Cisco Switch

Cisco Switch:

As you know, switch is a kind of devices in network equipment that connect several devices together. There are a lot of companies that provide it and sell in network equipment market.

Cisco is a very famous company that produces different types of switches in high quality. Cisco switches are really famous between organization, IT experts.

What is cisco switch:

Cisco switches designed by cisco company that situated in San Joes, California, US. This company stablished in 1984 by Leonard Bosack and Sandy Lerner. This company produces different types of network equipment such as router, server, network switch, module, Ip phone, .. . every year according variety of technologies, cisco company 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 because of this topic there are many types of cisco switches which some of them expired, some of them is new and maybe some of them will expire in next years.

Some key features of cisco switch:

• VLAN Support: Cisco switches can segment a network into virtual LANs, improving security and reducing broadcast traffic.
• Quality of Service (QoS): Prioritizes network traffic to ensure that critical applications receive the necessary bandwidth.
• Redundancy and Reliability: Many models support protocols like Spanning Tree Protocol (STP) to prevent loops and ensure network reliability.
• Security Features: Include port security, access control lists (ACLs), and support for secure management protocols.
• Scalability: Cisco switches can be stacked or managed in clusters to accommodate growing networks.
•Switch speeds: Network switches are available in different throughputs or speeds, the rate they transmit data in megabits per second (Mbps). For example, fixed-configuration switches can provide Fast Ethernet (10/100 Mbps), Gigabit Ethernet (10/100/1000 Mbps), Ten Gigabit (10/100/1000/10000 Mbps), and even 40/100 Gbps (gigabits per second) speeds. The switch speed you choose depends on the type of throughput you need. If, for example, you need to move large data files on a regular basis, you should consider a Gigabit Ethernet switch.
•Number of ports: As is the case with switch speed, the number of ports available in a switch can vary. The bigger your small business and the more network users you have, the more ports you’ll need. Fixed-configuration switches are usually available with five, eight, 10, 16, 24, 28, 48, or 52 ports.
•Power over Ethernet (PoE) vs. non-PoE: PoE lets you power a device, such as an IP phone, surveillance camera, or wireless access point over the cable that is used for data traffic. This allows you to place endpoints anywhere, even in those areas that are usually difficult to reach. Switches with PoE are more expensive, however. As you evaluate your options, think about the devices you would like to connect to determine whether PoE is required.
• Stackable vs. standalone switches: As your business (and your network) grows, you will likely need to support more and more devices, which will mean investing in more switches. Just as its name implies, a standalone switch is managed and configured as an individual entity with limited capacity. If there is a problem, troubleshooting is also switch specific.

Categories of cisco switches:

There are two main categories of switches: modular and fixed configuration. There are variations among these categories of network switches, but the primary definition of each remains the same.
-Modular switches: Modular switches let you add expansion modules as needed, giving you flexibility as network requirements change. Expansion modules are application-specific and include those for firewalls, wireless connectivity, or network analysis. They may also allow for additional interfaces, power supplies, or cooling fans. This type of switch provides you with the most flexibility, but at a higher cost.
-Fixed-configuration switches: Fixed-configuration switches provide a fixed number of ports and are typically not expandable, which makes them less expensive overall. Fixed-configuration switches include unmanaged switches, smart switches, and managed switches.
-Unmanaged switches: Unmanaged switches are typically used to provide basic connectivity. They’re designed to be plug and play; no configuration is needed. Unmanaged switches are most effective when only basic switching and connectivity are required. You will often see them in home networks or wherever only a few ports are needed, such as at a desk, in a lab, or in a conference room. Some unmanaged switches do offer limited advanced capabilities, however as the name implies these switches generally cannot be modified or managed.
-Managed switches: Among fixed-configuration switches, managed switches are designed to deliver the most comprehensive set of features to provide the best application experience, the highest levels of security, the most precise control and management of the network, and the greatest scalability. As a result, managed switches are usually deployed as aggregation/access switches in very large networks or as core switches in smaller networks. Managed switches are the most expensive option of fixed-configuration switches and are most common in organizations with large or growing- networks.
