In this comparison we are going to talk about two switch models, the D-Link DGS-108 and the DGS-108GL, because the “105” versions are exactly the same, but in their version with 5 ports instead of 8 ports, the The rest of the characteristics are exactly the same as the DGS-108 or DGS-108GL versions, the differences will be found in that they are different families.
Before we start talking about the differences between the two switches, let’s talk about the characteristics that are common to the two. These switches are non-manageable equipment, we do not have any L2 or L2 + management option, they are fully Plug & Play, we will only have to connect the different equipment to the switch via Ethernet network cable, and all the equipment would already be interconnected and connected to the network. local and Internet.
Both switches have 8 Gigabit Ethernet ports for LAN, with support for 10/100 / 100Mbps speed, have auto-negotiation, auto-MDI / MDIX and they also have flow control with 802.3x standard, QoS based on the 802.1p standard, but in this case, as it is an unmanageable switch, we do not have the possibility to configure these priority queues as we want. Other very important characteristics are that we have a metal casing to dissipate the heat generated by the internal components, we do not have a fan for active cooling, therefore, we have a fully passive cooling and without any fan noise. The metal housing together with the fact that we have the 802.3az energy saving standard, make these switches absolutely not hot, ideal for a home environment.
The DGS-108 and DGS-108GL have a MAC address table of up to 4K entries, and support for Jumbo Frames, or also known as jumbo frames, with a length of up to 9216 bytes. Thanks to the Jumbo Frames, we will be able to squeeze the maximum speed of the Gigabit Ethernet ports that these switches have, in this way, we can achieve speeds of up to 118MB / s speed when transferring very large files.
As you can see, the main characteristics of both switches are exactly the same, but we find important differences that we will detail.
Differences between DGS-108 and DGS-108GL
On a physical level the differences are clear, not only do they have a slightly different design, but their size and weight are also different:
- The DGS-108 measures 162mm x 102mm x 28mm
- The DGS-108GL measures 140mm x 67mm x 26mm
As you can see, the DGS-108GL is clearly smaller, both in width and depth, making it ideal to place it inside the PAU at the entrance of the house and provide connectivity to all network sockets. Another difference between both switches is the weight, the DGS-108 has a weight of 415 grams, and the DGS-108GL model weighs 240 grams, almost half. It is clear that the DGS-108GL is not only smaller but also less heavy.
The most important difference between both switches is that DGS-108 does support IGMP Snooping, something that the DGS-108GL model does not support it, nor will it ever. IGMP Snooping is a protocol that allows us to efficiently manage multicast traffic throughout the network, preventing the switch from forwarding multicast traffic through all its ports to the different computers, in such a way that only the computer requesting the traffic , is provided to you. If in a network we have IPTV services such as Movistar, which makes use of multicast traffic, if we install a switch without IGMP Snooping the network will collapse and be blocked sooner or later, otherwise, if we have a switch with this IGMP function Snooping, everything will work perfectly without any problems.
Finally, we also have the difference between the two switches in the price, the DGS-108 model is worth about 27 euros approximately, and the DGS-108GL model is somewhat cheaper, about 24 euros approximately. We have a difference of about 3-5 euros depending on whether or not it is on promotion.
Which of the two models should I buy?
The decision to buy the DGS-105/108 or the DGS-105GL / 108GL model is clear, it depends on whether or not you need the IGMP Snooping protocol on your local network.
- If you have IPTV services like Movistar’s, or are going to have it in the future, then you must buy the DGS-108.
- If you do not have IPTV services, and do not plan to have it in the future, then you can buy the DGS-108GL, you will save money and also space.
If you do not mind spending 3-5 euros more, our recommendation is that you buy the DGS-105/108, because you will have IGMP Snooping in case in the future you decide to hire IPTV services that make use of multicast traffic, if you are very clear that you are never going to contract these services, then you can buy the DGS-105GL / 108GL model that will provide you with exactly the same performance for less money.

And the DGS-108GL model from here:
As you have seen, both the DGS-105/108 and the DGS-105GL / 108GL family are very similar, but they have important differences that you should know about, because if you buy the DGS-108GL and have IPTV services with multicast traffic you will have problems for not having IGMP Snooping. In RedesZone you can read the analysis of both unmanageable 8-port Gigabit Ethernet switches, the two computers are highly recommended for home environments as they are very cheap, robust and will provide us with excellent performance.
