Usage guidelines
Configure the QoS priority settings for voice VLAN traffic on an interface before you enable voice VLAN
on the interface. If the configuration order is reversed, the priority settings will fail.
The voice vlan qos command and the voice vlan qos trust command can overwrite each other. When you
execute the two commands on a port multiple times, the most recent configuration takes effect.
Examples
# Configure interface GigabitEthernet 4/0/1 to modify the CoS value and the DSCP value marked for
voice VLAN packets into 5 and 45, respectively.
<Sysname> system-view
[Sysname] interface GigabitEthernet 4/0/1

Related commands
