Switch(config-if)#switchport access vlan 10
Switch(config-if)#switchport voice vlan 101
Switch(config-if)#switchport port-security
Switch(config-if)#switchport port-security maximum 3
Switch(config-if)#switchport port-security maximum 2 vlan access
Switch(config-if)#switchport port-security maximum 1 vlan voice
Switch(config-if)#switchport port-security violation shutdown vlan
Switch(config-if)#switchport port-security mac-address 0000.0203.0405 vlan
