SW1(config)#int range Fa0/13 - 21
SW1(config-if-range)#switchport trunk native vlan 146
SW2(config)#int range Fa0/13 - 21
SW2(config-if-range)#switchport trunk native vlan 146
SW3(config)#int range Fa0/13 - 21
SW3(config-if-range)#switchport trunk native vlan 146
SW4(config)#int range Fa0/13 - 21
SW4(config-if-range)#switchport trunk native vlan 146
