Product Review

The Cisco WS-C3750X-48P-L switch offers 48 10/100/1000 Ethernet PoE+ ports in a compact 1 RU form factor, providing efficient space utilization and power supply capacity of 715 W, suitable for high-density PoE deployments. With a switching fabric of 160 Gbps and a forwarding rate of 101.2 Mpps, it supports high-speed data processing and multiple layers, but the limited DRAM of 256 MB and flash memory of 64 MB may constrain advanced applications and extensive routing tables. Despite these limitations, the switch's support for up to 1005 VLANs and advanced features like QoS and security ACEs make it a versatile choice for medium-scale enterprise networks.


The Cisco WS-C3750X-48P-L is a stackable 10/100/1000 Ethernet PoE+ switch designed to provide high efficiency and scalability for diverse networking environments. This model comes equipped with 48 ports, enabling significant connectivity options for various devices and applications. With a 1 rack unit (RU) form factor, it is engineered to fit seamlessly into standard data center architectures, optimizing space without sacrificing performance. This switch is powered by a 715 W AC power supply, ensuring sufficient power for itself and PoE+ devices connected to it, delivering enhanced energy efficiency across the network. The device operates on the LAN Base feature set, which provides a foundational suite of networking features suitable for a wide range of applications. The hardware specifications of the WS-C3750X-48P-L include a switching fabric capacity of 160 Gbps and a forwarding rate of 101.2 million packets per second (Mpps), highlighting its capability to handle substantial data traffic efficiently. The device is built with 256 MB of DRAM and 64 MB of flash memory, supporting the system's operation and allowing for firmware and configuration storage. In terms of scalability, the WS-C3750X-48P-L supports a comprehensive range of VLANs, with a total of 1005 VLANs and 4K VLAN IDs, enhancing network segmentation and security. The switch can manage up to 1K total switched virtual interfaces (SVIs), facilitating efficient routing between VLANs. For networks requiring extensive multicast and unicast routing, the device supports 1K IGMP groups, 1K multicast routes, and 8K unicast routes, ensuring broad compatibility and flexibility in complex network environments. The switch's capability to process jumbo frames up to 9216 bytes makes it suitable for high-performance computing and storage networks, where large frame sizes can significantly improve efficiency. With the capacity to handle 468 routed ports per 3750-X stack, 6K MAC addresses, and direct and indirect routing for thousands of hosts, this switch is designed for scalability and high-density deployments.
