The Zyxel CX4800-56F is a high-density L3 aggregation optical switch in which the company pioneered the use of 100G ports: 8 QSFP28 100GbE uplinks complement 48 SFP+/SFP28 slots with 10/25gbe support, forming a single 56-port stack for traffic aggregation in campus and data centers factories. With a pass-through switching matrix of up to 4 Tbit/s and forwarding speeds of up to 2 billion packets per second, this switch confidently closes scenarios of highly loaded highways, where not only ...

We have a rather interesting class of L3 switches in front of us: multi-gigabit PoE models with a relatively small number of ports, an average PoE budget by modern standards, but 10-gigabit uplinks. They are interesting because the manufacturer has placed 2.5G PoE + 10G in a compact 9-inch rack housing with a silent fan, and such a switch can be installed at home, in a 1-room office, under a false ceiling or in narrow telecommunication cabinets. We have a rather interesting class of L3 ...

We will take two switches: the Taiwanese brand Zyxel and the Chinese counterpart from a little-known manufacturer and look at the design differences and what they affect in order to answer the question - does it make sense to overpay for design features? It's no secret that almost all modern electronics are manufactured in China, even if they are developed in the USA, Europe, Japan or Taiwan – the Chinese have not only learned how to do things efficiently, but have also grown such IT giants ...

This is a 28-port switch, in which 4 ports are gigabit optics for Uplink, and the remaining 24 ports are 1-gigabit RJ45 PoE with a total power budget of 370 watts, and each of these ports can work both in 802.3af mode (up to 15.4 watts) and and in the mode 802.at (up to 30 watts). When integrating into the project, some features of this switch should be taken into account. Level 3 switches with PoE support are usually used to build enterprise Wi-Fi networks and video surveillance systems. And ...

Zyxel reasoned this way: if the L3 functionality is already determined only by the firmware, 99% choose an access switch for the sake of port density, PoE, VLAN, Multicast, and less often for static routing, then here's the base model XMG1930, which is generally L2, but slightly L3. And if your network requires advanced L3 functions, then all this is also there, just buy the appropriate license and get the core-level functionality. You can do this at any time, even when buying a device, even ...

This L3 layer switch has 4 x 10-Gigabit SFP+ slots, 1-Gigabit PoE+ ports for the main fleet of devices, NVR/VoIP optimized interface, support for Nebula cloud service and multi-Gigabit PoE+ ports for Wi-Fi 6 access points. That is, Zyxel has added a maximum of functions to make it the most versatile. In the Zyxel hierarchy, the XGS2220 series refers to access switches, that is, to the lowest level that serves end devices and access points. We are used to the fact that cheap maintenance-free ...

From the point of view of the network, a modern facility can be just one access point connected directly to the WAN from the provider, and there are enough resources on this access point to raise the VPN tunnel to the headquarters, and for NAT, and to configure restrictions for customers and for basic protection of customers and employees. No, but really, why should an expensive security gateway be built on a small facility where the network infrastructure is completely wireless? Modern ...

What will happen to your network if the Iron Curtain suddenly falls, and the Global Internet turns into something sovereign and all cross-border channels are blocked? Let's simulate this situation and tell you how to unsign the device from Nebula without Internet access. We have reviewed the Nebula Control Center management system from Zyxel many times. This is a cloud service that allows you to configure and monitor the company's network stack via the Internet, including setting up Wi-Fi, ...

Modern Zyxel access points allow you to work in NAT and bridge mode simultaneously for different SSIDs, connect users using 2FA, shape traffic depending on the application and flexibly use VLANs. Let's look at how you can configure a wireless network to protect horizontal traffic. Modern networks are gradually changing the traditional topology, in which a security gateway was installed on top, and the network was segmented at L2/L3 levels using switches from below. The modern network is ...

Let's consider a typical case: a large retail chain opens hundreds of new stores, each of which plans to use IoT infrastructure using Wi-Fi 6. In order to facilitate the setup and commissioning of equipment, in other words, so that the sysadmin does not hang around all 100 stores, you can turn the deployment process upside down: first set up the network, and then lay the cables and mount the devices. Today ZyXEL provides you with such an opportunity when using the Nebula service. Let's ...
