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 ...

If your company uses Zabbix for infrastructure monitoring, you can integrate Keenetic routers and access points into this platform by following our instructions. This greatly facilitates network maintenance and incident investigation. In all cases when I came across the use of Keenetic in business, none of the owners set up means of active monitoring of these devices, even if there were two or three dozen access points. There can be many reasons for this, ranging from banal laziness and lack ...

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 ...

Let's talk about the advantages of IPv6-based segment routing technology, which displaces LDP tag allocation and network resource reservation protocols, RSVP on the example of a 10-gigabit router for small businesses and consider how FlexE technology helps to maintain a guaranteed bandwidth level for customers. . In recent years, more equipment for routing network traffic has been supplied under the Huawei brand than under other brands, and part of the merit of the company is that it was at ...

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 ...

One of the ways to protect a web service may be to restrict access to it by IP, including GeoIP, based on the user's location. We will set up protection without using paid services, without Maxmind, without registration and SMS Today, many organizations that transfer their services to web platforms are forced to provide an entry point to the Internet for user authentication. Even with 2-factor authentication, a web service accessible via the Internet remains vulnerable to complex attacks, the ...

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 ...
