Voice VLAN Commands
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch
ports to carry voice traffic with defined priority to enable separation of voice and data traffic
coming onto the port. The benefits of using Voice VLAN is to ensure that the sound quality of
an IP phone could be safeguarded from deteriorating when the data traffic on the port is high.
ports to carry voice traffic with defined priority to enable separation of voice and data traffic
coming onto the port. The benefits of using Voice VLAN is to ensure that the sound quality of
an IP phone could be safeguarded from deteriorating when the data traffic on the port is high.
Also the inherent isolation provided by VLANs ensures that inter-VLAN traffic is under
management control and that network- attached clients cannot initiate a direct attack on
voice components. QoS-based on IEEE 802.1P Class of Service (CoS) uses classification
and scheduling to sent network traffic from the switch in a predictable manner. The system
uses the source MAC of the traffic traveling through the port to identify the IP phone data
flow.

disabled. The default value for this field is disabled.
EtherType
A 2-byte hex EtherType to be used as the first 16 bits of the DVLAN tunnel. There are
three different EtherType tags. The first is 802.1Q, which represents the commonly used
value of 0x8100. The second is vMAN, which represents the commonly used value of
0x88A8. If EtherType is not one of these two values, it is a custom tunnel value,
representing any value in the range of 0–65535.
