Operating rules for voice VLANs

  • You must statically configure voice VLANs. GVRP and dynamic VLANs do not support voice VLAN operation.

  • Configure all ports in a voice VLAN as tagged members of the VLAN. This ensures retention of the QoS (Quality of Service) priority included in voice VLAN traffic moving through your network.

  • If a telephone connected to a voice VLAN includes a data port used for connecting other networked devices (such as PCs) to the network, then you must configure the port as a tagged member of the voice VLAN and a tagged or untagged member of the data VLAN you want the other networked device to use.
