Don JohnstonInstructorCommented:
VLAN 0 is an invalid VLAN number.  Basically it means that the port is not configured for any VLAN.
SYN ACKSnr Analyst Author Commented:
Ok what about traffic? Port is tagged with say vlan 20 and 10 and I guess all traffic with end up on default vlan?
Don JohnstonInstructorCommented:
Tagged traffic should still flow through the port.  It just won't have a native VLAN.
