If the source MAC address of a packet matches an OUI
address configured for the device, it is forwarded in the
voice VLAN; otherwise, it is dropped.
Forwarded or dropped depending on whether the port
allows packets of these VLANs to pass through
The port does not check the source MAC addresses of
inbound packets. All types of packets can be
transmitted in the voice VLAN.
