Voice VLAN Overview
This section covers the following topics:
Dynamic Voice VLAN Modes
Auto Voice VLAN, Auto Smartports, CDP, and LLDP
Voice VLAN QoS
Voice VLAN Constraints
Voice VLAN Workflows
The following are typical voice deployment scenarios with appropriate configurations:
UC3xx/UC5xx hosted: All Cisco phones and VoIP endpoints support this deployment
model. For this model, the UC3xx/UC5xx, Cisco phones and VoIP endpoints reside in
the same voice VLAN. The voice VLAN of UC3xx/UC5xx defaults to VLAN 100.
Third-party IP PBX-hosted: Cisco SBTG CP-79xx, SPA5xx phones and SPA8800
endpoints support this deployment model. In this model, the VLAN used by the phones
is determined by the network configuration. There may or may not be separate voice
and data VLANs. The phones and VoIP endpoints register with an on-premise IP PBX.
IP Centrex/ITSP hosted: Cisco CP-79xx, SPA5xx phones and SPA8800 endpoints
support this deployment model. For this model, the VLAN used by the phones is
determined by the network configuration. There may or may not be separate voice and
data VLANs. The phones and VoIP endpoints register with an off-premise SIP proxy in
“the cloud”.
From a VLAN perspective, the above models operate in both VLAN-aware and VLAN-
unaware environments. In the VLAN-aware environment, the voice VLAN is one of the many
VLANs configured in an installation. The VLAN-unaware scenario is equivalent to a VLAN-
aware environment with only one VLAN.
The device always operates as a VLAN-aware switch.
