Configuration Examples for the 16- and 36-Port Ethernet Switch Module
BackboneFast Example
The following example shows BackboneFast being enabled on the Ethernet switch module:
Router# configure terminal
Router(config)# spanning-tree backbonefast
Router(config)# end
Router#
Spanning Tree Examples
The following example shows spanning tree being enabled on VLAN 200:
Router# configure terminal
Router(config)# spanning-tree vlan 200
Router(config)# end
Router#
Because spanning tree is enabled by default, issuing a show running command to view the resulting
Note
configuration will not display the command you entered to enable spanning tree.
The following example shows spanning tree being disabled on VLAN 200:
Router# configure terminal
Router(config)# no spanning-tree vlan 200
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 Examples
The following example shows a dynamic entry being configured in the MAC address table:
Router# configure terminal
Router (config)# mac-address-table dynamic 6.6.6 fastEthernet 2/13 vlan 1
Router (config)# end
The following example shows a static entry being configured in the MAC address table:
Router(config)# mac-address-table static beef.beef.beef int fa0/11 vlan 1
Router(config)# end
Cisco Discovery Protocol (CDP) Example
The following example shows CDP counter configuration being configured on the NM-16ESW:
Router# clear cdp counters
