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.

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 ...

A typical IoT attack looks like this: the device connects to a malicious Internet resource directly or through its own VPN, downloads and installs malicious code on itself, after which it begins to be either part of a large bot farm for attacks on third-party resources and use as a resident proxy, or simply spies on your network, trying to intercept anythat data, pull information from open resources or harm in any other way. It is not difficult to protect your network from possible IoT attacks. ...

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 ...
