Access Ports (Data and Voice) in CCNA

Pre-requisites:- Access ports, ping

Voice and data access ports are required when an end host is connected to a VoIP device. These are known as Multi VLAN Access Ports(MVAP). Using this allows both the PC and Phone to communicate using a single switch port which would otherwise require 2 ports.

👁 Access ports (Data and Voice) in CCNA

An access port can be made MVAP using the command:

interface <interface>
switchport mode access
switchport access vlan <vlan>
switchport voice vlan <vlan>

Configuring MVAP:

Consider a topology:

👁 Configuring MVAP

A point to note is that IP phones are by default turned off you need to turn them on by adding power supply in the physical section.

Configuring Switch Physical Interfaces:

interface FastEthernet0/1
switchport mode access
switchport voice vlan 20
interface FastEthernet0/2
switchport mode access

Now PC4 and PC3 can now communicate while using only using 2 switch ports.
