CDB-3850-24U-L Cisco Digital Building Catalyst 3850 24 Ports Upoe Bundle Switch | Refurbished

The Cisco Digital Building Catalyst 3850 24 Ports UPOE Bundle Switch (CDB-3850-24U-L) is designed to maximize switch uptime and reliability in digital building environments. This is achieved through a number of features and technologies that work together to ensure that the switch is always available and functioning properly.

One key feature that contributes to the switch’s uptime is its redundant power supply and fan modules. This ensures that if one power supply or fan fails, the switch can continue to operate without interruption. Additionally, the switch has a built-in self-healing mechanism that automatically detects and corrects software and hardware faults, minimizing the likelihood of downtime.

Another important aspect of the switch’s reliability is its ability to support high-density PoE (Power over Ethernet) and UPOE (Universal PoE) for powering devices such as IP phones, wireless access points, and cameras. This allows for a large number of devices to be connected to the switch without the need for additional power sources, reducing the potential for power-related issues that could lead to downtime.

The switch also supports advanced security features, such as Cisco Identity Services Engine (ISE) and TrustSec, that help to protect the network from potential security threats. This adds an additional layer of protection to the network, reducing the risk of unauthorized access or data breaches.

Maximize Network Performance of 3850 Series Switch

The Cisco Digital Building Catalyst 3850 24 Ports Upoe Bundle Switch (CDB-3850-24U-L) is a powerful and versatile network device designed to maximize network performance in digital building environments. It is equipped with 24 UPOE ports, which allow for the simultaneous delivery of both power and data to connected devices. This feature eliminates the need for separate power supplies and makes deployment and management of connected devices much simpler.

The switch also features a highly scalable and resilient network architecture that can support a wide range of network topologies and use cases. It supports advanced features such as Quality of Service (QoS), Link Aggregation Control Protocol (LACP), and Virtual Local Area Networks (VLANs) to ensure optimal network performance and security.

The switch also includes a range of advanced security features, including access control lists (ACLs), secure shell (SSH) and Simple Network Management Protocol (SNMP) to protect against unauthorized access and malicious attacks. Additionally, the switch supports Cisco’s Network Assurance Engine (NAE) which provides real-time monitoring and troubleshooting capabilities to ensure optimal network performance and availability.

Quality of Service (QoS) and Traffic Management

The Cisco Digital Building Catalyst 3850 24 Ports UPOE Bundle Switch (CDB-3850-24U-L) is a high-performance network switch that is designed for use in large, multi-tenant buildings and other large-scale digital building environments. One of the key features of this switch is its support for Quality of Service (QoS) and traffic management, which allows administrators to prioritize different types of network traffic and ensure that critical applications and services receive the bandwidth and resources they need to operate effectively.

Quality of Service (QoS) refers to the ability of a network to provide different levels of service to different types of traffic based on their importance or priority. This is accomplished by using various QoS mechanisms such as traffic shaping, bandwidth allocation, and packet prioritization.

The CDB-3850-24U-L supports a wide range of QoS features, including:

• Class-Based Weighted Fair Queuing (CBWFQ): This mechanism allows administrators to assign different priority levels to different types of traffic based on their importance. For example, critical applications such as VoIP and video conferencing can be assigned a higher priority than less critical traffic such as email and web browsing.
• Low Latency Queuing (LLQ): This mechanism helps to minimize the delay and jitter experienced by real-time applications such as VoIP and video conferencing. It does this by prioritizing packets from these applications and ensuring that they are sent through the network as quickly as possible.
• Quality of Service Marking (QoS Marking): This feature allows administrators to mark packets with a specific priority level, which is then used to determine how the packets are handled by the network.
• Traffic Shaping: This feature allows administrators to limit the amount of bandwidth that a specific type of traffic can use. This can be useful for preventing specific types of traffic from consuming too much bandwidth and causing congestion on the network.
• Bandwidth Allocation: This feature allows administrators to allocate a specific amount of bandwidth to different types of traffic. This can be useful for ensuring that critical applications and services receive the resources they need to operate effectively.

In addition to these QoS features, the CDB-3850-24U-L also supports a range of traffic management features, such as:

• Access Control Lists (ACLs): These lists allow administrators to specify which types of traffic are allowed on the network and which are blocked. This can be useful for securing the network and preventing unauthorized access.
• Port Security: This feature allows administrators to specify which devices are allowed to connect to specific ports on the switch. This can be useful for preventing unauthorized access and ensuring that only authorized devices are able to connect to the network.
• Storm Control: This feature allows administrators to limit the amount of broadcast, multicast, or unknown unicast traffic that is allowed on the network. This can be useful for preventing network storms and ensuring that the network remains stable and responsive.
