ccna vs ccnp.Voice VLANs are more unique in that they are associated with ports to which VoIP phones are connected. Some VoIP phones are connected to a multi-port switch, allowing other devices to connect to the phone through that switch. In this case, the phone may tag the frames to indicate which device (phone or computer) the traffic is sent from, allowing the switch to handle the traffic properly.Authentication Objective 12.0212.2 MLAN ConnectivityTo handle VLANs, the switch supports two types of ports: access ports and trunk ports. When configuring the switch, you need to know which type the interface should be, and thus configure it accordingly. You will see that the configuration process is different for each interface type. This section discusses both types of connections.12.2.1 Access Link ConnectionAn access link connection is a connection to a device that uses a standardized Ethernet NIC and can only understand standardized Ethernet frames. An access link connection can only belong to one VLAN (except for voice VLAN ports), which means that all devices connected to that port belong to the same broadcast domain.An access link connection is a connection between a switch and a device that uses a regular Ethernet NIC, which carries Ethernetframes (untagged). An incoming link connection usually belongs to only one VLANoFor example, if 10 users are connected to a hub that is connected to the switch's access link interface, all of those users would belong to the VLAN associated with that switch port o To have five of those users belong to one VLAN and the other five belong to another VLAN, you would need to purchase another hub and connect each hub to a different switch port . Then, the correct VLAN identifier needs to be configured on the switch for both ports.1222 Trunk Connection
