Product Review

The Cisco WS-SUP720-3BXL offers high performance with IPv4 routing capabilities up to 400 Mpps and supports up to 1,000,000 IPv4 routes, making it suitable for large-scale networks. However, its limitation to 2 Gigabit uplinks may restrict throughput in environments requiring higher bandwidth connections. Additionally, the product supports a wide range of features such as hardware-assisted NAT, GRE, and up to 1024 VRFs, enabling versatile network configurations and efficient traffic management.


The Cisco WS-SUP720-3BXL is a high-capacity network processing engine designed to meet the demands of high-performance, enterprise, and service provider networks. This product delivers advanced features and scalability for a wide range of applications, including high-speed WAN uplink interfaces and IPv4/IPv6 routing. At the core of the WS-SUP720-3BXL are its powerful hardware specifications, designed to enhance network efficiency and security. It supports up to 2 Gigabit Ethernet uplinks, providing a solid foundation for high-speed connectivity and data transfer. The device is capable of IPv4 routing in hardware up to 400 Mpps (million packets per second) and IPv6 routing up to 200 Mpps, ensuring rapid data processing and transmission across the network. For Layer 2 bridging in hardware, it also reaches speeds up to 400 Mpps, facilitating quick data exchange and connectivity within local area networks. Key specifications include: - VRFs: Support for up to 1024 VRFs, allowing for a total of up to 1,000,000 routes per system. This feature is crucial for network segmentation and improving security and traffic management. - NAT: Hardware-assisted Network Address Translation enhances network security and address management without compromising performance. - GRE: Generic Routing Encapsulation in hardware, enabling the encapsulation of a wide variety of network layer protocols inside point-to-point links. The WS-SUP720-3BXL boasts a MAC address table capacity of 64,000 entries, supporting large-scale network operations without performance degradation. The routing capacity is extensive, with support for up to 1,000,000 IPv4 routes and 500,000 IPv6 routes, making it well-suited for large and complex network environments. Netflow entries are supported up to 256,000, providing comprehensive network monitoring and analysis capabilities. The device also supports 32K dedicated Access Control Entries (ACEs) for Layer-3 classification and marking for Quality of Service (QoS), ensuring prioritization of critical network traffic. For traffic management and security, the WS-SUP720-3BXL includes features such as: - Aggregate and flow-based rate-limiting: Offering 1023 aggregate traffic rate-limiting policers and a flow-based rate-limiting method per source address, destination address, or full flow, allowing for precise control over network traffic. - Security ACL entries: Up to 32K, along with 128K reflexive ACLs, enhancing network security and access control. It further supports uRPF (Unicast Reverse Path Forwarding) check in hardware for up to 6 paths, aiding in the mitigation of network spoofing attacks. The CPU rate limiters include 10 special case rate limiters plus control plane policing, providing additional layers of security and traffic management. The device allows for the application of unique ACLs to a maximum of 4000 interfaces, ensuring detailed access control and security across the network. This capability is complemented by MAC ACLs featuring per-port/per VLAN granularity and ACE counters for comprehensive monitoring and control of network access. In summary, the Cisco WS-SUP720-3BXL is engineered to deliver exceptional performance, scalability, and security for demanding network environments. Its advanced hardware capabilities make it an ideal solution for enterprises and service providers seeking to optimize their network operations and ensure robust data protection and traffic management.
