Configuration guidelines

When you configure the voice VLAN function, follow these guidelines:
• To remove a VLAN functioning as a voice VLAN, disable its voice VLAN function first.
In automatic voice VLAN assignment mode, a hybrid port can process only tagged voice traffic.
•
However, the protocol-based VLAN function requires hybrid ports to process untagged traffic. If a
VLAN is configured as the voice VLAN and a protocol-based VLAN at the same time, the
protocol-based VLAN cannot be associated with the port.
Only one VLAN is supported and only an existing static VLAN can be configured as the voice
•
VLAN.
Do not enable the voice VLAN function on a link aggregation group member port.
•
After you assign a port operating in manual voice VLAN assignment mode to the voice VLAN, the
•
voice VLAN takes effect.
Recommended voice VLAN configuration
procedure
Before you configure 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, see
"Managing ports."

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.
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.
Forwarded or dropped depending
on whether the port allows packets
of these VLANs to pass through.
