Security is a paramount concern in modern networking, and the Cisco WS-C3850-24T-E doesn't disappoint in this aspect. The switch is equipped with advanced security features to safeguard the integrity and confidentiality of data. This includes features such as access control lists (ACLs), secure boot, and 802.1X authentication, providing a robust defense against unauthorized access and potential security threats.

In addition to its performance capabilities, the Cisco WS-C3850-24T-E is designed with energy efficiency in mind. The switch incorporates energy-saving features such as the Energy Efficient Ethernet (EEE) standard, which automatically reduces power consumption during periods of low network activity. This not only contributes to environmental sustainability but also results in cost savings for organizations by minimizing power consumption.

Quality of Service (QoS) is a critical aspect of networking, especially in environments where different types of traffic coexist. The Cisco WS-C3850-24T-E supports QoS features, allowing organizations to prioritize and allocate bandwidth based on the specific requirements of different applications or services. This ensures optimal performance for mission-critical applications and a seamless user experience across the network.

The WS-C3850-24T-E Cisco Catalyst 3850 is a scalable and secure networking solution that provides a range of features to help ensure the reliability and security of your network.

Scalability: The switch is designed to support a large number of users and devices, making it a great choice for growing networks. It supports a variety of uplink options, including 1 Gigabit Ethernet and 10 Gigabit Ethernet, so you can easily expand your network as needed. The switch also supports Cisco StackWise-480 technology, which allows for high-performance stacking of up to 9 switches and provides resiliency. This allows for a more efficient use of resources and eliminates the need for multiple devices.

Security: The switch provides advanced security features to help protect your network from threats. Some of these features include:

• Cisco TrustSec: This feature provides identity-based security by allowing you to assign security policies to users, devices, and applications based on their identity, rather than their IP address.
• Cisco Identity Services Engine (ISE): This feature provides network access control by allowing you to authenticate users and devices before granting them access to the network.
• Advanced threat defense: The switch is equipped with advanced threat defense features such as Cisco StackWise-480 technology, which allows for high-performance stacking of up to 9 switches and provides resiliency.
• Advanced Security Features: The switch provides advanced security features such as Access Control Lists (ACLs), Network Admission Control (NAC), Cisco TrustSec, and 802.1x Authentication which ensures the security of the network.

The WS-C3850-24T-E Cisco Catalyst 3850 is a Layer 3 switch that provides advanced routing capabilities to help ensure efficient and reliable network traffic flow. Some of its key routing capabilities include:

• IP routing: The switch supports a variety of routing protocols, including static routing, Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway Protocol (BGP) which enables it to route traffic between different subnets and VLANs within the network.
• Quality of Service (QoS): The switch provides advanced QoS features such as class-based weight fair queuing (CBWFQ), low-latency queuing (LLQ), and Weighted Random Early Detection (WRED) which helps in providing better QoS and controlling the congestion.
• Access Control Lists (ACLs): The switch supports ACLs, which allow you to filter traffic based on a variety of criteria, such as source and destination IP address, port number, and protocol. This helps to secure the network by allowing or denying traffic based on specific rules.
• Virtual Routing and Forwarding (VRF): The switch supports VRF which allows for the creation of multiple routing tables within the same device, which helps to isolate different parts of the network and improve security.
• Multicast Routing: The switch supports multicast routing protocols such as Protocol Independent Multicast (PIM) and Internet Group Management Protocol (IGMP) which enables it to efficiently route multicast traffic.

The WS-C3850-24T-E Cisco Catalyst 3850 provides several power options and redundancy features to help ensure that your network stays up and running even in the event of a power failure.

Power Options: The switch supports both AC and DC power inputs, allowing you to choose the most appropriate power source for your network. It also supports PoE (Power over Ethernet), which allows you to power devices such as IP phones and wireless access points directly over the Ethernet cable, eliminating the need for separate power supplies. Additionally, it supports Cisco StackPower technology, which allows you to share power resources between multiple switches in a stack, providing additional redundancy and flexibility.

Redundancy: The switch provides several redundancy features to help ensure that your network stays up and running in the event of a power failure or other issues.

• Redundant Power Supply: The switch can be equipped with an optional redundant power supply, which provides a backup power source in case of a failure of the primary power supply.
• StackWise-480: This technology allows for high-performance stacking of up to 9 switches and provides resiliency in case one of the switches fails, the other will take over.
• Hot Standby Router Protocol (HSRP): This protocol allows for the redundancy of the default gateway, so in case one of the switches fails, the other will take over the role.
• Link Aggregation Control Protocol (LACP): This protocol allows for the bundling of multiple physical ports together to form a single logical link, providing redundancy in case one of the physical links fails.
