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.
Examples
# Configure interface GigabitEthernet 2/0/1 to modify the CoS value and the DSCP value marked for
voice VLAN packets into 5 and 45 respectively.

Description
Use the voice vlan qos trust command to configure the current interface to trust the priority settings
carried in incoming voice traffic. With this command configured, an interface keeps the CoS and DSCP
values marked for incoming voice traffic unchanged.
Use the undo voice vlan qos command to restore the default.
By default, an interface modifies the CoS value and the DSCP value marked for voice VLAN traffic into
6 and 46 respectively.
Related commands: voice vlan qos.
