More Information about Cisco Managed Switch

The performance of a Cisco 12-port switch will depend on a number of factors, including the specific model of the switch, the networking standard it supports, the number of devices connected to it, and the presence of any physical obstructions.

In general, Cisco 12-port switches are capable of delivering fast networking speeds and have a number of advanced features that can help to improve their performance and reliability. These features may include things like Quality of Service (QoS), which allows you to prioritize certain types of traffic, and security features, such as encryption and authentication, to protect your network from unauthorized access.

If you are considering using a Cisco 12-port switch in your network, it is always a good idea to test its performance in your environment to ensure that it meets your needs. You can do this by connecting devices to the switch and measuring the data transfer speeds and stability of the connection.

High Availability and Redundancy Options

The WS-C3850-12XS-S Cisco Catalyst 3850 12 Ports SFP+ Layer 3 Switch is designed with high availability and redundancy options in mind to help ensure that the network remains operational even in the event of a failure. Some of the key features that contribute to this include:

  • StackWise-480 Technology: The switch supports StackWise-480 technology, which allows multiple switches to be connected together and managed as a single logical unit. This provides increased scalability and resiliency, as well as allowing for the use of a Virtual Switching System (VSS) for active/active redundancy.
  • Flexible NetFlow (FNF): The switch supports Flexible NetFlow (FNF) which allows the switch to keep track of the flow of traffic on the network and to take appropriate actions in case of a failure of one of the switches.
  • Virtual Router Redundancy Protocol (VRRP): The switch supports Virtual Router Redundancy Protocol (VRRP) which allows two or more routers to work together to present the appearance of a single virtual router to the hosts on a LAN. This can provide redundancy in the event of a failure of one of the routers.
  • Link Aggregation Control Protocol (LACP): The switch supports Link Aggregation Control Protocol (LACP) which allows multiple physical links to be bundled together to form a single logical link. This can provide increased bandwidth and redundancy in case of a failure of one of the links.
  • Rapid Spanning Tree Protocol (RSTP): The switch supports Rapid Spanning Tree Protocol (RSTP) which allows multiple switches to be connected together and managed as a single logical unit. This can provide redundancy in the event of a failure of one of the switches.

All those features provide a strong layer of high availability and redundancy options to the WS-C3850-12XS-S Cisco Catalyst 3850 12 Ports SFP+ Layer 3 Switch and help to ensure that the network remains operational even in the event of a failure, and minimize the risk of network downtime. Additionally, the switch supports a variety of redundancy protocols such as Hot Standby Router Protocol (HSRP) and Gateway Load Balancing Protocol (GLBP), which also work to ensure network availability.

Cisco 12 Ports Ethernet Switch

A Cisco 12 ports Ethernet switch is a networking device that is designed to connect devices together on a local area network (LAN). It has 12 Ethernet ports, which allow you to connect devices such as computers, servers, and printers to the switch.

The switch is designed to receive incoming packets of data and forward them to the appropriate destination based on the destination address of the packet. This allows devices on the LAN to communicate with each other and share resources, such as printers and files.

Some of the key features of a Cisco 12 ports Ethernet switch might include:

  • High-speed performance: The switch is designed to deliver fast networking speeds, often up to 10 Gbps (gigabits per second) per port.
  • Advanced features: The switch may have a number of advanced features, such as Quality of Service (QoS), security features, and virtualization support, to improve its performance and functionality.
  • Easy to manage: The switch may have a user-friendly interface and a variety of management tools to make it easy to install and configure.
  • Reliability: The switch is designed to be reliable and able to withstand the rigors of daily use.

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.
