The packet is forwarded or
dropped based on whether the
receiving port is assigned to the
carried VLAN. The processing
method is irrelevant to the voice
VLAN mode (security or
normal).
The source MAC address of the
packet is not checked. All such
packets can be transmitted in
the voice VLAN.
The packet is forwarded or
