Configuring a voice VLAN

Configuration prerequisites

Before you configure a voice VLAN, complete the following tasks:
Create a VLAN.
•
Configure QoS priority settings for voice VLAN traffic on an interface before enabling voice VLAN
•
on the interface.
If the configuration order is reversed, your priority configuration will fail. For more information, see
"Configuring QoS priority settings for voice traffic on an
Configure the voice VLAN assignment mode.

and "Configuring a port to operate in manual voice VLAN assignment
A port can belong to only one voice VLAN at a time.
Voice VLAN cannot be enabled on a port with LACP enabled.
Configuring QoS priority settings for voice traffic on an
interface
In voice VLAN applications, improve the quality of voice traffic by configuring the appropriate QoS
priority settings, including the CoS and DSCP values, for voice traffic. Voice traffic carries its own QoS
priority settings. Configure the router either to modify or not to modify the QoS priority settings carried by
incoming voice traffic.

If the source MAC address of a packet matches an OUI
address configured for the router, 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. In this way, both voice traffic and non-voice
traffic can be transmitted in the voice VLAN.
