CCNA 2.4.a: Access ports (data and voice) (FREE LAB!)


How to configure an access port for data and voice


Study Notes:

  • A data and voice access port is required when you have a computer connected to a VoIP phone at a desk
  • The switchport is configured with a voice vlan and a data vlan
  • This is called a Multi-VLAN Access Port (MVAP)
  • The VoIP phone has two different ports in the back and acts as a switch
  • The PC port is for the computer and it uses the access vlan configured on the switchport
  • The switch port on the back of the VoIP phone connects to the switch
  • The VoIP phone will use the voice vlan configured on the switch

    Fun lab.
    In the lab, the IP Phone is disabled because it is not powered on. The IP Phone must be powered on for the pings to work.
    1) Open the IP Phone (Physical tab)
    2) Select the power adapter in the lower right corner,
    3) Drag the power adapter to the back of the IP phone picture.
