Cisco network switches deliver performance and security. Cisco switches are scalable and cost-efficient and meet the need of any size of business.
Cisco has a comprehensive portfolio of network switches and switching solutions for enterprise networks, data centers, and small businesses.
Linkom-PC offers Cisco switches for networks of all types and sizes and provides technical support to help you find the right Cisco switch for your business.
Switches are the fundamental interconnect component of the campus network. Cisco offers a variety of switches specifically designed for different functions. At the time of this writing, Cisco designs the Catalyst switches for campus networks and Nexus switches for data centers. In the context of CCNP, this book focuses mostly on Catalyst switches.
Cisco delivers a comprehensive portfolio of switching solutions for Enterprise Networks, data centers, and smaller businesses. These solutions are optimized for a wide range of industries, including service providers, financial services, and the public sector.
When it comes to selecting a Cisco Switch either a new Switch or need an upgrade an existing Cisco Switch one needs to consider many things be it the feature set, type of modules needed, wither it need be a stackable or modular switch.One has to go through many parameters, which may some times results in selecting wrong switch.
Despite its extremely long life cycle, Cisco marketing has finally shifted focus to the Catalyst 6800. For a large number of you reading this book, you have likely come across the Catalyst 6500 at some point in your career.
Cisco within Cisco Switch Selector offers two types of network switches: fixed configuration and modular switches. With fixed configuration switches, you cannot swap or add another module, like you can with a modular switch. In enterprise access layers, you will find fixed configuration switches, like the Cisco Catalyst, 2960-X series. It offers a wide range of deployments.
In the enterprise distribution layer, you will find either fixed or modular switches depending on campus network requirements. An example of a modular switch that can be found in the distribution layer is the Cisco Catalyst 3850-X series. This series of switches allows you to select different network modules (Ethernet or fiber optic) and redundant power supply modules. In small businesses without a distribution layer, the 3850-X can be found in the core layer. In large enterprise networks, you might find 3850-X in the access layer in cases where high redundancy and full Layer 3 functionality at the access layer are requirements.
In the enterprise core layer, you will often find modular switches such as the Cisco Catalyst 6500 or the Catalyst 6800 series. With the 6800 switch, nearly every component, including the route processing/supervisor module and Ethernet models to power supplies) is individually installed in a chassis. This individualization allows for customization and high-availability options when necessary.
If you have a network where there is a lot of traffic, you have the option to leverage the Cisco Catalyst 4500-X series switches into the distribution layer. The Catalyst 4500-X supports supervisor/route process redundancy and supports 10 Gigabit Ethernet.
All switches within the Cisco Switch Selector and the 2960-X, 3850-X, 4500-X, and 6800-X series are managed. This means that you can configure an IP address on the device. By having a management IP address, you can connect to the device using Secure Shell (SSH) or Telnet and change device settings. An unmanaged switch is only appropriate for a home or very small business environment. It is highly recommended not to use an unmanaged switch in any campus network.
