Switch(config-if)#switchport pvid 20
Switch(config-if)#exit
Switch(config)#interface fastEthernet 1/0/3
Switch(config-if)#switchport general allowed vlan 30 untagged
Switch(config-if)#switchport pvid 30
Switch(config-if)#exit
Switch(config)#interface fastEthernet 1/0/4
Switch(config-if)#switchport general allowed vlan 40 tagged

3)  Check whether port1/0/1-3 only belong to VLAN 10, VLAN 20 and VLAN 30 
respectively. If not, delete them from the other VLANs. By default, all ports are in VLAN 1, 
so you need to delete them from VLAN 1.
