Product Review

The Cisco WS-C4900M offers a switch capacity of 320 Gbps and supports up to 250 Mpps throughput for IPv4, ensuring efficient data handling for high-demand networks. However, the model presents limitations in IPv6 performance with a throughput of only 125 Mpps, and its hardware, including a 1.3 GHz CPU and 512 MB SDRAM, may struggle under the load of modern, intensive applications. With support for a maximum of 24 10 Gigabit Ethernet ports and 32 Gigabit Ethernet (Fiber) ports, it provides flexible connectivity options, but the requirement for Cisco IOS Software Release 12.2(40)XO or later for operation could necessitate updates for some users.


The Cisco WS-C4900M is a high-performance, versatile switch designed to meet the demands of mid-sized enterprise, data center, and service provider networks. With a switch capacity of 320 Gbps and a remarkable throughput of 250 million packets per second (Mpps) for IPv4 traffic and 125 Mpps for IPv6 traffic, this switch ensures efficient handling of network traffic, supporting the seamless operation of applications and services. The device's hardware is built to accommodate IPv6, enabling future-proof network expansion and compatibility. Measuring at a compact 2 rack units (RU) in height, the Cisco WS-C4900M is designed for space efficiency while still offering ample capacity and performance. It features two modular half-card slots, allowing for customization and scalability. Users can maximize the switch's potential by utilizing up to 24 10 Gigabit Ethernet ports or 32 Gigabit Ethernet (fiber) ports, depending on their network requirements. The switch supports 8x2 10 Gigabit Ethernet optics for uplink connections, providing high-speed connectivity options for demanding applications. It also offers a variety of software services including IP Base and Enterprise Services options, facilitating advanced multilayer switching capabilities. Key hardware specifications include a shared buffer of 16 MB, a 1.3 GHz CPU, and 512 MB of SDRAM. This hardware foundation supports the management and processing of extensive data volumes, ensuring reliable performance under varied network conditions. - Active VLANs supported by the device reach up to 4,096, allowing for extensive network segmentation and improved security. - The switch can handle up to 56,000 multicast entries for IPv4 and 28,000 for IPv6, enabling efficient multicast traffic distribution. - Security and Quality of Service (QoS) hardware entries cap at 128,000, showcasing the switch's ability to maintain high levels of network security and traffic prioritization. Additional features enhancing the switch’s utility include support for up to 55,000 MAC addresses, enabling the device to interface with a large number of networked devices without compromising performance. It also supports the Spanning Tree Protocol with up to 10,000 instances and 4,000 switched virtual interfaces, further emphasizing its capability to manage complex network architectures. For network monitoring and analysis, the Cisco WS-C4900M provides Switched Port Analyzer (SPAN) functionality with 8 ingress and 8 egress ports, aiding in traffic diagnosis and troubleshooting. The presence of a USB port and compact flash memory support facilitates easy system upgrades and file transfers, ensuring the switch remains up-to-date with the latest features and security patches. The system reset button adds a layer of convenience for quick troubleshooting and reset procedures. To operate, the switch requires Cisco IOS Software Release 12.2(40)XO or later, ensuring compatibility with modern network protocols and services. Designed to function optimally within a temperature range of 0 °C to 40 °C, the Cisco WS-C4900M is suited for deployment in a variety of environments, delivering reliable performance under different operational conditions.
