Access and Trunk Port



When it comes to networking, there are two main types of ports that are used for communication: access ports and trunk ports. Access ports are used to connect end-user devices such as computers, printers, and phones to a local area network (LAN). Trunk ports are used to connect two switches together or to connect a switch to a router or other networking device.

Access ports are used to connect devices that are not part of the switch’s internal network. These ports are used to link computers and other devices to the local area network. Access ports are the endpoints of the network and are usually configured with the appropriate network settings. Generally, a switch will have multiple access ports, and each port can be assigned to a different VLAN. This allows the switch to route traffic from the different devices connected to it, based on the VLAN they are assigned to.

Trunk ports, on the other hand, are used to connect two switches together, or to connect a switch to a router, switch, or other network device. These ports are used to send and receive packets between two devices. They are configured with the appropriate settings for the type of traffic that will be sent and received. They also have the ability to be configured to carry multiple VLANs, which allows for traffic from multiple VLANs to be routed between the switches.

When configuring a switch, it is important to distinguish between access ports and trunk ports as they will be used for different purposes. Access ports are used to connect end-user devices while trunk ports are used to connect two switches together or to other network devices. Access ports are configured with the appropriate network settings while trunk ports are configured with the appropriate settings for the type of traffic it will carry.

In summary, access ports are used to connect end-user devices such as computers, printers, and phones to a local area network. Trunk ports are used to connect two switches together or to connect a switch to a router or other networking device. Access ports are configured with the appropriate network settings while trunk ports are configured with the appropriate settings for the type of traffic it will carry. It is important to properly configure access and trunk ports as they will be used for different purposes.
