Note:
If you enable storm control feature for the ingress rate limit-enabled port, ingress rate limit
feature will be disabled for this port.
11.3 Voice VLAN
Voice VLANs are configured specially for voice data stream. By configuring Voice VLANs and
adding the ports with voice devices attached to voice VLANs, you can perform QoS-related
configuration for voice data, ensuring the transmission priority of voice data stream and voice
quality.
OUI Address (Organizationally unique identifier address)
The switch can determine whether a received packet is a voice packet by checking its source
MAC address. If the source MAC address of a packet complies with the OUI addresses
configured by the system, the packet is determined as voice packet and transmitted in voice
VLAN.
An OUI address is a unique identifier assigned by IEEE (Institute of Electrical and Electronics
Engineers) to a device vendor. It comprises the first 24 bits of a MAC address. You can
recognize which vendor a device belongs to according to the OUI address. The following table
shows the OUI addresses of several manufacturers. The following OUI addresses are preset of
the switch by default.

Table 11-1 OUI addresses on the switch
Port Voice VLAN Mode
A voice VLAN can operate in two modes: automatic mode and manual mode.
Automatic Mode: In this mode, the switch automatically adds a port which receives voice
packets to voice VLAN and determines the priority of the packets through learning the source
MAC of the UNTAG packets sent from IP phone when it is powered on. The aging time of voice
VLAN can be configured on the switch. If the switch does not receive any voice packet on the
ingress port within the aging time, the switch will remove this port from voice VLAN. Voice ports
are automatically added into or removed from voice VLAN.
