Description
Use voice vlan mode auto to configure the port to operate in automatic voice VLAN assignment
mode.
Use undo voice vlan mode auto to configure the port to operate in manual voice VLAN assignment
mode.
By default, a port operates in automatic voice VLAN assignment mode.
For a port that is enabled with voice VLAN and operating in manual mode, you must manually assign
the port to the voice VLAN to make the voice VLAN take effect.

Description
Use voice vlan qos to configure the interface to modify the CoS and DSCP values marked for
incoming traffic of the voice VLAN into specified values.
Use undo voice vlan qos 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.
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 one takes effect.
Related commands: voice vlan qos trust.
