Chapter 46 Configuring Fallback Bridging
Configuring Fallback Bridging
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 bridge group 10:
Switch(config)#
interface gigabitethernet2/0/1
Switch(config-if)#
bridge-group 10 path-cost 20
Adjusting BPDU Intervals
You can adjust BPDU intervals as described in these sections:
•
Adjusting the Interval between Hello BPDUs, page 46-9
(optional)
•
Changing the Forward-Delay Interval, page 46-9
(optional)
•
Changing the Maximum-Idle Interval, page 46-10
(optional)
Note
Each switch in a spanning tree adopts the interval between hello BPDUs, the forward delay interval, and
the maximum idle interval parameters of the root switch, regardless of what its individual configuration
might be.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface
interface-id
Specify the port to set the path cost, and enter interface configuration
mode.
Step 3
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.
Step 4
end
Return to privileged EXEC mode.
Step 5
show running-config
Verify your entry.
Step 6
copy running-config startup-config
(Optional) Save your entry in the configuration file.
