According to the company, the volume of network connections in the industrial sector of the economy as of February 2022 is growing exponentially, as organizations strive to optimize work efficiency, employee safety, business dynamics and implement hybrid work organization models. As this segment evolves, companies need to optimize their training to scale and secure enterprise networks as they deploy operating technology (OT )-based systems.

According to Gartner, "the majority of Chief information officers are responsible for making decisions on OT systems: 82% of respondents say that the responsibility of the Chief information officer for the OT system has increased over the past 3 years, and 89% say that it will increase in the next 3 years."

IT and OT interact more than ever and need collaborative tools to scale and protect the network. Automation, segmentation, and proactive problem detection and resolution are key to success. This functionality is available in commercial enterprises, but is not as widespread in industrial networks. Without enterprise-level network infrastructure features, IT/OT resources are becoming increasingly limited, putting deployment projects of various solutions at risk.

Cisco Catalyst Industrial Ethernet 9300 switches combine enterprise functionality with industrial protocols in systems with a form factor designed to operate in complex industrial environments.

Our customers meet the challenges of moving to green energy and improving grid reliability, and the critical nature of these environments requires a network infrastructure with enterprise-level security, control, and automation capabilities. told Vikas Butaney, Vice President and CEO of Cisco IoT

Based on the Cisco Unified Access Data Plane (UADP) ASIC, Catalyst IE9300 switches offer a wide range of functionality. They provide enterprise-level switching in an enhanced-design form factor and offer advanced capabilities for controlling, securing, and performing calculations in edge environments.

Implement the zero trust concept with the built-in Cisco Cyber Vision sensor and SD-Access functionality. Catalyst IE9300 - Switches that provide zero-trust security in operating environments.

2019: Catalyst Wi-Fi 6 and Catalyst 9600 Access Points

Cisco on June 11, 2019 introduced innovative solutions that will help customers enter the era of wireless communication. According to representatives of the company, Wi-Fi 6 (802.11ax) technology opens up wide opportunities in the field of digital transformation, immersive applications and connecting billions of objects, in particular the Internet of Things.

According to Cisco, the extended Catalyst portfolio does not simply support Wi-Fi 6. Thanks to the availability of customizable programmable chipsets and access to analytics technologies, they allow you to build smart and secure wireless networks. Another feature of access points is their "multilingualism," that is, the ability to work with various IoT protocols, including BLE, Zigbee and Thread.

At the same time, Cisco introduced the Catalyst 9600 line of trunk switches, which will serve as the basis for the operation of any network. The key to working safely in a wireless network is that the organization has a single network structure that combines wired and wireless technologies. The Catalyst 9600 switch, the successor to the Catalyst 6000 model, will be the foundation of the next generation of intensely oriented networks.

Prior to running Wi-Fi 6 hotspots, Cisco, together with Intel and Samsung, conducted interoperability testing. Cisco also led an open roaming project designed to eliminate one of the main pain points of wireless communication. Samsung, Boingo, GlobalReach, Presidio and other companies joined the project. The goal of the consortium is to facilitate a seamless and secure transition between Wi-Fi and LTE networks, as well as connecting to public Wi-Fi networks.

2018

Catalyst 9200 Switch and Catalyst 9800 Wireless Controller

On November 14, 2018, Cisco announced the expansion of the Cisco Catalyst 9000 switch portfolio to all access levels for wired and wireless networks, including branch offices. As a result, the Internet-oriented network model can be implemented in a project of any scale, and even more customers will receive smarter, simpler and more secure networks based on it, Cisco claims.

"We are committed to ensuring that IT departments have all the tools they need to automate and control networks. Our expanded Catalyst 9000 switch portfolio provides customers with such capabilities not only in large wired networks, but also in wireless networks and in simple branch office networks. "

Intentional (or intent-based) networks use fundamentally new approaches to network building and management. This is a significant step forward compared to traditional technologies - requiring constant attention from support services and unprotected from manual control errors. These innovative networks adapt to business goals and translate them into network policies. Thus, the network can be automatically configured within a few minutes - and without errors, the manufacturer emphasized.

As noted in Cisco, the Cisco Catalyst 9000 switches were originally designed for intensely oriented networks. They operate under a single open and programmable operating system that also manages all products for access networks and WAN. This helps Cisco customers innovate faster, simplify IT operations, and reduce costs. One software controller is responsible for automation of the entire network, the use of programmable ICs provides a high degree of investment protection. At the same time, information security technologies are not made in the form of an add-on, but are built directly into the network.

Cisco Introduced Devices to the Catalyst 9000 Lineup:

• Wireless controller. Customers can implement information security, automation, and analytics services for wired and wireless environments using the same operating system. The Cisco Catalyst 9800 Series Wireless Controller can function anywhere - built into Catalyst 9000 switches, locally, in any cloud. The controller supports existing wireless standards and is ready for the 802.11ax standard. It also increases support for wireless services due to the ability to "hot" software updates, threat protection and programmability, the manufacturer claims.
• Switch for medium-sized enterprises. The introduction of Catalyst 9200 switches has expanded intuitive networks to branch and midsize enterprises. Medium-sized businesses access a complete set of enterprise-level services at the price of the previous generation of Cisco switches. At the same time, the level of reliability and security, according to the manufacturer, will not deceive the expectations of customers operating switches of the Catalyst line.

The Catalyst 9800 Wireless Controller will be available in Q4 2018. Catalyst 9200L switches will be available in Q4 2018, Catalyst 9200 in Q1 2019.

Cisco Catalyst 9000

As of February 2018, Catalyst 9000 Switches are offered under long-term subscription contracts.  By purchasing this hardware, customers access the software features of the Digital Network Architecture by subscription - either with the help of the Cisco ONE software suites, or by choosing the necessary components. By acquiring POCisco ONE, designed for the entire portfolio of enterprise network solutions, companies gain constant access to innovation, predictability of budget and high maneuverability in the application of technology, Cisco says.

By February 20, 2018, the number of customers who switched to the Catalyst 9000 platform exceeded 3100, which is almost three times more than three months earlier.

This is the fastest introduction of a new product in our history and a fantastic example of the innovations that we have achieved in the last two years, "said Cisco Chairman and CEO Chuck Robbins during a conference with analysts to publish the company's financial statements.

According to the head of Cisco, the Catalyst 9000 switches quickly became successful due to the company's activity in the channel, as well as proper pricing.

For our customers, we wanted to make the basic subscription with the product cost as much or less than what they paid for their previous switch, taking into account the permanent license for it, "Robbins noted.

He also emphasized that Catalyst 9000 devices go beyond the original scope of use - branch offices and remote offices - and penetrate data centers and large corporations.

By February 2018, Cisco has more than 800 thousand customers, so the company has a large field of work with respect to Catalyst 9000 products, Chuck Robbins said.^[1]

2015

Cisco Catalyst 4500E/3850/3560-CX

In January 2015, Cisco updated the Catalyst line of switches, adding models that allow enterprises to deploy high-speed wireless networks without replacing extended cables.^[2]

The announced Cisco Catalyst 4500E, Catalyst 3850, and Catalyst 3560-CX switches, which form a single physical infrastructure for wired and wireless networks, received ports at speeds of 1, 2.5, 5, and 10 Gb/s. New here are 2.5 and 5 Gb/s (2.5G and 5G) technologies that can work with the existing cable infrastructure, which in many companies is built on Category 5e and Category 6 copper wires.

New Cisco Switches Help Deploy Fast Wi-Fi Without Cabling Updates

With new switches available in the second quarter of 2015, organizations can easily install Wi-Fi 802 11ac Wave 2 hotspots that deliver up to 7 Gb/s of wireless data without the need to pull expensive Category 6a cables.

The new products are compatible with the Catalyst models already available on the market and can be phased in to companies using Cisco switches. For example, the Catalyst 3850 can work in tandem with the current 1G Copper and 1G Fiber solutions. The Catalyst 4500E supports additional line cards that enable collaboration with Supervisor Engines 8-E, 7-E, and 7-LE switches.

Deploying high-speed wireless networks such as Wi-Fi 802.11ac Wave 2 requires high Ethernet bandwidth. Migrating to 10 Gb/s (10GbE) requires low-cost installation of Category 6a cables. This is not necessary for 2.5G and 5G technologies, which occupy an intermediate position between Gigabit Ethernet and 10GbE. Thus, 2.5G and 5G are an inexpensive way to scale the capacity of enterprise networks.

The promotion of 2.5G and 5G technologies in access points and other equipment is carried out by the MGBASE-T Alliance, which was formed in June 2014.

Cisco Catalyst 6840-X

Cisco introduced the Cisco Catalyst 6840-X trunk switch in September 2015. It meets the requirements of the network backbone and is designed, in particular, for installation in a limited space. According to the Visual Networking Index, network traffic has grown exponentially over the past few years and will continue to grow in the near term. By 2018, the network will have more than 20 billion devices, that is, twice as many as in 2011. According to forecasts, the monthly volume of corporate IP traffic by 2016 will reach 13.1 exabytes.

As the number of devices grows, so does the speed of wireless connections. The 802.11ac gigabit wireless transmission standard tripled the network speed to 1.3 Gb/s, and 802.11ac Wave 2 even more than doubled. Thus, bottlenecks move "up the network," from wireless access points to backbone links aggregating connections of such points. If 1 Gb/s becomes standard for client ports on access switches, 10 and 40 Gb/s should be used on trunks.

To promote business growth, the network must be scalable and meet future traffic needs while protecting investments. Most network engineers, in principle, agree with this approach, but the number of enterprises that actually adhere to it is still small. According to a Dell'Oro Group report, the problem is not technology (there are enough products on the market to work with gigabit speeds). The matter is the economics of network modernization, where factors such as the cost of equipment, the cost of modernization and the provision of promising parameters come into play.

To address these issues and enable simple and cost-effective network upgrades to support the mobile and video avalanche, Cisco released the Cisco Catalyst 6840-X switch.

The Catalyst 6840-X is a fixed 2RU trunk switch designed to transmit video and other applications that require high bandwidth. The switch supports 10 Gb/s for client connections and 10/40 Gb/s for trunks.

2014

Cisco Catalyst 3750 Series Switches

As of October 2014, the Cisco Catalyst 3750 Series switches are a premier line of enterprise-class, stackable, multilayer switches that provide high availability, security, and quality of service (QoS) to enhance the operation of the network. Its innovative unified stack management raises the bar in stack management, redundancy, and failover.

With a range of Fast Ethernet and Gigabit Ethernet configurations, the Cisco Catalyst 3750 Series can serve as both a powerful access layer switch for medium enterprise wiring closets and as a backbone switch for mid-sized networks.

2013

Cisco Catalyst 6500

As of March 2013, the Cisco Catalyst 6500 series switches are a family of high-performance tiered switches focused on enterprise networking.

This series is based on the Catalyst 6503, Catalyst 6506, Catalyst 6509, Catalyst 6513, and Catalyst 6509-NEB (the model is designed for carrier applications that meet the NEBS Level 3 standard; the model differs from the WS-C6509 switch in the vertical position of the slots and the direction of ventilation flow from the front wall to the rear)

The Catalyst 6500 series is a family of high-performance modular switches running on L2-L7 layers. Catalyst 6500 switches can be used in large enterprise, carrier, urban, distributed computing networks. Depending on the configuration, the Catalyst 6500 can be installed at access, distribution, and trunk levels.

Characteristics:

• Highest flexibility and scalability: The Catalyst 6500 series provides scalable performance (up to 720 Gb/s) and port density (up to 576 Gigabit Ethernet ports or 32 10 Gigabit Ethernet ports). The switch is a chassis in which power supplies and various types of modules are installed:

• System modules called supervisors. The system module is a required component of any Catalyst 6500 switch.
• Interface modules that implement a wide range of network interfaces.

• Service modules that hardware implement additional functionality, in particular, firewall, traffic monitoring and analysis, intrusion detection system.

There are several chassis options (with 3, 6, 9 and 13 expansion slots), as well as complies with the NEBS Level 3 model for carriers.

• High Speed Routing - With Distributed Cisco Express Forwarding (dCEF) technology, Catalyst 6500 switches provide traffic routing at speeds of up to 400 million packets per second. Hardware routing of IPv4 and IPv6 traffic is supported (RIP, OSPF, IS-IS, EIRGP, BGP4, MBGP, PIM, DVMRP), hardware implementation of MPLS functionality, as well as NAT and GRE. IPX, AppleTalk, DECnet, VINES, XNS, CLNS traffic routing is supported.

• High availability is achieved by fully redundant, hot-swappable hardware components (including system modules, power supplies, expansion modules). Switching from a failed system module to a healthy one occurs automatically within 2-3 seconds while maintaining active TCP connections and routing protocol status. Supports load balancing on power supplies, Ether Channel link combining functionality for ports on different modules, MISTP, HSRP (255 groups), 802.1w/802.1s, PortFast, UplinkFast, BackboneFast, PAgP, PVST +, and VRRP and GLBP.

• Wide choice of interfaces and rich functionality: interfaces 10 Gigabit Ethernet (LR, ER), Gigabit Ethernet are supported (SX, LX/LH, ZX, T), Fast Ethernet (TX, FX), Ethernet (FL), CWDM, ATM (OC-12, OC-3), ChOC (OC-48, OC-12), PoS (OC 48c, OC-12c, OC-3c), T1/E1, T3/E3, HSSI, FXS. A wide range of modules allows you to fill the Catalyst 6500 with functionality that is optimal for a particular network.

• High security: 802.1x protocol support, Identity functionality - Based Networking Services (IBNS), hardware-implemented layer 2/a access lists (no performance degradation), Private VLAN functionality, MAC address and protocol filtering, persistent ARP entries, Port Security, etc. For security, administration supports SSHv1, SSHv2, and SNMPv3 protocols, as well as centralized authentication on TACACS + and RADIUS servers.

• Enhanced Quality of Service (QoS) support: hardware implementation of quality of service mechanisms, including classification (L2/3), polishing, traffic labeling, input (L2) and output (L2/3) queuing. Ability to limit bandwidth (including for individual users and streams), WRED.

• Excellent manageability: support for SNMP versions 1, 2, 3, RMON1, 2, SPAN, RSPAN, support for NetFlow technology, support for TDR (Time Domain Reflectometer) functionality by some Gigabit Ethernet interface modules for quick detection of cables at the physical level.

The Catalyst 6500 series includes several variants of system modules, which allows you to select the configuration that most closely matches the tasks and requirements of a particular network for the performance and functionality of the switch. Modern system modules include the following subsystems:

• PFC (Policy Feature Card) - performs hardware switching (L2/L3/L4), packet filtering through access lists (ACLs), and implements quality of service (QoS) mechanisms.

• MSFC (Multilayer Switch Feature Card) - provides the operation of routing protocols.

Earlier versions of the system modules (Supervisor Engine 1, 2) did not have an integrated switching fabric. The Switch Fabric Module (SFM) implements a 256 Gb/s switch fabric that provides all chassis slots with dedicated bandwidth. SFM is supported by the Supervisor Engine 2. The Supervisor Engine 720 system modules, in addition to the common bus, have a switching fabric and therefore do not need an SFM module, which frees up one to two chassis slots to install other modules.

Advanced system modules enable high-speed traffic routing with Cisco Express Forwarding (CEF) technology. To ensure that CEF works in distributed (dCEF) mode, the interface modules are equipped with daughter boards (DFCs), the version of which corresponds to the version of the PFC subsystem on the system module.

Cisco Catalyst 3850

As of March 2013 Switchboards Cisco , the Catalyst 3850 is one of the most important components of client device access to the combined wired and wireless network infrastructure. Their main difference is the integrated wireless LAN controller. In the Catalyst 3750 released earlier, the controller and switch were actually separate devices installed in the same chassis.

The 3850 switches are capable of terminating traffic based on the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel protocol, which is used in wireless networks to transmit data and control information between controllers and radio access points. The latter can now be connected to any port whose operation mode is determined during the configuration of the switch.

Due to bandwidth management, it is possible, in particular, to limit the bandwidth of guest access channels, evenly allocate bandwidth to various users, allocate privileged "wireless" users or their groups.

The Catalyst 3850 contains up to 48 ports per 10/100/1000 Gb/s power to the plug-in devices as required by IEEE 802.3at (PoE+). You can use additional modules with multiple gigabit or 10 gigabit ports to communicate with the "upper" network layers. Software support is provided for IPv4 and IPv6 routing, Flexible NetFlow protocol implementation, and advanced security features.

Up to four Catalyst 3850 switches can stack based on Cisco StackWise-480 technology, providing 480 Gb/s stacking performance. Such a stack can serve up to 50 access points and up to 2 thousand customers. The 48-port 3850 offers up to 40Gb/s wireless performance.

Unified wired and wireless traffic is handled on Catalyst 3850 switches by the new Cisco Unified Access Data Plane, a dedicated integrated circuit that Cisco also claims to be able to support software-based data-level management for SDN networks.

The same chips are installed in Cisco 5760 Unified Access WLAN Controller, running up operating system IOS to 60 Gb/s. They support up to a thousand access points and 12,000 simultaneous clients, the Flexible NetFlow protocol, can form converged networks of large enterprises together with the Catalyst 3850.

Program components of management of the unified access of Unified Access are the platform of identification and control of access of Cisco Identity Services Engine 1.2 and also the Cisco Prime Infrastructure 2.0 package which, unlike the former version, completely realizes functionality of a control system of life cycle of wireless networks Cisco Prime Network Control System and a control system of local networks Cisco Prime LAN Management Solution.

The Catalyst 3850 is Cisco's first integrated converged switch. Other manufacturers have already announced the release of such devices. One early example is the HP 3Com 2475-24G-PoE switch, which can be used to centrally manage both wired and wireless networks. Juniper Networks introduced a Universal Access solution last year, which, according to its developers, can combine access to wired and wireless networks.

2011: Cisco Catalyst C-Series (3560-C и 2960-C)

Cisco introduced the compact switchboards "C" series (Cisco C-Series) - the Cisco Catalyst 3560-C and Catalyst 2960-C - in early 2011, expanding the family of products that support the concept of networks without borders (Borderless Networks) and increase the security and efficiency of network and power connections outside distribution cabinets. The new switches are designed to be installed where there are serious limitations in the area of cable connections, working space and power supply. The new switches demonstrate Cisco's commitment to addressing unique customer challenges in any of the most unconventional networking environments in a situation where networks are becoming larger and more complex.

Cisco C-Series switches are compact versions of Cisco Catalyst 3560-X and 2960-S devices installed in distribution cabinets. They have the same functionality, work under the same control operating system and have the same control capabilities, but their sizes are half that of the X-box game console. Cisco C-Series switches allow you to implement highly secure user services, including unified communications, wireless access, IP video, and other applications, in an environment with limited cable connectivity, small workspaces, and insufficient power. Ethernet Cisco's first-in-the-industry Pass-Through PoE enables Cisco C-Series switches to operate in an environment where there are no electrical outlets. These features drastically simplify cabling and reduce infrastructure requirements. Other benefits of Cisco C-Series switches include:

• Ability to work in a wide variety of industries. If the Cisco Ethernet 3000 and 3010 industrial switches are designed for a harsh engineering environment and can operate under extreme temperature fluctuations, severe vibration, and other adverse factors, the Cisco Catalyst C-Series devices are designed for several different conditions. They provide flexible delivery of network services in an environment with unique requirements for cable connections, in which the absence of such specialized devices causes disruptions in normal business processes. This includes retail (points of sale, kiosks, checkpoints, warehouses), education (classrooms, dormitories, laboratories), medicine (doctor's office, hospital reception, patient examination room, laboratory), hotel business and entertainment industry (hotel room, cruise ship cabin, conference room, slot machine room, other gaming establishments), as well as the office environment.

• Dramatically reduce the cost of cable connections. Cisco C-Series switches eliminate the need to pull a separate cable to each network device, including a long distance from the distribution cabinet (for example, to each cash register in a large supermarket).

• Flexible placement of devices anywhere and anytime. Cisco C-Series switches can be installed up to 100 meters from the distribution cabinet. They are so compact and work so quietly (they do not have cooling fans) that they can be located directly on the desktop, under the table, under the counter or on the wall. The customer can quickly and easily install new devices of this type without supplying new cables.

• The independence of switches and IP devices from power sockets through the use - for the first time in the industry - of end-to-end PoE technology. End-to-end Ethernet power technology (Pass-Through PoE) delivers power to IP devices even where there are no power outlets. Cisco C-Series switches can receive power from a switch or a higher-level router (with PoE+/PoE features) installed in the distribution cabinet. At the same time, the Cisco C-Series switch not only receives energy for itself, but also transmits it to all IP devices connected to it.

• High level of security. Protecting remote devices from unauthorized access, eavesdropping, and theft is challenging. Cisco C-Series switches differ from other devices of this type in that they use the industry's most powerful network security solution, Cisco TrustSec. It provides the customer with the following benefits:
  • Network data is well protected because all packets on the link between the switch and the endpoint are encrypted at the source. This is a unique Cisco solution.
  • Strong information security rules are supported with custom IDs, job assignments, and device types (another unique Cisco solution). As a result, users can collaborate securely and flexibly anywhere in the network.
  • Attempts by attackers to eavesdrop on conversations or intercept data between two endpoints are blocked proactively.
  • Switch theft and unauthorized cable access can be prevented with option locks and cable cuffs.
  • Cisco C-Series switches support PCI (Card Payment Security Standard) specifications to meet all payment system regulations.

• Reducing energy costs. The Cisco EnergyWise technology allows to trace, control and reduce energy consumption of the devices connected to the switchboard. Under reduced load conditions, these devices can be turned off or switched to energy-saving mode. As a result, the customer will receive additional savings.

• Simplified configuration and unified network management. Cisco C-Series switches are initially configured using Cisco Catalyst Smart Operations, which does not require human intervention. In addition, this feature significantly speeds up the diagnostic processes. Another feature, Cisco Auto Smartports, automatically configures the switch depending on the type of devices connected to it. Automatic Quality of Service (QoS) allows you to implement the most modern IP telephony and video functions with just one command. The unique quality of Cisco services ensures the continuity of quality voice and video even with high network traffic. Cisco C-Series switches can be managed remotely with devices installed in the distribution cabinet, drastically reducing installation and management costs, eliminating the need to call qualified IT professionals.
