2.13 Voice VLAN

2.13.1 Introduction

With increasing growth of voice technologies, voice devices are more and more widely used,
especially in broadband residential communities. The network usually transmits voice traffic
and data traffic concurrently, but voice traffic requires a higher priority than data traffic in
transmission to avoid delay and packet loss.
A voice VLAN is especially partitioned for voice traffic of users. By partitioning voice
VLANs and add interfaces of the voice device to voice VLANs, you can configure QoS of
voice traffic to increase the priority of transmitting voice traffic and guarantee call quality.
Compared with other methods for managing voice traffic, the voice VLAN has the following
advantages:

Easy configuration: after you configure the voice device in global configuration mode
and interface configuration mode and enable the voice VLAN, the voice device can
classify and process voice traffic.
Easy maintenance: you can modify rules (voice VLAN OUI address) for matching voice
traffic in global configuration mode. When a new IP voice device joins the network, its
interfaces can rapidly identify voice traffic by updated matching rules.
