9.3 Voice VLAN
Voice VLANs are configured specifically for Voice Data. By configuring Voice VLANs and
adding the Ports with Voice devices attached, you can perform QoS-Related filtering
for Voice Data, ensuring the Priority of Voice Data Stream and Voice quality.
OUI (Organizationally Unique Identifier)
The Switch can determine whether a received packet is a Voice packet by checking
its Source MAC Address. If the Source MAC Address of packets complies with an OUI
configured in the system, the packets are identified as Voice packets and transmitted in
Voice VLAN.
An OUI 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
identify which vendor a device belongs to using the OUI. The following table shows the
OUIs of several manufacturers. The following OUIs are preset in the Switch by default.
