7.2 Voice VLAN
Traditionally, ACL (Access Control List) will be applied to distinguish Voice Data and
QoS (Quality of Service) will be used to ensure transmission quality, thus enhancing the
priority. In order to simplify user configuration and facilitate voice flow management, Voice
VLAN emerges. Enabled interface judges whether it is Voice Data flow or not according
to the source MAC address field accessing the interface data flow. The message in the
source MAC address is the Voice Data flow, which confirms to the OUI (Organizationally
Unique Identifier) of the voice devices that are configured by the system. The interfaces
receiving Voice Data flow will automatically transmit to Voice VLAN, thus simplifying user
configuration and Voice Data management.
OUI of Voice VLAN
OUI represents a MAC address field. Its address can be calculated based on the
48-bit MAC address and the corresponding bit of mask. The number of bits of ingress
MAC address and matching OUI is determined by the length of the all “1”-bit in the mask.
For example, if the MAC address is 1-1-1 and the mask is FFFF-FF00–0000, the result of
execution and calculation of MAC address and corresponding mask, namely OUI, will be
0001–0000–0000.
If the first 24 bits of the ingress MAC address are matched with those of OUI, the
enabled Voice VLAN interface identifies the data flow and the ingress device as the Voice
Data flow and voice device respectively.
Voice VLAN is divided for user Voice Data flow. Voice VLANs are created to connect
the interfaces linked with voice devices to transmit the Voice Data inside in a centralized
way.
Voice Data and non-Voice Data often exist in the same network. Voice Data needs
a higher priority than other business data during transmission to reduce the possible delay
and packet loss.
