Voice VLAN
Configure the Voice VLAN settings for ports that carry traffic from IP phones. The voice VLAN
feature can help ensure that the sound quality of an IP phone is safeguarded from
deteriorating when the data traffic on the port is high.
The following are two operational modes for IP phones:
•
IP phones are configured with VLAN mode enabled, ensuring that the phone uses tagged
packets for all communications.
•
IP phones are configured with VLAN mode disabled, ensuring that the phone uses
untagged packets for all communications. The phone uses untagged packets while
retrieving the initial IP address through DHCP. The phone eventually uses the voice
VLAN and commences sending tagged packets.
From the VLAN menu, you can access the features described in the following sections:
•
Voice VLAN Properties
•
Voice VLAN Port Setting
•
Voice VLAN OUI

remarks on the selected port.
6.
In the Voice VLAN Aging Time field, specify the amount of time after the last IP phone’s
OUI is aged out for a specific port.
