Voice Vlan Qos Trust - H3C S7500E Series Command Reference Manual

Configure the 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 settings will fail.
The voice vlan qos command and the voice vlan qos trust command can overwrite the other.
After you execute the two commands on a port multiple times, the one that was last executed
takes effect.
