your entry in the configuration file.
