Configuring the Cisco Gigabit EtherSwitch EHWIC
OL-23155-01
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, the show running command does 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 Gi0/1/5
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 Gi0/1/2 vlan 3
Router(config)#end
