We are giving specifications below, why one should consider procuring Cisco 24 Port Switch Networking features, a general overview, description, performance specification, relevant images, a competitive price infographic, and technical information about the WS-C3750G-24PS-S model with compatibility.

Advanced Features and Security

The WS-C3750G-24PS-S is a Cisco Catalyst 3750 model switch that has 24 ports and is Power over Ethernet (PoE) capable. It is a Layer 3 switch, which means it can perform routing functions in addition to switching.

Advanced Features:

  • Quality of Service (QoS): The switch allows you to prioritize network traffic based on various parameters such as IP address, port number, or protocol, which is useful for ensuring that critical applications receive the bandwidth they need.
  • StackWise technology: This technology allows multiple switches to be grouped together as a single logical unit, which simplifies management and increases the available ports and bandwidth.
  • EnergyWise technology: This technology allows you to monitor and manage power consumption on the switch, which can help reduce energy costs and increase the efficiency of your network.
  • Virtual LAN (VLAN) support: The switch supports VLANs, which allows you to segment your network into smaller, more manageable segments. This is useful for isolating different types of traffic and improving security.

Security Features:

  • Access Control Lists (ACLs): This feature allows you to create rules that specify which traffic is allowed to enter or leave the switch, which is useful for preventing unauthorized access to your network.
  • Secure Shell (SSH) support: SSH is a secure protocol for remote access to the switch, which is useful for managing the switch remotely without exposing it to potential security threats.
  • IEEE 802.1X port-based authentication: This feature allows you to authenticate users and devices before they are granted access to the network, which improves security by preventing unauthorized access.
  • Cisco IOS Firewall support: The switch supports Cisco IOS Firewall, which provides stateful packet inspection and other advanced security features for protecting your network against various types of attacks.

Additionally, the switch is manageable, meaning it can be configured and monitored remotely using Cisco's proprietary software, such as Cisco IOS or Cisco Prime. This allows you to easily manage your network from a central location and monitor its performance in real-time.

Simplifying Network Management

The WS-C3750G-24PS-S Cisco Catalyst 3750 switch includes several features that simplify network management:

  • StackWise technology: This technology allows multiple switches to be grouped together as a single logical unit, which simplifies management and increases the available ports and bandwidth. This allows you to manage multiple switches as if they were a single device, reducing the complexity of your network.
  • Cisco IOS software: The switch runs on Cisco IOS software, which is a powerful, feature-rich operating system that allows you to easily configure, monitor, and troubleshoot your network.
  • Cisco Prime: Cisco Prime is a network management software that allows you to manage your Cisco devices from a single, centralized location. It provides real-time monitoring and troubleshooting capabilities and allows you to easily configure and manage your network.
  • Cisco SmartPort macros: SmartPort macros are predefined configurations that can be applied to switch ports to simplify the process of configuring ports for specific network functions. This allows you to quickly configure ports for different types of devices, such as servers, printers, or IP phones.
  • EnergyWise technology: This technology allows you to monitor and manage power consumption on the switch, which can help reduce energy costs and increase the efficiency of your network.
  • SNMP support: Simple Network Management Protocol (SNMP) allows you to monitor and manage the switch remotely using third-party network management software. This allows you to easily monitor the health and performance of your network and quickly identify and resolve issues.

All of these features work together to make it easier to manage and maintain your network, allowing you to focus on more important tasks.

Maintenance and Support

The WS-C3750G-24PS-S Cisco Catalyst 3750 switch requires regular maintenance to ensure it continues to operate correctly and securely. The following are some key maintenance tasks to keep in mind:

  • Firmware updates: It is important to keep the firmware of the switch up to date to ensure it has the latest security updates and features. Cisco releases firmware updates on a regular basis and it is recommended to stay current with these updates.
  • Backups: It's important to regularly back up the configuration of the switch to ensure that you can restore the switch to a known good state if something goes wrong.
  • Monitoring: Regularly monitoring the switch's performance and usage can help you detect and resolve issues before they become major problems. You can use built-in monitoring tools such as Cisco Prime or third-party software to monitor the switch.
  • Physical maintenance: Regularly cleaning the switch, ensuring proper airflow and checking the temperature can help prevent hardware failure.
  • Security best practices: Implementing security best practices such as using strong passwords, disabling unnecessary services, and using firewalls, can help prevent unauthorized access to the switch.

Cisco offers different types of support for the WS-C3750G-24PS-S switch, including technical support, software updates, and hardware replacement. Customers can purchase a support contract directly from Cisco or through a Cisco partner. The level of support purchased will determine the level of access to Cisco's technical support and the types of services provided.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
