Advanced Features of 24 Ports Switch

The Cisco Small Business SG350XG-24T-K9-NA is a high-performance managed switch that offers a wide range of advanced features to improve network performance and security. Some of the key features include:

  • High-speed fiber connectivity: The switch has 24 SFP+ ports, allowing for high-speed fiber connectivity up to 10 Gbps. This makes it ideal for businesses that require high-bandwidth applications such as video streaming and file transfers.
  • Power over Ethernet Plus (PoE+): The switch supports PoE+, which allows devices such as IP phones and cameras to be powered through the Ethernet cable. This eliminates the need for separate power supplies, making installation and maintenance easier.
  • Layer 3 routing: The switch supports Layer 3 routing, which allows for advanced traffic management and enables businesses to create multiple virtual networks. This helps to improve network performance and security by segmenting traffic.
  • Quality of Service (QoS): The switch supports QoS, which allows businesses to prioritize mission-critical data, such as voice and video, to ensure that it is delivered with minimal delay and interruption.
  • Advanced security: The switch includes advanced security features such as DHCP snooping and IP source guard, which help to prevent unauthorized access to the network.
  • Link Aggregation Control Protocol (LACP) and Port Aggregation Protocol (PAgP) : The switch supports LACP and PAgP for increased bandwidth and redundancy.
  • Advanced Management: The switch supports VLAN,STP,LACP,IPv6,IPv4,IPv4 ACL,IPv6 ACL,IPv4 static routing,IPv6 static routing,ACL logging,sFlow,LAG,Port mirroring,LLDP which makes it easy to manage and monitor the network.
  • Energy Efficient Ethernet (EEE): The switch supports EEE, which reduces power consumption and helps to lower energy costs.
  • Easy Management: The switch can be managed via SNMP and a web-based user interface (UI), making it easy to monitor and configure the network.

Simplifying Network Management

The Cisco Small Business SG350XG-24T-K9-NA offers several features that simplify network management and make it easy for businesses to monitor and configure their network. Some of these features include:

  • Web-based user interface (UI): The switch can be managed via a web-based UI, which allows for easy access to the switch's configuration settings and monitoring tools. This eliminates the need for a separate management console and makes it easy for non-technical users to manage the network.
  • Smartports: The switch includes Smartports, which are pre-configured port templates that simplify the configuration of common network devices such as IP phones and cameras. This eliminates the need for manual configuration and ensures that devices are configured correctly.
  • Simple Network Management Protocol (SNMP): The switch supports SNMP, which allows for easy monitoring of the switch's performance and status. This can help to quickly identify and troubleshoot issues on the network.
  • Auto Smartports: The switch supports Auto Smartports, which automatically detects and configures devices that are connected to the switch. This eliminates the need for manual configuration and helps to ensure that devices are configured correctly.
  • Auto Voice VLAN: The switch supports Auto Voice VLAN, which automatically detects and configures IP phones that are connected to the switch. This eliminates the need for manual configuration and helps to ensure that IP phones are configured correctly.
  • Auto Surveillance VLAN: The switch supports Auto Surveillance VLAN, which automatically detects and configures IP cameras that are connected to the switch. This eliminates the need for manual configuration and helps to ensure that IP cameras are configured correctly.
  • Auto Smartports: The switch supports Auto Smartports, which automatically detects and configures devices that are connected to the switch. This eliminates the need for manual configuration and helps to ensure that devices are configured correctly.

All these features make the Cisco Small Business SG350XG-24T-K9-NA easy to manage and monitor, saving businesses time and reducing the chances of human errors.

Security and Quality of Service

The Cisco Small Business SG350XG-24T-K9-NA switch is a high-performance, manageable Layer 3 Ethernet switch that offers advanced security and Quality of Service (QoS) capabilities.

In terms of security, the switch supports a wide range of features to help protect your network against various threats. These features include:

  • Access Control Lists (ACLs) to control network access and restrict unauthorized access to sensitive data.
  • 802.1X authentication for wired and wireless access to ensure that only authorized users are able to access the network.
  • DHCP snooping to prevent malicious DHCP servers from providing false IP addresses to clients.
  • Denial-of-service (DoS) protection to help protect against network overload and service disruption.
  • Dynamic ARP inspection (DAI) to protect against ARP spoofing attacks.

In terms of QoS, the switch offers a variety of tools to help ensure that time-sensitive network traffic such as VoIP and video is delivered with minimal delay and jitter. These tools include:

  • Traffic shaping, which allows you to control the rate at which traffic is sent across the network.
  • Prioritization, which allows you to assign different levels of priority to different types of network traffic.
  • Congestion management, which helps to prevent network bottlenecks and ensure that all users have access to the resources they need.

In terms of PoE, it supports PoE+ which means it can provide up to 30 watts per port, so it can power devices like IP phones and wireless access points.

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 configurations 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 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.
