Product Review

The Cisco WS-C4948-10GE-S offers a solid switching capacity of 136 Gbps and a throughput of 102 Mpps, catering well to high-demand network environments. However, its limitation to only two 10 Gigabit Ethernet ports may restrict scalability in densely populated networks. Additionally, the switch provides a comprehensive IP Base and Enterprise Services for Layer 3 routing, including support for IPv6 in software, but its 256 MB of SDRAM and 666 MHz CPU may not meet the needs of future advanced applications and services.


The Cisco WS-C4948-10GE-S is a high-performance switch designed for data center networks. It features 48 10 Gigabit Ethernet ports for high-speed connectivity and efficient data transfer across the network. This device is equipped with a single AC power supply and a fan tray to ensure reliable operation and optimal cooling under various network loads. This model supports a range of software images to cater to different networking needs. The LAN Base Image offers basic Layer 2 functionality, while the IP Base Image introduces standard Layer 3 capabilities, including Routing Information Protocol Version 1 and 2 (RIPv1, RIPv2), static routes, and Enhanced Interior Gateway Routing Protocol (EIGRP) Stub routing. For more advanced network requirements, the Enterprise Services Image provides an enhanced Layer 3 feature set, including Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS), EIGRP, Border Gateway Protocol (BGP), AppleTalk, and Internetwork Packet Exchange (IPX) Software Routing. Key hardware specifications of the Cisco WS-C4948-10GE-S include: - A switching capacity of 136 Gbps, allowing for efficient handling of network traffic. - A throughput rate of 102 million packets per second (Mpps), ensuring quick data processing. - Support for IPv6 in software, facilitating future network expansions and compatibility with new internet protocols. Other notable features of this switch include: - A compact form factor of 1 rack unit (RU), making it suitable for space-constrained environments. - The capability to support a maximum of 2 10 Gigabit Ethernet ports, providing options for network uplink or aggregation. - The lack of support for the Cisco TwinGig Converter Module, focusing on direct 10 Gigabit Ethernet connectivity. From a technical standpoint, the WS-C4948-10GE-S is built to handle demanding network environments. It comes with a shared buffer of 16 MB and is powered by a 666 MHz CPU with 256 MB of SDRAM, which helps in managing the extensive feature set and maintaining high performance levels. The switch supports up to 4096 active VLANs, allowing for extensive network segmentation and security configurations. It can also handle up to 28,000 Layer 3 multicast entries and 16,000 Layer 2 multicast entries, supporting efficient distribution of data across the network. The device is capable of storing up to 55,000 MAC addresses, facilitating large-scale network connectivity without compromising on speed or efficiency. Furthermore, it supports up to 10,000 Spanning Tree Protocol instances, ensuring robust network redundancy and reliability. In summary, the Cisco WS-C4948-10GE-S is engineered to meet the needs of medium to large-scale enterprise networks, offering high-speed connectivity, extensive feature support, and reliable performance. Its hardware specifications make it an ideal choice for organizations looking for a switch that can accommodate current and future networking requirements.
