So let me see if I understand this correctly. Say I have a trunk link between Switch A and Switch B that carries VLAN 10 & 11. Normally when I hook a client up to a port on switch A I assign it to a vlan (either 10 or 11). Now if I didnt put that port in either VLAN 10 or 11 and that users packet crosses the trunk link would it be assigned to the "native vlan". Although, if I didnt assign the port a vlan wouldn't that port still be in its native vlan of the switch which would be vlan 1. I am having a hard time seeing the use for this command, because every switch port on these switches would be in some vlan either deafult or assigned manually. Thanks Amy.
