A user may connect a computer to the switch’s console port and then configure the switch using the computer’s interface. Most network switches also have a console port that controls the operation of the switch itself. Both user devices and network devices can be connected through a hybrid port. It can manage both tagged and untagged frames, and it can receive data from more than one VLAN.
A hybrid port can function like both an access port and a trunk port.To do so, a trunk port recognizes frame tags that specify the intended destination for the data. On a complex network with multiple VLANs, a trunk port manages data transfer to and from those virtual networks. A trunk port usually connects to another switch, and it’s able to interact with several VLANs.Because data can only go back and forth on the designated VLAN, an access port handles untagged Ethernet frames. An access port connects a network host to a single VLAN and manages data traffic for that virtual network.One port is designated for the cable that connects the switch to the router, so the number of connections a switch accepts is one less than the number of ports. Each type of port has a unique function, and a standard Ethernet interface can function as any of these ports. In this type of network, there are three basic types of switch ports: access, trunk, and hybrid. Network switches are frequently used to create and manage VLANs. A switch port is a rectangular physical opening that accepts a data cable.
