Example:
! The first four ports (e 0/0/1 – e0/0/4）connect to different server. These four servers
should be isolated. And the servers belong to VLAN 10，VLAN 20，VLAN 30 and VLAN 40
Switch(config)#vlan 10
Switch(config-if-vlan)#switchport ethernet 0/0/1
Add VLAN port successfully.
Switch(config-if-vlan)#vlan 20
Switch(config-if-vlan)#switchport ethernet 0/0/2
Add VLAN port successfully.
Switch(config-if-vlan)#vlan 30
Switch(config-if-vlan)#switchport ethernet 0/0/3
Add VLAN port successfully.
Switch(config-if-vlan)#vlan 40
Switch(config-if-vlan)#switchport ethernet 0/0/4
Add VLAN port successfully.
Switch(config-if-vlan)#interface ethernet 0/0/1
Switch(config-if-ethernet-0/0/1)#switchport default vlan 10
Switch(config-if-ethernet-0/0/1)#interface ethernet 0/0/2
