The need for smart, high-speed switching is driven by a confluence of fairly new networking patterns whose net effect is a virtual tsunami of data: Progent can assist you to manage and troubleshoot your legacy Catalyst switches or migrate smoothly to current models of Catalyst switches adhering to industry best practices to ensure that you realize the most business value from your investment in your IT infrastructure. Progent's Cisco-certified CCIE consultants offer online and onsite expertise with Catalyst family switches to assist your organization to plan a cost-effective infrastructure that addresses your unique business requirements, configure proof-of-concept testing systems, deploy Catalyst switches, establish and validate a sound security plan, automate network management and monitoring, deliver repair and support services, optimize switch performance, and configure Catalyst's fault-tolerant technology to achieve non-stop operation. The Catalyst line of modular and fixed-configuration managed switches offers performance and intelligence at the access, aggregation, and core levels of converged voice, HD video, and data networks for organizations that range in size from small businesses and branch offices to global enterprises and SPs. However, because the look and feel of the user interface resembles the router IOS interface, most people simply call the 2950, and other switches that use the same CLI, IOS-based switches.Cisco Catalyst Switches Consulting and Support

For instance, Cisco calls the 2950 operating system the 2950 switch software instead of IOS. Even though the switches have a similar look and feel to the router IOS, they do not actually run the same IOS as the routers because switches and routers do not share a lot of the same functions and features.

So, Cisco was faced with a dilemma: Should it update all the Crescendo Catalyst switches to use a user interface like the routers? Should it just continue to use the Crescendo Catalyst OS, now typically called the Cat OS, and that alone, on all future switches? The answer: Some Cisco switches use the Cat OS CLI, and some use the IOS CLI.Ĭisco IOS switches use the same CLI as the router IOS.
At the time of acquisition, Cisco already had sold a lot of routers, and, not surprisingly, those routers had a different user interface compared to Crescendo's switches. When Cisco first entered the LAN switching arena, it did so by acquiring Crescendo Communications, which at the time, sold a line of switches called Catalyst switches.
2950 Switch Operating SystemĬisco switch operating systems can be categorized into two types: Internetwork Operating System (IOS) switches, and Catalyst Operating System (Cat OS) switches. The first interface is numbered 0/1, the second is 0/2, and so on. On a 2950, the number before the / is always 0. Each interface has a number in the style x/y, where x and y are two different numbers. Switch commands refer to the the physical RJ-45 Ethernet connectors on a 2950 as interfaces. You will read more about GBICs in Chapter 11, "LAN Cabling, Standards, and Topologies." This switch also includes two Gigabit Ethernet slots, on the right side of the figure, into which you can put the appropriate Gigabit Interface Converter (GBIC). Any of the ports can be used to connect to end-user devices or to other switches. This particular model comes with 24 built-in 10/100 ports using RJ-45 connectors.
You would also use a couple of Ethernet ports to connect to other switches to provide connectivity between the wiring closet and the rest of the network.įigure 8-1 shows one model of a 2950 switch, the 2950-24-EI switch, which provides 24 10/100 Ethernet interfaces and two Gigabit interfaces. That means that you would expect to use this switch as the connection point for end-user devices, with cabling running from desks to the wiring closet.

Cisco positions the 2950 series of switches as a full-featured, low-cost wiring closet switch. Inside each family are several specific models of switches. Cisco produces a wide variety of switch families.
