Book Title
To return to the default path cost, use the no bridge-group bridge-group path-cost cost interface
configuration command.
Adjusting BPDU Intervals
You can adjust bridge protocol data unit (BPDU) intervals as described in these sections:
• Adjusting the Interval Between Hello BPDUs, page 83
• Changing the Forward-Delay Interval, page 84
• Changing the Maximum-Idle Interval, page 85
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
Follow the steps below to adjust the interval between hello BPDUs.
SUMMARY STEPS
1. enable
2. configure terminal
3. bridge bridge-group hello-time seconds
4. end
5. show running-config
Step 4
bridge bridge-group path-costs cost
Example:
Router(config-if)# bridge 100
pathcost 4
Changes the path cost.
Step 5
end
Example:
Router(config-if)# end
Returns to privileged EXEC mode.
Step 6
show running-config
Example:
Router: show running-config
Verifies your entry.
Step 7
copy running-config startup-config
Example:
Router# copy running-config
startup-config
(Optional) Saves your entry in the configuration file.
