Voice Vlan Commands - D-Link DWS-4000 Series Cli Command Reference

V VLAN C
OICE
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch ports to carry voice traffic with
defined priority so as 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.
voice vlan (Global Config)
Use this command to enable the Voice VLAN capability on the switch.
Default disabled
Format
voice vlan
Mode Global Config
no voice vlan (Global Config)
Use this command to disable the Voice VLAN capability on the switch.
Format
no voice vlan
Mode Global Config
voice vlan (Interface Config)
Use this command to enable the Voice VLAN capability on the interface.
Default disabled
Format
voice vlan {vlanid <id> | dot1p <priority> | none | untagged}
Mode Interface Config
You can configure Voice VLAN in one of four different ways:
Parameter Description
vlan-id Configure the IP phone to forward all voice traffic through the specified VLAN. Valid VLAN ID's are from
1 to 4094 (the max supported by the platform).
dot1p Configure the IP phone to use 802.1p priority tagging for voice traffic and to use the default native
VLAN (VLAN 0) to carry all traffic. Valid <priority> range is 0 to 7.
none Allow the IP phone to use its own configuration to send untagged voice traffic.
untagged Configure the phone to send untagged voice traffic.
