Product Review

The Cisco WS-C3750X-12S-S switch offers 12 stackable GE SFP Ethernet ports, providing flexibility for a variety of network connections. Its high switching fabric capacity of 160 Gbps and forwarding rate of 35.7 Mpps enable efficient data processing and throughput. However, the limitation of 1005 VLANs and 512 MB DRAM may restrict its performance in highly dense network environments or in scenarios requiring extensive VLAN segmentation and routing information storage.


The Cisco WS-C3750X-12S-S is a stackable Gigabit Ethernet switch designed to enhance productivity by enabling applications such as IP telephony, wireless, and video for a borderless network experience. This switch is equipped with 12 SFP Ethernet ports, allowing for flexible fiber optic connections. It operates with a 350 W AC power supply and fits in a 1 RU form factor, making it suitable for compact spaces in data centers or network closets. At the core of its performance, the switch boasts a forwarding rate of 35.7 Mpps (million packets per second) and a switching fabric capacity of 160 Gbps, ensuring efficient handling of data traffic across the network. It is powered by 512 MB of DRAM and 128 MB of flash memory, facilitating smooth operation and storage of the firmware and network configurations. The WS-C3750X-12S-S comes with an IP Base software feature set, supporting essential Layer 2 and basic Layer 3 routing features. It is capable of managing multiple layers of network architecture, providing versatility in deployment. The switch supports up to 1005 total VLANs with 4K VLAN IDs and 1K total SVIs (Switched Virtual Interfaces), allowing for extensive network segmentation and efficient management of broadcast domains. For networks requiring extensive data processing, this switch supports jumbo frames up to 9216 bytes, enhancing the efficiency of large data transfers. The capacity for routed ports per 3750-X stack is 468, indicating the switch's ability to manage a large number of routed interfaces in a stacked configuration. Security and network integrity are ensured with the support for 6K MAC addresses, 1K IGMP groups, 1K multicast routes, and 8K unicast routes. Additionally, the switch can handle directly connected hosts up to 6K, with 2K indirect routes, offering substantial capacity for routing and host management. Quality of Service (QoS) is a priority, with 0.5K QoS classification Access Control Entries (ACEs) and 1K security ACEs, ensuring prioritized traffic flow and secure access control throughout the network. The WS-C3750X-12S-S is designed for longevity and reliability, with a Mean Time Between Failure (MTBF) of 194,224 hours, indicating a high level of durability and operational stability. Its dimensions are 1.75 x 17.5 x 18.0 inches, providing a compact solution that does not compromise on power or functionality.
  • Switching Fabric: 160 Gbps
  • DRAM: 512 MB
  • Flash Memory: 128 MB
In summary, the Cisco WS-C3750X-12S-S is a powerful, scalable, and reliable networking switch that meets the demands of evolving network environments. It provides efficient data processing, extensive feature support, and robust security controls, making it an ideal choice for organizations looking to enhance their network infrastructure.
