Recommended Voice Vlan Configuration Procedure - HP FlexNetwork NJ5000 User Manual

In a safe network, you can configure the voice VLANs to operate in normal mode, reducing the
consumption of system resources due to source MAC addresses checking.
Hewlett Packard Enterprise recommends not transmitting both voice packets and non-voice packets
in a voice VLAN. If you have to, first make sure that the voice VLAN security mode is disabled.

procedure
Before configuring the voice VLAN, you must create the VLAN and configure the link type of each
port to be assigned to the VLAN. Because VLAN 1 is the system-default VLAN, you do not need to
create it; however, you cannot configure it as the voice VLAN. For information about port link types,

Configure the voice VLAN assignment mode of a port as automatic
and enable the voice VLAN function on the port.
By default, the voice VLAN assignment mode of a port is automatic,
and the voice VLAN function is disabled on a port.

Packet processing mode
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.
If the packet is a voice packet
does not carry the voice VLAN tag
or PVID tag, the packet is
dropped. Otherwise, the packet is
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.
