Chapter 2: Bridging Configuration Guide
To set an interface priority, enter the following command in Configure mode:
Assign Port Costs
Each interface has a port cost associated with it. By convention, the port cost is 1000/data
rate of the attached LAN, in Mbps. You can set different port costs.
To assign port costs, enter the following command in Configure mode:
Adjust Bridge Protocol Data Unit (BPDU) Intervals
You can adjust BPDU intervals as described in the following sections:
• Adjust the Interval between Hello BPDUs
• Define the Forward Delay Interval
• Define the Maximum Idle Interval
Adjust the Interval between Hello Times
You can specify the interval between hello time.
To adjust this interval, enter the following command in Configure mode:
Define the Forward Delay Interval
The forward delay interval is the amount of time spent listening for topology change
information after an interface has been activated for bridging and before forwarding
actually begins.
To change the default interval setting, enter the following command in Configure mode:
Establish a priority for a specified
interface.
stp set port
<port-list>
priority
<num>
Set a different port cost other than
the defaults.
stp set port
<port-list>
port-cost
<num>
Specify the interval between hello
time
stp set bridging hello-time
<num>
Set the default of the forward delay
interval.
stp set bridging forward-delay
<num>
