Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

DETAILED STEPS

To return to the default setting, use the no bridge bridge-group max-age command in global

configuration mode.

Disabling the Spanning Tree on an Interface

When a loop-free path exists between any two switched subnetworks, you can prevent BPDUs generated

in one switching subnetwork from impacting devices in the other switching subnetwork and still permit

switching throughout the network as a whole. For example, when switched LAN subnetworks are

separated by a WAN, BPDUs can be prevented from traveling across the WAN link.

Beginning in privileged EXEC mode, follow these steps to disable spanning tree on an interface.

SUMMARY STEPS

1. configure terminal

2. interface type 0/slot/port

3. bridge-group bridge-group spanning-disabled

4. end

Command Purpose

Step 1

configure terminal

Example:

Router#configure terminal

Enters global configuration mode.

Step 2

bridge bridge-group max-age seconds

Example:

Router(config)#bridge 1 max-age 50

Specifies the interval the switch waits to hear BPDUs from the root

switch.

• For bridge-group, specify the bridge group number. The range is 1

to 255.

• For seconds, enter a number from 10 to 200. The default is 30.

Step 3

end

Example:

Router(config)#end

Returns to privileged EXEC mode.
