user defined OUIs is 10.
Select the OUI and press Add to the lower table to complete the Auto Voice VLAN setting.
Note:
Voice VLAN has higher priority than any
oth
er features (including QoS). Therefore the
voice traffic will be operated according to the
Voice VLAN setting and not impacted by the QoS
feature.
Note: It is recommended
setting the highest
priority for Voice VLAN to guarantee the quality of
VoIP traffic.
VLAN > Voice VLAN > Voice VLAN Port Settings
The Voice VLAN Port Settings page allows users to automatically place the voice traffic from IP phone to an
assigned VLAN to enhance the VoIP service. With a higher priority and individual VLAN, the quality and the
security of VoIP traffic are guaranteed.
