A distinctive feature of this switch is its Power Over Ethernet capability. It can deliver power to connected devices such as IP phones, wireless access points, and surveillance cameras through Ethernet cables, eliminating the need for separate power sources.

With its management capabilities, administrators can efficiently control and monitor the network. The switch operates at Layer 4 of the OSI model, offering advanced functionalities for traffic prioritization and enhanced security measures.

The WS-C3750E-24PD-S is stackable, allowing multiple switches to be interconnected and managed as a single unit. This stacking capability enhances scalability and simplifies network management in larger setups.

The switch is equipped with two uplink ports, enabling connections to other network devices or to connect multiple switches together, expanding the network capacity and ensuring redundancy for critical links.

Enterprise Networks

In enterprise environments, the WS-C3750E-24PD-S finds extensive use due to its robustness and scalability. It caters to the demands of large-scale networks by efficiently handling data traffic and providing reliable connectivity.

Powering Network Devices

The PoE capability of this switch makes it an ideal choice for environments where devices like IP cameras, VoIP phones, and wireless access points require power through the Ethernet connection. It simplifies installation and reduces cable clutter.

Enhanced Network Management

Administrators benefit from the manageability features of the switch, allowing them to monitor, configure, and optimize network performance. The Layer 4 capabilities enable traffic prioritization for critical applications.

With its multitude of ports and PoE capability, this switch simplifies network connectivity by providing power and data transfer over a single Ethernet cable, reducing complexity and costs.

The Layer 4 capabilities and advanced management features contribute to optimized network performance, ensuring smooth and efficient data transfer even in high-traffic environments.

The stackable design and uplink ports enable easy expansion of the network, offering scalability and flexibility to adapt to the evolving needs of the organization.

The ME-3400-24TS-D Cisco 3400-24TS 24-Ports Ethernet Access Layer 3 Switch is designed for scalable and secure networking. Some of the features that contribute to this include:

• Layer 3 capabilities: The switch supports Layer 3 routing protocols such as OSPF and RIP, which allow you to create a more scalable and efficient network by dividing it into smaller, more manageable subnets.
• VLANs: The switch supports VLANs, which allow you to segment your network into different logical groups. This can help to improve network security by isolating different types of network traffic and can also help to improve network performance by reducing broadcast traffic.
• Quality of Service (QoS): The switch supports advanced QoS capabilities, which allow you to prioritize network traffic based on different criteria such as IP address, MAC address, and port number. This helps to ensure that critical network traffic is delivered with minimal delay and interruption.
• Access Control Lists (ACLs): The switch supports ACLs, which allow you to define security policies that control who can access the network and what types of traffic are allowed. This can help to improve network security by blocking unauthorized access and controlling the flow of traffic.
• Link Aggregation Control Protocol (LACP): LACP allows you to bundle multiple physical ports together to form a single logical link. This can help to increase the bandwidth available to your network and improve network performance, while also providing redundancy in case of a failure.
• Security features: The switch supports advanced security features such as IEEE 802.1X port-based authentication and RADIUS, TACACS+, and Kerberos which can help to prevent unauthorized access to the network and protect against malicious attacks.

The WS-C3750E-24PD-S Cisco Catalyst 3750-E 24-Ports Ethernet Switch is a reliable network device that is widely used in enterprise environments. This switch is part of the Cisco Catalyst 3750-E series, which is known for its energy efficiency and advanced security features.

The 3750-E series also supports StackWise technology, which allows multiple switches to be connected together to function as a single, unified device for increased network scalability and redundancy. This provides a high level of availability for the network.

In addition, the switch supports advanced Quality of Service (QoS) features, which allow for the prioritization of network traffic to ensure that mission-critical applications receive the bandwidth they need.
