How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

DETAILED STEPS

To return to the default path cost, use the no bridge-group bridge-group path-cost cost command in

interface configuration mode.

Adjusting BPDU Intervals

You can adjust BPDU intervals as described in these sections:

• Adjusting the Interval between Hello BPDUs, page 60

• Changing the Forward-Delay Interval, page 61

• Changing the Maximum-Idle Interval, page 62

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 its individual configuration.

Adjusting the Interval between Hello BPDUs

Beginning in privileged EXEC mode, follow these step to adjust the interval between hello BPDUs.

SUMMARY STEPS

1. configure terminal

Command Purpose

Step 1

configure terminal

Example:

Router#configure terminal

Enters global configuration mode.

Step 2

interface type 0/slot/port

Example:

Router(config)#interface

gigabitethernet 0/1/2

Enters interface configuration mode, and specifies the interface to set

the path cost.

Step 3

bridge-group bridge-group path-cost

cost

Example:

Router(config-if)#bridge-group 1

path-cost 5

Assigns 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.

Step 4

end

Example:

Router(config-if)#end

Returns to privileged EXEC mode.
