Product Review

The Cisco N55-M160L3, designed for the Nexus 5596, offers enhanced Layer 3 capabilities with a performance ceiling of 160 Gbps or 240 million packets per second, meeting high-throughput demands. It supports up to 8K IPv4 Longest Prefix Match Routes, doubling with uRPF disabled, and includes 8,000 IPv4 Host Table entries and 4,000 IP Multicast Routes, although these capacities may be limiting for complex, large-scale networks. Its hot-swappable form factor and field-replaceable units ensure minimal downtime for maintenance, alongside a newer version of the Layer 3 ASIC, enhancing efficiency and reliability.


The Cisco N55-M160L3 is a cutting-edge module designed to enhance the capabilities of the Nexus 5596 platform, turning it into a comprehensive Layer 3 switch suitable for a variety of network demands. This module is notable for its hardware specifications that cater to high-performance and scalable networking requirements. At the core of the N55-M160L3's capabilities is its support for IPv4 Longest Prefix Match Routes, with a capacity of up to 8,000 routes. This capacity can be doubled to 16,000 when unicast Reverse Path Forwarding (uRPF) is disabled, allowing for more efficient routing and management of network traffic. Additionally, the module can handle an IPv4 Host Table of up to 8,000 entries, enabling it to manage a large number of host connections seamlessly. For applications that rely on IP Multicast, the N55-M160L3 supports up to 4,000 IP Multicast Routes, facilitating efficient distribution of data across multiple recipients.
  • L3 Interfaces: The module supports up to 1,000 Layer 3 interfaces, allowing for the interconnection of multiple networks within a diverse routing environment.
  • VRF (Virtual Routing and Forwarding): With support for up to 1,000 VRF instances, the N55-M160L3 enables the segmentation of network traffic for enhanced security and efficient traffic management.
  • Field-Replaceable Units (FRUs): The design includes FRUs, ensuring minimal downtime and easy maintenance by allowing defective parts to be replaced without taking the entire system offline.
The module is powered by a newer version of the Layer 3 ASIC, which is engineered to deliver high performance. This includes a throughput capacity of up to 160 Gbps or 240 million packets per second (mpps), providing the speed and efficiency needed for high-demand networks. The form factor of the N55-M160L3 is hot-swappable, meaning it can be replaced or upgraded without shutting down the system, further enhancing the operational continuity and flexibility of the network infrastructure. The N55-M160L3's hardware specifications make it an ideal choice for organizations looking to expand their network's Layer 3 capabilities. Whether it's for handling high volumes of traffic, supporting complex routing policies, or providing robust multicast services, this module offers the necessary features to meet and exceed the requirements of modern network environments. Its combination of capacity, performance, and maintenance features ensures that networks equipped with the Cisco N55-M160L3 can deliver high levels of reliability, security, and efficiency.
