What is a
Switch
Port
?
How to select and use it? This article attempts to make an overview of Switch Port.
Introduction:
As the name suggests, a switch port is the port of a switch. Before answering the question,
what is a
Switch
Port,
we might as well explain what a switch is.
The switch, also named as the network switch, is the networking equipment that links devices on a computer network by receiving and
forwarding
data to the destination device using packet switching. The switch port is the physical opening on the switch in which the data wire can be plugged. This article describes the concept, types, features, and configuration of switch ports to illustrate
what is a switch port
exactly.
What is a Switch Port
?
The switch port on a network switch is the actual hole where a data cable can be inserted.
Switch
ports often have a V-shaped tip on the top or bottom and are rectangular on three sides. Connecting various devices to the ports on a network switch enables them to interact with each other through data transfer within the switch. Most networking devices connect to the internet, enabling the devices to acquire
internet access
through the switch ports.
A port is a crucial part of networking hardware like residential
Ethernet
switches or commercial network switches. Although most switches have physically identical ports, you might be able to customize them for different purposes. The number of ports and their configurations depend on the switch's intended use.
How many
Switch
Ports are on a Switch?
There are numerous ports on a switch, varying according to the device’s function. Switches can have 5-port to 52-port configurations. Fixed-configuration switches typically come with five, eight, ten, sixteen, twenty-four, eighteen, forty-eight, or fifty-two ports. You should think about the number of users your network can accommodate when determining how many ports you'
ll
need. The more users in your network, the more ports you'll need. Besides the number of ports you require, this will also require understanding more about the various kinds of ports and how they operate.
Types and Applications of Switch Port
The switch ports can be classified into a wide range of sorts in accordance with many terms. Generally speaking, network switches are frequently used to create and manage VLANs. In this kind of network, there are three primary types of switch ports: access port, trunk port, and hybrid port. A standard
Ethernet
interface can act as any of these ports, each of which has a specific function.
1. Access Port.
An access port is a connection on a switch that transfers data to and from a specific
VLAN
. It is used to link servers, workplaces, and other end devices with the network. Receiving data from and transmitting the data to end devices are its main functions. It sends and receives
Ethernet
frames in untagged form from access VLAN. In an Ethernet network, an access port can only belong to the access VLAN and will drop any transmissions that are not assigned to it.
2. Trunk Port.
A trunk port is known as a switch connection that allows for communication among multiple VLANs.
Switch
ports of this kind connect switches to other switches, routers, and servers that are accessible through the trunk link. A trunk port, which is frequently connected to another switch, can communicate with many VLANs. Frames are marked with unique identifying tags when they move between switches so that they can be forwarded to their designated VLANs. It can simultaneously handle traffic for many VLANs.
3. Hybrid Port.
A hybrid port is a link on a switch that enables data transfer to and from one or more VLANs. It supports both tagged and untagged frames from VLANs on access and trunk ports and can receive frames from one or more VLANs at the same time. User devices, such as laptops, and network devices, like switches, are connected using this sort of switch port.
How to Configure a
Switch
Port?
Smart switches and managed switches both support configuration. Depending on the device, you might be able to enable or disable particular ports, restrict
bandwidth
, implement port mirroring, designate access and trunk ports, or establish a
VLAN
. Command-line interface and the Simple Network Management Protocol are useful means to set switch ports. Your switch may include a web-based interface that you may use to configure it. Clear setup instructions should be provided by the manufacturer.
Conclusion
This article answers the question
"What is a
Switch
Port"
by giving an overall explanation of its concept, types, features as well as configurations. As mentioned above, a switch port is an actual hole on a network switch on a network switch where a data cable can be inserted. Figuring out the principles of switch ports enables you to select more suitable
Ethernet
switches for your network needs. Hope this article will give you some inspiration on understanding and choosing switch ports.
