• The Voice VLAN cannot be Smartport enabled.
• The Voice VLAN QoS decision has priority over any other QoS decision,
except for the Policy decision.
• A new VLAN ID can be configured for the Voice VLAN only if the current
Voice VLAN does not have candidate ports.
• The interface VLAN of a candidate port must be in General or Trunk mode.
• The Voice VLAN QoS is applied to candidate ports that have joined the
Voice VLAN, and to static ports.
• The voice flow is accepted if the MAC address can be learned by the
Forwarding Database (FDB). (If there is no free space in FDB, no action
occurs).
Voice VLAN Workflows
