Components of voice VLAN operation

  • Voice VLAN: Configure one or more voice VLANs on the switch. Some reasons for having multiple voice VLANs include:

    • Employing telephones with different VLAN requirements

    • Better control of bandwidth usage

    • Segregating telephone groups used for different, exclusive purposes

    Where multiple voice VLANs exist on the switch, you can use routing to communicate between telephones on different voice VLANs.

  • Tagged/Untagged VLAN Membership: If the appliances using a voice VLAN transmit tagged VLAN packets, then configure the member ports as tagged members of the VLAN. Otherwise, configure the ports as untagged members.
