WS-C3750E-24PD-S

Key Features of the Cisco WS-C3750E-24PD-S:

1. 24 Gigabit Ethernet Ports:

   • The WS-C3750E-24PD-S is equipped with 24 x 10/100/1000 Mbps Gigabit Ethernet ports, providing high-speed connectivity for devices such as computers, workstations, servers, and networked devices.
   • The Gigabit Ethernet ports ensure fast data transfer and efficient network communication, meeting the needs of modern, bandwidth-intensive applications.

2. Power over Ethernet (PoE):

   • One of the standout features of the WS-C3750E-24PD-S is its 24 PoE-enabled ports. This allows you to power IP phones, wireless access points (APs), IP cameras, and other PoE-compliant devices directly from the switch, eliminating the need for separate power adapters.
   • The total PoE power budget is 370W, allowing for power distribution to connected devices without requiring additional power infrastructure.

3. Layer 3 Routing Capabilities:

   • The WS-C3750E-24PD-S is a Layer 3 switch, meaning it supports IP routing capabilities between different VLANs (Virtual LANs), enabling seamless communication across subnets in large enterprise networks.
   • The switch supports various routing protocols such as RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and static routing, making it ideal for complex network environments where inter-VLAN routing is required.

4. Cisco StackWise Technology:

   • The WS-C3750E-24PD-S supports Cisco StackWise technology, which allows multiple switches to be stacked and managed as a single logical unit. This simplifies management and improves scalability, as you can add additional switches to the stack as your network grows.
   • With StackWise, stacked switches share a unified configuration and can operate as a single device, offering high availability and seamless failover.

5. Enhanced Security Features:

   • The WS-C3750E-24PD-S offers robust security features to protect your network from unauthorized access and attacks:
     • 802.1X Port-Based Authentication: This ensures that only authorized devices can access the network.
     • Access Control Lists (ACLs): ACLs help define rules for traffic filtering, ensuring that only legitimate traffic is allowed into the network.
     • Dynamic ARP Inspection (DAI): Prevents ARP spoofing attacks, helping to ensure the integrity of network communications.
     • DHCP Snooping: Protects against rogue DHCP servers by inspecting DHCP packets and ensuring that only trusted servers can assign IP addresses.
     • Private VLANs: Provides isolation between devices within the same VLAN, improving security and reducing the risk of broadcast storms.

6. Quality of Service (QoS):

   • The WS-C3750E-24PD-S supports advanced QoS (Quality of Service) features to prioritize traffic for mission-critical applications like VoIP and video conferencing.
   • It ensures that high-priority traffic receives the necessary bandwidth and low latency, while less important traffic can be deprioritized. This is essential for maintaining the quality of time-sensitive applications.

7. Redundancy and High Availability:

   • The WS-C3750E-24PD-S includes redundant power supply (RPS) support, ensuring that your network remains operational even if the primary power supply fails.
   • The switch also supports hot-swappable fan modules, which can be replaced without disrupting network operations, contributing to overall system availability.

8. Energy Efficiency:

   • The WS-C3750E-24PD-S is designed with energy-efficient features, including Energy Efficient Ethernet (EEE). This feature reduces power consumption during periods of low network activity, which helps to reduce operating costs and makes the switch more eco-friendly.

9. Comprehensive Network Management:

   • The WS-C3750E-24PD-S is compatible with Cisco IOS Software, which provides powerful management and configuration features for network administrators.
   • The switch supports various management protocols, including Simple Network Management Protocol (SNMP), CLI (Command-Line Interface), Cisco Prime, and Cisco Network Assistant for monitoring, troubleshooting, and managing network performance.
