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.
