NOTE:
A port can belong to only one voice VLAN at a time.
You cannot enable voice VLAN on a port where Link Aggregation Control Protocol (LACP) is enabled.
Configuring QoS priority settings for voice traffic on an
interface
In voice VLAN applications, you can improve the quality of voice traffic by configuring the appropriate
QoS priority settings, including the Class of Service (CoS) and Differentiated Services Code Point (DSCP)
values, for voice traffic. Voice traffic carries its own QoS priority settings. You can configure the device
either to modify or not to modify the QoS priority settings that the incoming voice traffic carries.
Follow these steps to configure QoS priority settings for voice traffic:
To do...
Enter system view
Enter interface view
Configure the interface to trust the
QoS priority settings in incoming
voice traffic, but not to modify the
CoS and DSCP values marked for
incoming traffic of the voice VLAN
Configure the interface to modify
the CoS and DSCP values marked
for incoming traffic of the voice
VLAN into specified values
NOTE:
Configure the QoS priority settings for voice traffic on an interface before you enable voice VLAN on the
interface. If the configuration order is reversed, your priority trust setting will fail.
