Introduction to the 24 Ports Switch

The C1-WS3850-24S/K9 Cisco One Catalyst 3850 is a 24-port, stackable, fiber switch that can be managed through Cisco's Network Assurance Engine (NAE) and DNA Center. It supports a wide range of features, including advanced security, wireless, and application visibility and control. The switch also has a high-performance architecture, with up to 480 Gbps of stack throughput and 40 Gbps per-slot bandwidth. Additionally, it supports Cisco StackPower, which allows for power sharing among multiple stack members, providing redundancy and resiliency. Overall, the C1-WS3850-24S/K9 is a powerful and versatile switch that can be used in a variety of enterprise and campus network environments.

Maximizing Network Performance

There are several ways to maximize network performance on the C1-WS3850-24S/K9 Cisco One Catalyst 3850 24-Ports Manageable Stackable Fiber Switch:

  1. Utilize Quality of Service (QoS) to prioritize and control traffic flow.
  2. Implement Link Aggregation Control Protocol (LACP) to bundle multiple physical links together to form a single logical link.
  3. Use jumbo frames to increase the maximum transmission unit (MTU) size and reduce the number of packets needed to transmit large amounts of data.
  4. Configure the switch to use flow control to prevent network congestion.
  5. Monitor the switch's performance using the built-in tools and make adjustments as necessary to optimize network traffic.
  6. Upgrade the switch's firmware to the latest version for bug fixes and performance enhancements.
  7. Regularly check the switch for potential security threats and vulnerabilities.
  8. Use Cisco's Network Assurance Engine (NAE) to automatically detect and fix network issues.

It is important to note that the specific needs of your network may differ and require different steps to optimize performance.

Network connectivity

The C1-WS3850-24S/K9 Cisco One Catalyst 3850 24-Ports Manageable Stackable Fiber Switch has 24 SFP+ fiber ports that support 10 Gigabit Ethernet (10 GbE) connectivity. This allows for high-speed connectivity to other devices in the network, such as servers and storage systems.

The switch also has two 10 Gigabit Ethernet (10 GbE) uplink ports that can be used to connect to other network devices or to provide redundancy in the event of a link failure.

In addition, the switch supports stackwise technology, which allows multiple switches to be connected together and managed as a single entity. This provides a high level of redundancy and scalability for the network.

The switch also supports various protocols such as, Cisco StackWise-480, Cisco StackPower, and StackWise-Virtual, which allows for easy management and configuration of the switch.

The switch also supports advanced security features such as, IEEE 802.1X, and MACsec to secure the network and provide access control.

It is important to note that the specific requirements of your network will determine the best connectivity options for your organization. It may require consulting with a Cisco expert or a network administrator.
