Voice Vlan Configuration; Oui Addresses - HP A6600 Configuration Manual

Voice VLAN configuration

This feature is available on only a SAP interface card working in bridge mode.
As voice communication technologies grow more mature, voice devices are more and more widely
deployed, especially on broadband networks, where voice traffic and data traffic often co-exist. Usually,
compared to data traffic, voice traffic is given a higher transmission priority for the purpose of reducing
transmission delay and packet loss.
A voice VLAN is configured especially for voice traffic. After assigning the ports connecting to voice
devices to a voice VLAN, the system automatically configures QoS parameters for voice traffic, improving
the transmission priority of voice traffic and ensuring voice quality.
Common voice devices include IP phones and IADs. Only IP phones are used in the voice VLAN
configuration examples in this chapter.

OUI addresses

A router determines whether a received packet is a voice packet by checking its source MAC address. A
packet whose source MAC address complies with the voice device's OUI address is regarded as voice
traffic.
Configure the OUI addresses of a device in advance or use the default OUI addresses.

In general, as the first 24 bits of a MAC address (in binary format), an OUI address is a globally unique
identifier assigned to a vendor by IEEE. However, OUI addresses mentioned in this document are
different from those in common sense. OUI addresses in this document are used by the system to
determine whether a received packet is a voice packet. They are the results of the AND operation of the
two parameters mac-address and oui-mask in the voice vlan mac-address command.
Remove the default OUI address of a device manually, and then add new ones manually.
