WS-C3750E-48PD-S

Key Features of the Cisco WS-C3750E-48PD-S:

1. 48 Gigabit Ethernet Ports:

   • The WS-C3750E-48PD-S is equipped with 48 x 10/100/1000 Mbps Gigabit Ethernet ports, providing high-speed, reliable connectivity to a wide range of devices, such as computers, workstations, servers, and networked devices.
   • These ports support full-duplex communication, allowing for fast and efficient data transfer.

2. Power over Ethernet (PoE):

   • The WS-C3750E-48PD-S provides Power over Ethernet (PoE) on all 48 of its Gigabit Ethernet ports. This allows you to power PoE-enabled devices (like IP phones, wireless access points, and security cameras) directly from the switch, eliminating the need for additional power supplies.
   • The total PoE power budget for the switch is 370W, which ensures the ability to deliver sufficient power to multiple PoE devices simultaneously.

3. Layer 3 Routing Capabilities:

   • The WS-C3750E-48PD-S is a Layer 3 switch, meaning it supports IP routing between different VLANs (Virtual Local Area Networks). This allows for traffic to be routed across subnets within the network, ensuring better scalability and communication.
   • It supports a variety of routing protocols such as RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and static routing. These features are essential for large-scale enterprise networks that need efficient routing and dynamic network management.

4. Cisco StackWise Technology:

   • The WS-C3750E-48PD-S supports Cisco StackWise technology, which allows multiple 3750-E Series switches to be stacked and managed as a single logical unit. This enables easy network expansion and simplified management.
   • The StackWise technology provides high-bandwidth connectivity (up to 32 Gbps) between stacked switches, offering seamless failover and high availability in case of switch failure.

5. Advanced Security Features:

   • The WS-C3750E-48PD-S offers a comprehensive set of security features to safeguard your network:
     • 802.1X Port-Based Authentication: Ensures that only authorized devices can access the network by requiring devices to authenticate before gaining access.
     • Access Control Lists (ACLs): Allows network administrators to define rules that filter traffic based on various parameters, such as IP address, protocol type, or port number.
     • Dynamic ARP Inspection (DAI): Protects against ARP spoofing attacks by ensuring only valid ARP packets are allowed on the network.
     • DHCP Snooping: Prevents unauthorized DHCP servers from assigning IP addresses on the network, which helps to mitigate man-in-the-middle attacks.
     • Private VLANs: Provides isolated communication between devices within the same VLAN, improving security by preventing devices from communicating with each other.

6. Quality of Service (QoS):

   • The WS-C3750E-48PD-S supports Quality of Service (QoS) to prioritize time-sensitive applications, such as VoIP (Voice over IP) and video conferencing.
   • This ensures that critical traffic receives the necessary bandwidth and low latency, even during network congestion, maintaining optimal performance for voice and video applications.

7. Redundancy and High Availability:

   • The WS-C3750E-48PD-S features redundant power supply (RPS) support to ensure that the switch continues to function even if the primary power supply fails.
   • The hot-swappable fan modules allow for easy replacement of fans without interrupting the network service, ensuring continuous network operation.

8. Energy Efficiency:

   • The switch is designed with energy-efficient features, including Energy Efficient Ethernet (EEE). This reduces the switch’s power consumption when network traffic is low, helping organizations save on operational costs and reduce their environmental impact.

9. Comprehensive Network Management:

   • The WS-C3750E-48PD-S runs on Cisco IOS Software, providing a comprehensive suite of management tools for configuring, monitoring, and troubleshooting the network.
   • It supports management protocols such as Simple Network Management Protocol (SNMP), Command-Line Interface (CLI), and Cisco Prime, allowing administrators to manage network performance effectively.
