Cisco HWIC-4ESW and HWIC-D-9ESW EtherSwitch Interface Cards

Configuration Examples for EtherSwitch HWICs

Cisco IOS Release 12.3(8)T4

OL-6454-01

Forward-Delay Time for a VLAN Example

The following example shows the forward delay time for VLAN 20 being configured to 21 seconds:

Router# configure terminal

Router(config)# spanning-tree vlan 20 forward-time 21

Router(config)# end

Router#

Maximum Aging Time for a VLAN Example

The following example configures the maximum aging time for VLAN 20 to 36 seconds:

Router# configure terminal

Router(config)# spanning-tree vlan 20 max-age 36

Router(config)# end

Router#

Spanning Tree Examples

The following example shows spanning tree being enabled on VLAN 20:

Router# configure terminal

Router(config)# spanning-tree vlan 20

Router(config)# end

Router#

Note Because spanning tree is enabled by default, issuing a show running command to view the resulting

configuration will not display the command you entered to enable spanning tree.

The following example shows spanning tree being disabled on VLAN 20:

Router# configure terminal

Router(config)# no spanning-tree vlan 20

Router(config)# end

Router#

Spanning Tree Root Example

The following example shows the switch being configured as the root bridge for VLAN 10, with a

network diameter of 4:

Router# configure terminal

Router(config)# spanning-tree vlan 10 root primary diameter 4

Router(config)# exit

Router#

MAC Table Manipulation: Example

The following example shows a static entry being configured in the MAC address table:

Router(config)# mac-address-table static beef.beef.beef int fa0/1/5

Router(config)# end

The following example shows port security being configured in the MAC address table.

Router(config)# mac-address-table secure 0000.1111.2222 fa0/1/2 vlan 3

Router(config)# end
