As the size of data center becomes larger and larger, cable density increases, too. To simplify the cabling, many data center managers prefer network switch with high density ports. The above 48 port gigabit SFP switch with 10GE SFP+ uplinks is a suitable choice for high density cabling.
When it comes to network switch, we usually ask about the port type on the switch and the number of port, such as twenty-four 10/100/1000 Mbps ports and four SFP+ ports. If you have used managed switch in your network deployment, you must have heard about uplink port or normal port. How much do you know about them? Is there any difference between them? This article will guide you to learn about uplink port vs. normal port on switch.
Uplink Port Vs. Normal Port: Connect to Different Devices
The uplink port on switch is used to connect a device or smaller local network to a larger network, or connect to the next “higher” device in the topology. For example, edge switch connects “up” to distribution layer managed switch. Also in computer network, hub, unmanaged switch and router typically designate one Ethernet port as the uplink port. And it may be labeled WAN or Internet instead of uplink. This type of port simplify connects different types of Ethernet devices to each other, such as when linking a local home network to a modem and the Internet. While normal port on switch is used to connect end user PC or server and all. In most cases, uplink ports have more bandwidth as compared to normal ports as they aggregate traffic between different layers.
Uplink Port Vs. Normal Port: Connect to Different Cables
Each Ethernet interface has two transmit pins and two receive pins. To achieve the link connection, the transmit pins at one end of network cable have to be connected to the receive pins at the other end. An uplink port does not crossover the transmit and receive pins, but a regular port does. Therefore, when two network switches are connected together with a straight-through cable, then one end must be uplink port and one end must be normal port. If a crossover cable is used to connect them, then the ports at both ends must be the same kind of port. Here is a figure for you to have a better understanding of this.
Uplink Port Vs. Normal Port: Additional Information about Shared Port and Dual-purposed Port
Some older network equipment specially configured a normal port next to the uplink port and linked the two together as a pair. Specifically, the hardware logic of these products supported connections to either the uplink port, or the normal shared port, but not both. Connecting devices to both ports of a shared port device stops the unit from functioning properly. Nowadays, many network equipment offer a dual-purpose port which can function either as an uplink or a normal port depending on the type of device connected to it.
In fact, uplink port can serve as normal port. Therefore, there are no big differences between them. The only difference is that uplink port is connected to higher layer network device to aggregate the bandwidth and must be connected to the normal port on another network device. I hope after reading this article, you can be clear on uplink port vs. normal port on switch.
Network switch, a box-shaped device, plays an important role in a network deployment. To achieve high network performance, a suitable switch is required. There are smart managed switch and unmanaged switch on the market. How much do you know about them? Smart managed switch vs. unmanaged switch, which one should you choose for your network deployment? Keep reading, and you will find the answer.
Smart Switch Vs. Managed Switch
If you look through the official website of several vendors, you may find that some offer smart switch, the others provide managed switch. Smart switch vs. managed switch, what’s the different between them? Smart switch has some features that managed switch has, but are more limited. Besides, smart switch is cheaper than managed switch. So, it’s a cost-effective alternative to managed switch. In fact, “smart switch” and “managed switch” are terms invented by vendors. And the exact meaning may vary from vendor to vendor. To some extent, smart switch and managed switch are virtually the same. In the following part, I combine them as smart managed switch for easy reading.
Smart Managed Switch Vs. Unmanaged Switch
As smart managed switch and unmanaged switch have different features, they are used in different applications.
Smart managed switch offers features like QoS (Quality of Service), Simple Network Management Protocol (SNMP), command line interface (CLI), Rapid Spanning Tree Protocol (RSTP), redundancy capability, VLANs, LACP and so on. The greatest advantage of smart managed switch is that you can change the configuration of the switch to satisfy your specific networking needs. Smart managed switch is especially suitable for enterprises that need to manage and troubleshoot their network remotely and securely, allowing network managers to monitor and control the traffic to achieve optimal network performance and reliability. The following figure shows FS S5800-8TF12S managed switch which provides high port density with 8-port 1GbE RJ45 and 8-port 1GbE SFP combo and 12-port 10GbE uplink in a compact 1RU form factor.
Unmanaged switch is basic plug-and-play switch with no remote configuration, management, or monitoring options. It allows Ethernet devices to communicate with one another (such as a PC or network printer) by providing a connection to the network and passing on information to where it needs to go. Therefore, unmanaged switch is usually used to extend the number of Ethernet ports. Unmanaged switch can be desktop or rack mounted. It is less expensive than smart managed switch and is suitable for home use, SOHO and small businesses.
Which One to Choose?
From the above content, we can conclude that smart managed switch vs. unmanaged switch, the biggest difference between them is the configuration feature. As for which one to choose, it really depends on your need. If you just want to set up a home network or add more Ethernet ports, unmanaged switch is good enough. If you need configuration options like VLAN and QoS, you will have to use smart managed switch.
