Product Review

The Cisco WS-X45-SUP7-E offers a centralized switching capacity of 848 Gbps and a per-slot capacity of 48 Gbps, ensuring high performance for demanding network environments. However, its throughput for IPv6 is half that of IPv4, which might limit performance in dual-stack deployments. With support for up to 4,094 active VLANs and extensive hardware entries, it is well-suited for large-scale operations, though the initial 2 GB of SDRAM, upgradeable to 4 GB, may necessitate an upgrade for optimal performance in memory-intensive configurations.


The Cisco WS-X45-SUP7-E is a high-performance supervisor engine designed to provide centralized switching capabilities, enhanced throughput, and a comprehensive suite of features aimed at optimizing network performance and reliability. This product is engineered to support demanding network environments and is equipped with advanced hardware specifications to meet the needs of complex data and processing tasks. At the core of its performance metrics, the Cisco WS-X45-SUP7-E boasts a centralized switching capacity of 848 Gbps, coupled with a per-slot switching capacity of 48 Gbps. This ensures efficient handling of data across the network, even in high-demand scenarios. The device delivers impressive throughput rates, including 250 million packets per second (Mpps) for IPv4 and Layer 2 bridging, and 125 Mpps for IPv6, facilitating swift data processing and transmission. The supervisor engine supports a substantial number of routing and service entries. It can handle up to 256,000 IPv4 routing entries and 128,000 IPv6 routing entries. For multicast routing, it initially supports 16,000 routes, which can be expanded to 32,000 with Cisco IOS XE 3.2.0 SG or later versions. This scalability ensures the network can grow without compromising on performance or reliability. Key hardware features include: - A dual-core CPU running at 1.5 GHz, backed by 64 CPU queues for efficient data processing and task management. - Standard 2 GB of SDRAM, upgradable to 4 GB, providing ample memory for complex operations and applications. - 1 GB of NVRAM, ensuring the persistence of critical configuration and state information across reboots. The WS-X45-SUP7-E supports a wide array of network standards and capacities, including:
  • 55,000 MAC addresses, facilitating extensive device connectivity.
  • 4,094 active VLANs, allowing for intricate network segmentation and management.
  • 10,000 Spanning Tree Protocol instances, enhancing network resilience and loop prevention.
Additionally, it offers up to 8 Switched Port Analyzer (SPAN) sessions for either ingress or egress traffic monitoring, aiding in network diagnostics and security. Supported by Cisco IOS XE Software Release 3.1.0 SG, this supervisor engine is designed for robust software integration and feature support. From an operational standpoint, the WS-X45-SUP7-E operates efficiently within a temperature range of 0°C to 40°C, and is designed for longevity with a mean time between failures (MTBF) of 155,241 hours. Its power rating stands at 280 W when active, indicating a balance between performance and energy consumption. In summary, the Cisco WS-X45-SUP7-E supervisor engine stands out as a powerful, efficient, and scalable solution for modern network environments. With its advanced processing capabilities, extensive entry support, and operational resilience, it is designed to meet the needs of complex, data-intensive networks, ensuring high availability, security, and performance.
