Product Review

The Cisco 76-ES+T+XC-40G provides versatile connectivity options with its 20 1GE ports and 2 10GE ports, catering to varied network demands. However, its low queue type might limit performance under high traffic conditions, potentially affecting data throughput. It supports a high forwarding rate and extensive Layer 2 and Layer 3 forwarding capabilities, making it suitable for deployment in environments requiring efficient data packet processing.


The Cisco 76-ES+T+XC-40G module is designed to enhance the capabilities of Cisco 7600 series routers, offering a mix of 1 Gigabit Ethernet (GE) and 10 Gigabit Ethernet (GE) ports to accommodate a variety of network requirements. This module is compatible with all models in the Cisco 7600 series, with the exception of the Cisco 7603 router, ensuring a wide range of deployment options for network administrators. This product features 22 ports in total, with a combination of port types to support both 1GE and 10GE connections. Specifically, it includes 20 ports dedicated to 1GE and 2 ports designed for 10GE. This configuration allows for flexible connectivity options, catering to both standard and high-speed networking needs. The module is equipped with a Low Queue Type and supports a Distributed Forwarding Card (DFC3CXL), enhancing its performance and efficiency in handling network traffic. Furthermore, it is designed to operate with Cisco IOS version 15.2(2)S or later, ensuring compatibility with the latest software features and security updates. Key hardware specifications include:
  • Power consumption of 427 W, optimizing energy use while maintaining high performance.
  • A forwarding rate of 59.52 million packets per second (Mpps), enabling efficient data transmission across the network.
  • Round-Trip-Time (RTT) Buffer of 200 ms, ensuring smooth and reliable data flow even in high-demand scenarios.
Additionally, the module supports an extensive number of queues per 10GE port, with a maximum of 32K, allowing for sophisticated traffic management and prioritization. This capability is essential for networks that handle a large volume of data and require granular control over packet forwarding. In terms of forwarding capacity, the module excels with over 40 Mpps for Layer 3 or Layer 4 forwarding and up to 125 Mpps for Layer 2 forwarding. This high performance ensures that the network can efficiently process a large amount of data without bottlenecks, maintaining optimal operation even under heavy loads. The boot disk of the module is equipped with 512 MB of storage, providing ample space for the operating system and additional software components. This storage capacity ensures that the module can be updated and maintained with the latest software versions without storage constraints. In summary, the Cisco 76-ES+T+XC-40G module is a powerful addition to the Cisco 7600 series routers, offering a balance of 1GE and 10GE ports along with advanced features for efficient network management and data forwarding. Its compatibility with Cisco IOS 15.2(2)S or later, combined with its high performance and flexibility, makes it an ideal choice for network administrators looking to enhance their network infrastructure.
