Simple question: Does the physical interface need an IP when all I want to do is create and use multiple VLANs on sub-interfaces? Those VLAN interfaces will have valid addresses but I'm not sure I need (or want) an address on the physical interface. 0.0.0.0/0.0.0.0 is fine with me...or am I missing something?

Thanks in advance!

You don't need to touch. But I would remove all "allowaccess" and change the mode to static if it's DHCP, otherwise it would keep broadcasting non-tagged DHCP requests.
