undo voice vlan qos

View

Layer 2 Ethernet interface view

Default level

Parameters

Description

Use voice vlan qos trust to configure the 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 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 trust mode for voice VLAN traffic on an interface before enabling voice VLAN on the interface. If the configuration order is reversed, your priority trust setting will fail.

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

Related commands: voice vlan qos.
