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. The voice VLAN modes of different ports are independent of one another. To make voice VLAN take effect on a port which is enabled with voice VLAN and operates in manual voice VLAN assignment mode, assign the port to the voice VLAN manually. Examples # Configure GigabitEthernet 1/0/1 to operate in manual voice VLAN assignment mode. system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] undo voice vlan mode auto voice vlan qos Syntax voice vlan qos cos-value dscp-value View undo voice vlan qos Layer 2 Ethernet interface view Default level 2: System level Parameters cos-value: Sets the CoS precedence value for voice VLAN traffic. The default value is 6. dscp-value: Sets the DSCP value for voice VLAN traffic. The default value is 46. 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. Examples # Configure interface GigabitEthernet 1/0/1 to modify the CoS value and the DSCP value marked for voice VLAN packets into 5 and 45, respectively. 179
