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 ...

Switch stacking technology allows you to combine several physical switches into one virtual switch, combining their switching matrices and simplifying port management from a single stack web interface. One of the most popular functions of the stack is to combine ports from different switches into common lagging groups to get a fault-tolerant network that can withstand the breakdown of N-(N-1) switches. I want to draw attention to the fact that modern Zyxel combines support the connection of up ...

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 ...
