Configuring Fallback Bridging
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 g rou p 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, page46-8 (optional)
•Changing the Forward-Delay Interval, page46-9 (optional)
•Changing the Maximum-Idle Interval, page 46-9 (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.

Adjusting the Interval between Hello BPDUs

Beginning in privileged EXEC mode, follow these step to adjust the interv al between hello BPDU s. This
procedure is optional.
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.

Step1 configure terminal Enter global configuration mode.
Step2 bridge bridge-group hello-time seconds Specify the interval between hello BPDUs.
•For bridge-group, specify the bridge group number. The range is 1
to 255.
•For seconds, enter a number from 1 to 10. The defau lt is 2.
Step3 end Return to privileged EXEC mode.
