Features

The Cisco WS-C3850-24P-S Ethernet Switch offers several key features that make it a powerful networking solution for businesses. These features include Power over Ethernet (PoE), stackable capability, and Layer 3 routing.

Power over Ethernet (PoE)

The PoE feature allows the switch to deliver both data and power to PoE-enabled devices such as IP phones, wireless access points, and IP cameras. This eliminates the need for separate power sources for these devices, simplifying installation and reducing costs. With PoE, businesses can easily deploy network devices in locations where power outlets are not readily available.

Stackable

The stackable capability of the Cisco WS-C3850-24P-S Ethernet Switch enables users to connect multiple switches together to create a single logical unit. This provides increased scalability and simplifies network management. By stacking switches, businesses can easily expand their network as needed without having to manage multiple individual switches.

Layer 3 Routing

The Layer 3 routing feature allows the switch to route traffic between different VLANs (Virtual Local Area Networks) within the network. This enhances network performance by reducing broadcast traffic and improving overall network efficiency. Layer 3 routing also enables the implementation of advanced network security measures and facilitates better traffic control.

Management

The management capabilities of the Cisco WS-C3850-24P-S Ethernet Switch are designed to provide users with easy and efficient control over their network infrastructure. The switch offers web-based management, command line interface (CLI), and Simple Network Management Protocol (SNMP) support.

Web-Based Management

The web-based management interface allows users to access and configure the switch using a web browser. It provides a user-friendly graphical interface that simplifies network management tasks such as configuring VLANs, monitoring network performance, and managing security settings. Web-based management is particularly useful for users who are not familiar with command line interfaces.

Command Line Interface (CLI)

The CLI provides advanced users with a powerful tool for configuring and managing the switch. It allows for precise control over network settings and offers a wide range of configuration options. The CLI is essential for network administrators who prefer the flexibility and granularity of command line interfaces.

Simple Network Management Protocol (SNMP)

SNMP support enables the switch to be monitored and managed remotely using network management software. It provides real-time monitoring of network performance and allows for proactive troubleshooting and maintenance. SNMP also facilitates centralized network management, making it easier to manage a large number of switches in a complex network environment.

Security

The Cisco WS-C3850-24P-S Ethernet Switch offers robust security features to protect the network and data from unauthorized access. Key security features include 802.1X authentication and MACsec encryption.

802.1X Authentication

802.1X authentication provides a mechanism for controlling network access based on user identity. It ensures that only authorized devices and users can connect to the network, preventing unauthorized access and potential security breaches. 802.1X authentication enhances network security by requiring users to provide valid credentials before accessing network resources.

MACsec Encryption

MACsec (Media Access Control Security) encryption provides secure communication between network devices by encrypting data packets at the MAC layer. It protects against unauthorized interception and tampering of data, ensuring the confidentiality and integrity of sensitive information. MACsec encryption is particularly important in environments where data privacy is crucial, such as financial institutions or healthcare organizations.

Advanced Security Measures

In addition to 802.1X authentication and MACsec encryption, the Cisco WS-C3850-24P-S Ethernet Switch offers a range of advanced security measures. These include access control lists (ACLs), port security, and secure management protocols such as SSH (Secure Shell) and HTTPS (Hypertext Transfer Protocol Secure). These features provide additional layers of security to protect the network from internal and external threats.

Uplink Ports

The Cisco WS-C3850-24P-S Ethernet Switch is equipped with 4 x 1G SFP (Small Form-Factor Pluggable) uplink ports. These ports provide high-speed connectivity options for connecting the switch to other network devices or uplinking to higher-level switches or routers.

High-Speed Connectivity

The 1G SFP uplink ports offer high-speed connectivity, allowing for fast data transfer between the switch and other network devices. This ensures smooth and efficient communication within the network, minimizing latency and improving overall network performance.

Flexible Network Design

The presence of uplink ports gives users the flexibility to design and expand their network infrastructure according to their specific requirements. The uplink ports enable users to connect the switch to different types of devices such as routers, switches, or servers, depending on the network topology and needs.

Redundancy and Resilience

The 4 x 1G SFP uplink ports also provide redundancy and resilience for the network. Users can configure these ports in a redundant configuration, ensuring that if one port fails, the network traffic can automatically be routed through another port without any disruption. This helps in maintaining network uptime and ensuring continuous operation of critical business applications.
