What are the main products of Cisco? Cisco provides IT products and services across five major technology areas: networking (including Ethernet, optical, wireless and mobility), security, collaboration (including voice, video, and data), data center, and the Internet of things.

What is a Cisco network switch? A switch connects devices within a LAN (local-area network) by using MAC addresses to identify where to send data packets. A router connects LANs to other area networks or to the internet. A router uses IP addresses to route data packets.

What is a Cisco switch used for? Cisco Router and switch, both are the connecting devices in networking. Where a router chooses the smallest path for a packet to reach its destination, a switch stores the arrived packets, process it and forwards it to the specified destination.

What is a Cisco 9300? Is Cisco 9300 Layer 3? When was Cisco 9300 released? What is the difference between Cisco 9200 Series and 9300? Is 9200 a layer 3 switch? Are Cisco 9200 switches Layer 3? Is 2960 a layer 3 switch? Is c9300 a switch or router?

PoE+ technology (IEEE 802.3at standard) is an upgraded version of PoE technology, released in 2009. PDs on the market tend to require higher wattages, for example wireless access points require more than 12.95W of PoE wattage to function properly. To solve this problem, PoE+ technology was created to support high power consumption.

For S-series switches (except S1700) and E-series switches, the TCP connection establishment process includes three handshakes, and the handshake data sent by the passive party carries RST or ACK flags, and does not carry other flags such as SYN, etc. Therefore, it is only necessary to configure ACLs on the passive party to allow TCP messages carrying RST or ACK to pass, and disallow TCP messages carrying other flags to pass. TCP messages carrying RST or ACK are allowed to pass, and TCP messages

NVIDIA has announced the launch of its latest networking switches, the X800 series, designed specifically for AI applications. The Quantum-X800 InfiniBand and Spectrum-X800 Ethernet switches offer unmatched throughput of 800Gb/s, catering to the demanding computing needs of data centers. Industry giants like Microsoft Azure and Oracle Cloud Infrastructure have already adopted these switches, recognizing their importance in advancing cloud AI infrastructure.
